FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with heart transplant is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about heart transplant, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to heart transplant, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on heart transplant. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to heart transplant, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on heart transplant. The Editors

CHAPTER 1. STUDIES ON HEART TRANSPLANT Overview In this chapter, we will show you how to locate peer-reviewed references and studies on heart transplant.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and heart transplant, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “heart transplant” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Dental Management of the Heart Transplant Patient Source: General Dentistry. 40(2): 126-131. March-April 1992. Summary: This article brings readers up to date on the dental management of heart transplant patients. Topics include the historical development of heart transplantation, including survival rates, postoperative care, and patient selection; complications following heart transplantation, including graft rejection, immunosuppression, accelerated atherosclerosis of the graft coronary arteries, side effects of agents used for immunosuppression, and excess bleeding as a result of anticoagulation medicine; dental management of these patients, including the pretreatment dental evaluation, retention of teeth, treatment of patients with valvular disease, and preventive techniques; and managing invasive dental treatment for posttransplant patients, including the need for antibiotic prophylaxis, handling excessive bleeding and reactions to stress, the use of

steroids, and myocardial infarction. The authors conclude that the two most important roles for dentistry in managing heart transplant patients are to be involved before the transplant, so areas of active infection can be identified and treated before the start of immunosuppressive therapy, and to initiate an aggressive preventive dentistry program for the patient. 7 tables. 22 references. •
Reversion of Gingival Hyperplasia in a Heart Transplant Patient Upon Interruption of Cyclosporine Therapy Source: SCD. Special Care in Dentistry. 16(1): 18-21. January-February 1996. Summary: This article presents a case of reversion of gingival hyperplasia in a heart transplant patient upon interruption of cyclosporine therapy. A heart transplant patient undergoing a combined cyclosporine and prednisone treatment was monitored during the 18 months following transplantation. Complete oral and dental examinations were performed on a set schedule; data collected included gingival hyperplasia secondary to cyclosporine use, and clinical and periodontal variables. Cyclosporine treatment was replaced by azathioprine treatment in month 10 because the patient was experiencing nephrotoxicity. Between months 9 and 18, gingival hyperplasia regressed by 26.5 percent due to reductions in the fibrous connective tissue mass, fibroblasts, and inflammatory infiltration. A control group included 13 heart transplant patients subject to equivalent conditions except for discontinuance of cyclosporine treatment. Seven of these patients had developed hyperplasia by month 9. Results provide further evidence for the causal relationship between cyclosporine therapy and gingival hyperplasia and suggest that this side-effect is reversible. 7 figures. 7 references. (AA-M).
Federally Funded Research on Heart Transplant The U.S. Government supports a variety of research studies relating to heart transplant. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to heart transplant. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore heart transplant. The following is typical of the type of information found when searching the CRISP database for heart transplant: •

Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: The broad long-term objectives of this proposal are to achieve targeted, efficient and durable gene transfer to the transplanted heart and, using biologically relevant genes for isoforms of nitric oxide synthase (NOS), to normalize coronary arterial vasoreactivity and reduce cardiac allograft vasculopathy (CAV) after allotransplantation in both a small and large animal model. The central hypotheses of this proposal are that, using the unique transplant setting, targeted, efficient and durable gene transduction of blood vessels of the heart or the myocardium can be achieved and that abnormalities in coronary vascular relaxation and the development of CAV after heart transplantation can be reduced by efficient cardiac transduction with endothelial or inducible NOS (eNOS or iNOS). CAV is the greatest obstacle to long-term patient survival after cardiac transplantation. Gene therapy may be particularly applicable in the setting of transplantation as the donor organ is uniquely available for genetic modification ex vivo prior to implantation into a recipient. Major challenges to successful clinical gene genetic modification ex vivo prior to implantation into a recipient. Major challenges to successful clinical gene therapy include the need for optimal vectors and delivery systems to transfer genetic material to tissues in vivo. Recently, for the first time, physical and chemical conditions of gene delivery to the heart have been shown to allow selective targeting of the vector to the media of the coronary arteries of the myocardium. Using a normothermic perfusion system, the usual period of storage of the donor heart before transplantation can be transformed into a period for optimal gene delivery without affecting the viability of the graft. The first aim of transformed into a period for optimal gene delivery without affecting the viability of the graft. The first aim of the current proposal is to identify the most suitable vector (adenovirus or lentivirus) and delivery system using chemical modification of a normothermic perfusion system for efficient, targeted and durable gene delivery in the heterotopic rat heart transplant model. The second aim is to study, using the most suitable vector and same delivery system from Specific Aim 1, the effects of eNOS or iNOS gene transfer to either the coronary vasculature or myocardium of the donor heart on coronary arterial vascular reactivity and on CAV after heterotopic pig heart allotransplantation. NOS will be studied as the gene of choice as reduced nitric oxide bioavailability is characteristic of vessels undergoing CAV. Abnormal endothelium dependent relaxation precedes CAV, so that successful NOS gene transfer might be expected to impact on the early stages of the disease. Before gene transfer technology to the transplanted heart can progress to the clinic, satisfactory experience in a large animal model will be necessary. The porcine model is particular suitable from a physiological and pathological viewpoint and is also the animal of choice for future clinical xenotransplantation. Success in achieving the specific aims of this proposal opens up the potential for clinical gene therapy to avoid CAV after heart transplantation. Implications also exist for the application of these techniques for the modification of non-allograft arteriosclerosis. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: AIF-1 EXPRESSION IN VSMC GROWTH AND ARTERIOPATHY Principal Investigator & Institution: Autieri, Michael V.; Assistant Professor; Physiology; Temple University 406 Usb, 083-45 Philadelphia, Pa 19122 Timing: Fiscal Year 2002; Project Start 20-MAR-2001; Project End 28-FEB-2005 Summary: (Applicant's abstract): Vascular restenosis induced by arterial trauma is one of the most critical factors which limits the success o solid organ transplantation and coronary interventional procedures. A popular hypothesis is that the cytokine-induced
6
Heart Transplant
activation and proliferation of VSMC in the media, culminating in intimal hyperplasia, is the most critical cellular event in formation of both cardiac allograft vasculopathy (CAV) and balloon angioplastyinduced restenosis. Identification and functional characterization gene products involved in VSMC activation is a promising approach for the identification of targets to combat proliferative arteriopathy observed in vascular proliferative disorders. Our hypothesis is that allograft inflammatory factor-I (AIF-1) promotes development of vascular proliferative disease based on its ability to respond to inflammatory cytokines and participate in the growth stimulatory pathways leading to proliferation of VSMC. We have recently shown that modulation of AIF- 1 levels in human VSMC impacts the growth of these cells. The first aim of this project will determine the mechanism of AIF-l growth promoting effects in human VSMC through a combination of flow cytometric analysis and investigation of expression and turnover of cell cycle-associated proteins. We will also identify regions that mediate these effects by site-specific modification of the AIF- 1 protein. We have determined that AIF- 1 partners with several cytoplasmic proteins, including a newly described growth factor-activated lipid kinase termed LCBK5. The second aim of this proposal will determine the functional significance of the AIF- 1-LCBK5 interaction and characterize the other AIF-1interacting peptides we have identified. Expression of AIF- 1 transcript is induced in mitogen-stimulated peripheral blood lymphocytes (PBL), and its expression in endomyocardial biopsies from transplanted hearts correlates with ISHLT rejection scores. A final aim of this proposal will correlate AIF-1 transcript levels in endomyocardial biopsies and PBL from heart transplant recipients with development of arteriopathy as determined by several clinical and imaging indices. It is anticipated that completion of these studies will implicate expression of this novel protein as a target of anti-restenotic therapy and a surrogate marker of transplant restenosis.

FAS/FASL-MEDIATED
Principal Investigator & Institution: Shirwan, Haval; Associate Professor; Microbiology and Immunology; University of Louisville University of Louisville Louisville, Ky 40292 Timing: Fiscal Year 2002; Project Start 15-DEC-2001; Project End 30-NOV-2005 Summary: Transplantation of vascularized allografts is an effective therapeutic alternative for patients with end-stage organ failure. Transplantation of organs between genetically different individuals, however, is limited by our ability to control the immunological rejection of the graft by the recipient. Immunosuppressive drugs may reduce the severity of rejection, but fail to create a state of permanent specific tolerance to the graft. We herein propose an immunomodulatory approach using a modified form of FasL with potent apoptotic activity to eliminate alloreactive T cells for the prevention of cardiac allograft rejection and induction of tolerance. FasL-induced apoptosis is the main mechanism of activation-induced cell death that is responsible for immune homeostasis and self-tolerance. The use of wild type (wt)FasL to prevent allograft rejection has been controversial. FasL is initially synthesized as a membranous molecule that induces apoptosis when prevention the cell surface. wtFasL is also shed from the cell surface by metalloproteinases within minutes of expression and the soluble form is antiapoptotic and chemotactic for neutrophils. We hypothesize that FasL can be used as an immunomodulatory molecule if its apoptotic activity is separated from anti-apoptotic and chemotactic functions. We generated modified forms of FasL with potent apoptotic activity and developed a novel approach to express FasL at the protein level on the surface of antigen- presenting cells (APCs) and vascular endothelium within 1 hour. In
Studies
7
preliminary experiments, we demonstrated that delivery of FasL on donor APCs blocked alloreactive responses in naive and presensitized animals and prevented islet allograft rejection. Expression of FasL protein on vascular endothelium under conditions adapted from clinical settings prolonged survival of cardiac allografts. In this proposal, rats and mice will be immunized with allogeneic APCs expressing FasL at various times pre-and post- transplantation. FasL will also be expressed on the surface of heart endothelium for immune evasion and prevention of rejection. Several mutant and transgenic animals will be used to test whether apoptosis induced by FasL is the main mechanism of the observed immune nonresponsiveness. This protein-based approach may be readily applied to the clinic and may provide a significant advantage because of its safety and simplicity as compared with immunomodulatory approaches using DNAbased expression.

Project Title: AN ETHICAL ANALYSIS OF ORGAN ALLOCATION POLICIES Principal Investigator & Institution: Fox, Mark D.; Pediatrics; University of Oklahoma Hlth Sciences Ctr Health Sciences Center Oklahoma City, Ok 73126 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2008 Summary: (provided by applicant): The purpose of this career development award is to enable Dr. Fox to develop the requisite skills to become an independent investigator, scholar, and resource in transplant ethics and policy. Through a structured program of didactic training and mentored research, the applicant proposes to develop an "evidence-based" ethical analysis of organ allocation policy, with specific reference to heart transplantation. This ethical analysis will be predicated on the development of skills in health services/outcomes research relevant to transplantation. The overall goal of this project is to provide an evidence-based ethical analysis of allocation policy informed by data regarding cardiac transplantation outcomes, and to determine if the impact of the policy changes enacted matches the stated goals of allocation policy. The fundamental hypothesis to be tested is that the changes in the allocation policy for heart transplantation have not produced outcomes consistent with the stated goals for transplantation. This hypothesis will be systematically pursued through the following five specific aims: 1) to develop methods for analyzing clinical outcomes for patients listed for cardiac transplantation in the United States, using the Scientific Registry of Transplant Recipients database; 2) to examine changes over time in the allocation policy regarding heart transplantation, with particular attention to how criteria defining medical urgency impact allocation decisions; 3) to evaluate the impact of changes in heart allocation policies with respect to various outcomes (pretransplant mortality, posttransplant survival, and the need for re-transplantation); 4) to examine differences in value assigned to possible outcomes, as reflected in preferences for allocation strategies, among patients and non patients, transplant professionals and other health care providers; and 5) to develop a policy analysis of other potential models for heart allocation to determine their clinical, political, and moral viability. Upon completion of the career development award, Dr. Fox will be able to function as an independent investigator in the interface between ethics and health services research.

Project Title: ANTIMHC ANTIBODY EFFECTS ON ENDOTHELIUM AND MUSCLE Principal Investigator & Institution: Reed, Elaine F.; Professor; Pathology and Laboratory Medicine; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2003; Project Start 01-JAN-1999; Project End 31-DEC-2007 Summary: (provided by applicant): Accelerated transplant arteriosclerosis (TA), a manifestation of chronic rejection, is the leading cause of graft failure. The development of anti-HLA antibodies to donor HLA antigens is a major risk factor associated with TA. The overall goal of this proposal is to elucidate the signal transduction pathways that mediate HLA class I induced cell proliferation and the development of TA. Under specific aim #1, we will establish whether anti-HLA antibodies induce tyrosine phoshphorylation of focal adhesion proteins and assembly of signaling complexes via an actin cytoskeleton dependent pathway in endothelium and smooth muscle. For this, we will establish whether exposure of cultured endothelial cells (EC) and smooth muscle cells (SMC) to monoclonal anti-HLA antibodies and anti-HLA antibodies from transplant patients with chronic rejection is accompanied by FAK phosphorylation and the generation of FAK/Src/Paxillin signaling complexes. We will determine if the phosphorylation of focal adhesion proteins is accompanied by alterations in the organization of the actin cytoskeleton and in the assembly of focal adhesions. We will explore the role of ROK, MLC phosphatase and ERK as upstream components of the class I signaling pathway. We will also determine if class I signaling stimulates antiapoptotic signals by inducing tyrosine phosphorylation of PI3-kinase, Akt and Bad. Under specific aim #2, we will identify the signaling pathways leading to MHC class I induced FGF receptor translocation in EC and SMC. For this, we will determine the role of the actin cytoskeleton, phosphorylation of FAK, Src, paxillin and assembly of focal adhesions in class I mediated FGFR translocation to distinct subcellular locations using flow cytometry and confocal microscopy. We will also assess the importance of ROK, ERK, MLC phosphatase in class I mediated FGF receptor translocation. The contribution of the FGF receptor tyrosine kinase activity and ERK phosphorylation to class I induced cell proliferation will be established. Under aim #3, we will assess the expression of class I induced tyrosine phosphorylation, FGF receptors and anti-apoptotic proteins in clinical biopsy specimens from cardiac allografts with and without evidence of transplant arteriosclerosis. We will determine the correlation between protein phosphorylation events and protein expression with the incidence and time of onset of transplant arteriosclerosis and development of anti-HLA antibodies.

Project Title: APCS IN CHRONIC HEART REJECTION Principal Investigator & Institution: Rosengard, Bruce R.; Assistant Professor; Surgery; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-MAY-2001; Project End 30-APR-2004 Summary: (Verbatim from the Applicant's Abstract): Cardiac transplantation is established therapy for the treatment of end-stage heart failure. However, chronic rejection in the form of accelerated arteriosclerosis remains the primary cause of late

death after heart transplantation. Despite the development of several new drugs to combat rejection, the incidence of this form of chronic rejection has not changed. We have hypothesized that endothelial cells, which line coronary arteries, are capable of directly activating CD8+ T cells, which may play an important role in the development of graft vascular disease. We have established both in vitro and in vivo mouse models to study this process. The broad objective of this grant proposal is to define the differences in the ability of murine endothelium to activate CD4+ and CD8+ T cells in vitro and then to use analogous in vivo models to define the allorecognition pathways and effector mechanisms responsible for graft vascular disease. To achieve this goal, we will: 1. Test the hypothesis that endothelium activates both unprimed and primed CD8t T cells preferentially due to a less stringent requirement for costimulation. 2. Test the hypothesis that endothelium is a suitable target for CD8+ T cell cytotoxicity predominantly via the Fas/FasL pathway. 3. Test the hypothesis that graft vascular disease is a CDK about-dependent process. In summary, this proposal will determine whether endothelium has the capacity to stimulate CD8F T cells and the ability to act as targets for CD8+ cytotoxic T cells, which is sufficient to induce graft vasculopathy in a mouse model. Insights from this study will undoubtedly provide information that will lead to rational strategies to help prevent this lethal complication of human heart transplantation.

Project Title: APPLIED GENOMICS IN CARDIOPULMONARY DISEASE Principal Investigator & Institution: Haponik, Edward F.; Professor of Internal Medicine; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-JUL-2004 Summary: The Clinical Core will serve as the coordinating center for patient recruitment, specimen procurement and data base management. It is the mission of this Core to identify and provide disease-specific candidate genes from patients with such clinical disorders as acute lung injury, COPD, cystic fibrosis, asthma, pulmonary hypertension, pulmonary fibrosis, ischemic heart failure and both lung and cardiac transplant rejection. This core will also be responsible for the establishment of a Cardiopulmonary Tissue Repository that will maintain an archive of cryopreserved tissues and maintain an accurate data base of patient demographic and clinical data for correlation with biological end points produced by cDNA microarray. Following patient consent and registration, tissue samples and peripheral blood are delivered to the Core laboratory. The freezing facility will also serve as a repository for cyropreserved human lung and cardiac specimens. The Core Investigators will meet regularly to review all diagnostic materials on each specimen procured including histochemical stains and biopsies in order to determine a precise diagnosis and relevant demographic and clinical data for entry into the Project's data base which will include critical variables for the analysis of the biological data obtained.

Summary: (provided by applicant): The Bio-Rad galactomannan enzyme immunoassay (GM EIA) will soon be submitted to the FDA for approval as an aid to diagnose aspergillosis, a frequent cause of infectious death in immunosuppressed patients. Our preliminary studies suggest that the assay may also be used as a screening test to enable early diagnoses; however, the optimal cut-offs for positivity have not been determined. Defining cut-offs to optimize performance is critical for patients who have different manifestations of infection (endobronchial vs. invasive), such as in solid organ transplant recipients, and in children, who appear to have frequent false-positive results. The studies proposed in this project will define parameters to use the GM EIA in multiple different patient populations, using clinical samples obtained from a large ongoing FHCRC longitudinal protocol in adult allogeneic hematopoietic stem cell transplant (HSCT) recipients, and samples obtained from multicenter trials sponsored by the NIH. Aim 1 will define parameters for use of the GM EIA as an early diagnostic test for aspergillosis in adult allogeneic HSCT patients. Studies will be performed to determine the lower limit of GM detection, identify clinical factors that impact levels of circulating GM, and to determine the role of GM EIA applied to non-blood fluids (bronchoalveolar lavage fluid and urine). Aim 2 will define appropriate cut-offs for positivity and characterize performance of the GM EIA as a diagnostic assay for aspergillosis in high-risk solid organ transplant recipients. To do this, longitudinal sample collection will be performed in a protocol conducted as a companion to an ongoing CDC-sponsored multicenter surveillance study. Aim 3 will define parameters for use of the GM EIA as an early diagnostic test for aspergillosis in neutropenic children. To determine the appropriate cut-offs for positivity in children, GM EIAs will be performed on serial sera obtained from children at high risk for aspergillosis after treatment with induction chemotherapy for AML, and after cord blood transplant. Companion protocols will be performed to collect sera as part of ongoing multicenter studies performed by the Children' s Oncology Group and the NHLBI Cord Blood Transplantation Study. Studies will be performed to determine if false-positivity of the GM EIA in children corresponds with gut translocation of GM during periods of mucositis, by measuring surrogate markers for GI integrity in a case-control study. This project is enabled by the cooperative activities of FHCRC investigators, Bio-Rad Laboratories, and several multicenter networks supported by the CDC, NIAID, and NHLBI.

Project Title: CASPASE INHIBITION OF APOPTOSIS, INFANT CARDIAC SURGERY Principal Investigator & Institution: Mcgowan, Francis X.; Associate Professor; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2002; Project Start 01-JAN-2001; Project End 31-DEC-2005 Summary: (Verbatim from Applicant's Abstract): A major limitation to successful outcome of the repair of congenital heart lesions is the development of ventricular dysfunction. While the etiology is undoubtedly multifactorial, evidence suggests that it in large part may be due to myocyte loss resulting from chronic cyanosis, prolonged exposure to abnormal hemodynamic loads, and one or more episodes of ischemiareperfusion required for cardiac surgery. Death of myocytes can occur by either necrosis or apoptosis. In contrast to necrosis, apoptosis is the orderlv disassemblv of the cell by specific enzymatic pathways that are triggered by a wide variety of genetic, environmental and toxic stimuli. Recently, human and animal studies have shown that hypoxia, ischemia-reperfusion, abnormal mechanical loading, and inflammation can

cause significant cardiomyocyte apoptosis. This occurs during myocardial ischemia, infarction, hypertrophy, and heart failure. The role of apoptosis in infants undergoing cardiac surgery is not known. Based upon this information and preliminary data from our laboratory, we believe that myocyte apoptosis is a significant problem in infants with normal and hypertrophied myocardium subjected to surgical ischemiareperfusion. This loss of myocytes will be particularly injurious to the infant myocardium because of the loads imposed by future growth and residual hemodynamic abnormalities. Because the pathways triggering apoptosis in this setting are multiple, we have chosen to focus on the role of the caspase enzymes. Caspases are the focal point of propagation and execution of apoptosis, and are directly responsible for the proteolytic cleavage of specific proteins required for the process to occur. Experiments in Aim I will be the first to l)define which caspases are expressed, activated, and what key intracellular proteins are thereby cleaved in normal and hypertrophied myocardium exposed to surgical ischemia-repercusion, 2)quantify the amount of apoptosis that occurs in this setting, and 3)determine the effects of specific caspase inhibition on these events. Using a novel working heart transplant model with normal and hypertrophied infant hearts, Aim II will answer a question of critical importance, namely what is the effect of inhibition of caspases and apoptosis on long-term myocardial inflammation, fibrosis, and recovery of function? These experiments will be the first to study the beneficial versus harmful roles of apoptosis in myocardial ischemia-reperfusion injury. Overall, these studies will provide valuable new insights into therapeutic targets and strategies to preserve myocardial function in these patients. The results are also likely to be applicable to patients with ischemia, myocardial infarction, and heart failure. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CCR2 AND CCR5--ATHEROSCLEROSIS AND CONTROL OF EXPRESSION Principal Investigator & Institution: Charo, Israel F.; Professor of Medicine; J. David Gladstone Institutes 365 Vermont St San Francisco, Ca 94103 Timing: Fiscal Year 2002; Project Start 15-JUL-1994; Project End 30-JUN-2003 Summary: (Adapted from the application) The overall goal of this proposal is to determine the role of chemokine receptors in vascular disease. Chemokines (chemotatic cytokines) specifically attract leukocytes by activating G-protein-coupled receptors. The investigators have focused their efforts on two of these receptors, CCR2 and CCR5, which were cloned in this laboratory and which are the major chemokine receptors on monocytes. During the first funding period, the investigators examined the structure/activity relationships of these two receptors with regard to ligand binding and signaling. The work proposed in the current application will extend these in vitro studies to in vivo models, taking advantage of our recent creation of a CCR2 knockout mouse. The first goal of the proposal is to determine the role of CCR2 in two forms of vascular disease: atherosclerosis and the accelerated arteriosclerosis of allogeneic cardiac transplants. The investigators will cross the CCR2-/- mice with apoE-/- mice and perform detailed atherosclerosis studies. The investigators will also perform heterotopic transplants of allogeneic hearts into the CCR2-/- mice and determine whether CCR2 plays a role in chronic myocardial rejection and transplant arteriosclerosis. The second goal is creating CCR2/CCR5 double-knockout mice. The investigators will selectively delete these receptors and simultaneously "knock in" lacZ under the control of the CCR2 promoter and green fluorescent protein (GFP) under the control of the CCR5 promoter. This approach will generate chemokine receptor knockout animals, as well as provide a sensitive means for detecting the endogenous in

vivo expression of CCR2 and CCR5. Differential regulation of chemokine receptors clustered on chromosome 3 (3p21.3-24) may provide specificity in inflammation and immunity. The third goal is to determine the tissue-specific expression and transcriptional regulation if selected CC receptors. The investigators will use the hemizygous CCR2/CCR5 double-knockout mice (CCR2+/LacZ, CCR5=/GfP), as well as transgenic mice created with large fragments of human genomic DNA, to follow the expression of these two receptors in models of human disease. the experiments proposed in this grant will utilize novel and complementary approaches to provide the first detailed information on the role of chemokines and chemokine receptors in vascular disease.

Project Title: CD28/B7 COSTIMULATION BLOCKADE-RESISTANT GRAFT REJECTION Principal Investigator & Institution: Hancock, Wayne W.; Professor; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 15-FEB-2003; Project End 31-JAN-2008 Summary: (provided by applicant): Failure to stem the incidence of chronic rejection continues to diminish the long-term benefits of transplantation. Experimental data suggest the importance of tolerance induction as a means to prevent chronic rejection and minimize drug toxicity, and blockade of CD28/B7 and/or CD154/CD40 can markedly prolong allograft survival, in some cases leading to permanent engraftment. However, costimulation blockade-resistant allograft rejection can still occur. This application is based around recently recognized CD28 and B7 homologs whose ligands are broadly expressed in peripheral tissues, and which likely regulate effector T and B cell responses. We will study the roles of ICOS/B7RP-1 and PD-1/PD-L1/PD-L2 in host alloresponses using murine models of cardiac and islet allograft rejection, thereby allowing consideration of rejection in primarily revascularized vs. non-revascularized grafts, as well as validation of heterotopic cardiac graft data in the more stringent, lifesupporting islet allograft system. Aim 1 will determine the mechanisms by which the ICOS/B7RP-1 costimulatory pathway can regulate T and B cells responses in allograft recipients in vivo, such that targeting of this interaction can diminish chronic rejection and promote tolerance induction. We will dissect the contributions of ICOS and B7RP-1 to T and B cell responses in wild-type as well as CD28- and CD154-independent responses. We anticipate these studies will provide key mechanistic insights into the importance of ICOS/B7RP-1 in ongoing host alloresponses, and how targeting of this pathway can best promote allograft tolerance. Aim 2 hypothesizes that tissue-specific immune responses are regulated by the PD-1/PD-L1/PD-L2 pathway, and we propose to analyze the extent to which manipulation of this pathway can facilitate long-term allograft survival. Our preliminary data show that stimulation of a negative signal through ligation of PD-1 can dampen host alloresponses, including those underlying costimulation blockade-resistant allograft rejection. We will expand these studies to dissect how interactions of PD-1 with its ligands can be promoted to achieve therapeutic effects in allograft recipients. Success in this work would provide a rationale for testing in non-human primates, and may ultimately improve the management and long-term results seen in patients undergoing organ transplantation or receiving islet allografts by promoting graft tolerance and decreasing the incidence of chronic rejection.

Project Title: CD4 T CELL DEPENDENT ACUTE CARDIAC ALLOGRAFT REJECTION Principal Investigator & Institution: Pietra, Biagio A.; Pediatrics; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 31-AUG-2005 Summary: Numerous studies indicate that CD4 T cells are required for acute cardiac allograft rejection. However, the precise role for CD4 T cells in this response has remained ambiguous due to the multi-potential properties of this T cell subpopulation. We have recently demonstrated the capacity of CD4 T cells to serve as direct effector cells of cardiac allograft rejection. CD4 T cells are both necessary and sufficient for acute graft rejection as indicated by adoptive transfer experiments in immune-deficient SCID and rag-/- recipients. Acute CD4 T cell-mediated rejection requires MHC class II expression by the allograft, implicating the importance of direct graft recognition in this response. While CD4 T cells can serve as effector cells for primary acute cardiac allograft rejection via direct donor recognition, they can also serve as helper cells via the indirect response leading to the function of other graft-reactive lymphoid populations. The difficulty in examining the relative contribution of these CD4-dependent pathways to acute allograft rejection is that these responses normally occur simultaneously. In the adoptive transfer model systems proposed, the consequence of direct (donor MHCrestricted) and indirect (host MHC-restricted) CD4 reactivity can be studied independently. Thus, the overall goals of this proposal are to: (1) Clarify the nature of acute CD4-mediated cardiac allograft rejection via direct donor recognition, and (2) Clarify the pathway of 'indirect' CD4 reactivity that results in help for other graftreactive CD8 T cells and/or B cells. These general goals will be examined through the following specific aims: I) Define the recognition and costimulatory requirement(s) of direct CD4-dependent cardiac allograft rejection. This aim will test the novel hypothesis that antigen recognition and costimulation can be delivered by different APCs in vivo. II) Determine the effector mechanism(s) of CD4-dependent direct cardiac allograft rejection. This aim will test the hypothesis that direct, CD4-mediated rejection is cytokine-dependent in vivo. III) Determine the nature of indirect CD4 T cell 'help' for cardiac allograft rejection. This aim will test the hypothesis that indirect CD4 T cells can provide 'unlinked' T cell help for graft reactive CD8 T cells. The information obtained will be useful in understanding the basic immune mechanisms of human cardiac transplantation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: CD40 COSTIMULATION AND TRANSPLANTATION Principal Investigator & Institution: Perkins, David; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-JAN-1999; Project End 31-DEC-2003 Summary: (adapted from applicant's abstract) Following transplantation, acute rejection is recognized as the most frequent serious complication and the best predictor of chronic rejection, a major cause of long term graft loss. T cells are essential for initiating and maintaining acute rejection. Early intervention in transplant rejection necessitates understanding the mechanisms of T cell activation, as related to allograft survival. The principal investigator and others have found that blockade of CD40 signals prolongs graft survival. The goal of this proposal is to determine which CD40 regulated functions mediate graft rejection. CD40 signals are transduced by both NF-kB-dependent and independent mechanisms. The PI has found that in vivo inhibition of NF-kB activation

Heart Transplant
with a dominant negative transgene or by deletion of c-Rel prolongs allograft survival. Thus, one focus will be on the role of CD40-regulated actions that are NF-kB-dependent. The investigators propose the hypothesis that blockade of the CD40/CD40L costimulatory pathway prolongs allograft survival by NF-kB-dependent mechanisms. To test this hypothesis, they will employ an adoptive transfer model of cardiac transplantation using double transgenic lines that express the DO11 TCR transgene, which is cross-reactive with I-Ab, plus null alleles of either CD40, CD40L, c-Rel, or IkBa (DN), a dominant negative inhibitor of NF-kB. Transfer of cells from these animals into Balb/c recipients of C57Bl6 cardiac grafts will provide a means to examine in vivo and in vitro the molecular mechanisms governing CD40/CD40L costimulatory effects. Aim 1 will determine the role of CD40 ligand signals on T cell activation, proliferation, unresponsiveness, and cytokine secretion. Aim 2 will determine the cellular mechanisms by which CD40 expressed on T cells regulates allograft rejection by mechanisms of activation and apoptosis involving FasL and TNF-a signals. Aim 3 will investigate the molecular mechanisms by which activation of NFkB controls allograft survival. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CELLULAR BASIS OF CMV ACCELERATED VASCULOPATHY Principal Investigator & Institution: Nelson, Jay A.; Director & Professor; Molecular Microbiology and Immunology; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): The long-term goal of this project is to determine the role of viral pathogens in the development of vascular diseases such as atherosclerosis, restenosis, and transplant vascular sclerosis (TVS). All of these diseases are the result of either mechanical or immune related injury followed by inflammation and subsequent smooth muscle cell (SMC) proliferation and/or migration from the vessel media to the intima, which culminates in vessel narrowing. Clinical studies have directly associated human cytomegalovirus (HCMV) with the acceleration of TVS and restenosis as well as atherosclerosis. However, the mechanism(s) involved in the acceleration of vascular disease by HCMV is unknown. Studies by our group and others have implicated endothelial cells (EC), macrophages (MDM) and SMC as potential reservoirs of the virus in the host. Unfortunately, an animal model for HCMV is unavailable. However, mouse cytomegalovirus (MCMV) provides an ideal system to study mechanisms of pathogenesis and cellular tropism in the mouse model. Recently, we have developed a mouse heart transplantation model of TVS, which exhibits all of the hallmarks of human disease. We have also shown that CMV accelerates the progression and severity of TVS. Therefore, in this project we will utilize the mouse TVS model in combination with MCMV to assess the role of viral infection of MDM and EC on the acceleration of disease. In the first specific aim, we will utilize MCMV EC and MDM tropic mutants, which inhibit growth of virus in these cell types to assess the contribution of viral infection of these cells in the acceleration of TVS. In the second specific aim, we will utilize mice which specifically express Cre recombinase in EC and MDM in combination with recombinant MCMV that contain Lox sites which inactivate the virus in the presence of Cre enzyme to assess the role of MCMV replication in MDM and EC in the acceleration of TVS. In the last specific aim, we will examine viral mechanisms which accelerate TVS through ablation of MCMV genes which mediate inflammatory events.

Project Title: CELLULAR MECHANISMS OF PTLD IN TRANSPLANT RECIPIENTS Principal Investigator & Institution: Martinez, Olivia M.; Associate Professor; Surgery; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 01-MAY-1997; Project End 19-SEP-2003 Description (provided by applicant): Post-transplant lymphoproliferative disease (PTLD) is a morphologically complex disorder that ranges from benign B cell hyperplasia to malignant lymphoma. Epstein-Barr virus (EBV) B cell lymphomas are the hallmark of PTLD and are associated with significant morbidity and mortality. During the previous funding period we identified specific signaling pathways that confer a survival advantage to EBV-infected B cells despite significant frequencies of EBVspecific CD8+ T cells in the circulation of transplant recipients. We also established that the immunosuppressive sirolimus (RAPA) can directly inhibit the growth of EBVinfected B cells. The objective of this research is to defme the immune alterations that contribute to the autonomous growth of EBV-associated B cell lymphomas. To accomplish this objective we propose four Specific Aims. In Specific Aim 1 we will determine the requirement for IL- 10 and its associated Jak/STAT signal transduction pathway in sustaining the growth of EBV-infected B cells. Dominant negative (DN) forms of the 1L-lO receptor (IL-1OR), STAT1 and STAT3 will be transduced into EBVinfected B cells using a lentivirus-based retroviral transduction system to evaluate the effect on cell growth. A SCID mouse model of EBV+ B cell lymphoma will be used to test the effect of blockade of IL-lO on tumor growth. Specific Aim 2 will examine the mechanism by which EBV-infected B cells are resistant to death receptor-induced apoptosis. The proximal events in the Fas and TRAIL-DR4/DR5 cell death pathways will be characterized by two-dimensional gel electrophoresis and DNA microarray. The role of the decoy receptors DcR1 and DcR2 in resistance to TRAIL cytotoxicity will be examined. The contribution of the EBV latent genes LMP1 and EBNA2 to resistance to apoptosis will also be determined. In Specific Aim 3 MHC/peptide tetramers containing immunodominant epitopes of EBV antigens will be used to identify EBV-specific CD8+ T cells in transplant recipients and the functional properties of these T cells will then be assessed. The effects of immunosuppression on the generation of functional EBVspecific CD8+ T cells will be determined in the SCID/EBV B cell lymphoma model. Aim 4 will determine the mechanism by which RAPA inhibits growth of EBV-infected B cells with specific focus on apoptosis, cell cycle proteins and the JakISTAT pathway. Elucidation of the immune mechanisms involved in PTLD will provide novel opportunities for treatment of this serious disease. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: COMPARATIVE APPROACH TO GENOMICS OF COMPLEX TRAITS Principal Investigator & Institution: Goldschmidt-Clermont, Pascal J.; Professor and Chair; Medicine; Duke University Durham, Nc 27706 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant) The determinants of genetic susceptibility for most common traits are complex, likely to involve contributions from multiple gene variants. These variations in gene function that affect critical phenotypes can represent amino acid replacements as well as extragenic differences that might affect expression levels; in most instances, these are single nucleotide polymorphisms (SNPs). Although one would like to assay for these gene variants in a completely unbiased fashion, ultimately measuring the contribution of every variant of every gene, this is obviously impractical at this point in time. An alternative strategy is to identify those genes most likely to
16
Heart Transplant
make contributions to disease variation, identify the variations within this group of genes, and then conduct association studies to link gene variants with disease phenotype. Using cardiovascular disease as a model system, this proposal describes a multi-dimensional approach to this overall problem. In particular, we will use multiple methods for the identification of candidate genes most likely to make contributions to disease variation within populations of patients. This work will take advantage of three unique clinical resources here at Duke. First, we have begun the collection of a large series of aorta samples from heart transplant donors as a source of vascular tissue for gene expression analysis. These samples are unique in the volume of the samples (hundreds) as well as the range of phenotype: early stages of atherosclerosis to advanced forms of the disease. As such, it provides an opportunity to match gene expression profiles with the development of disease in a very unique way. This will be the focus of work in Component 1 as well as statistical efforts in Component 5. Second, a large study of the genetics of early onset cardiovascular disease, representing a collaboration between Duke investigators and GlaxoSmith-Kline, offers the opportunity to identify loci that are linked with the development of disease. This provides a mechanism for the identification of additional candidate genes without any bias whatsoever, including whether the gene actually functions within cardiovascular tissue or not. This represents the focus of Component 2, and bioinformatic efforts in Component 6. The combined efforts of Component I and 2, taking different approaches to the identification of candidate genes, will then be the source of substrate to discover SNPs within this group of genes (Component 3). Much of this work will take advantage of existing information regarding SNPs as well as other major studies directed at cardiovascular disease. But, it will also necessitate efforts within this component to identify as exhaustively as possible those sequence variants that can then be the subject for assays in clinical populations. Third, and possibly the most important asset of this program, is the Duke Cardiovascular Database, an effort initiated some thirty years ago at Duke to follow the clinical course of every cardiovascular disease patient. As such, we now have access to over 40,000 patients who are being followed on a regular basis, creating a clinical dataset that is unmatched. This clinical dataset provides a completely unique resource for this study, both from the quantity as well as the quality of patient clinical data to allow the validation of candidate gene variants with disease variation. Thus, the SNPs identified in Component 3 will go into an expansive genotyping program (Component 4), to bring these candidate genes to a point of validation. A major challenge in an undertaking of such magnitude will be the statistical power to find associations in complex situations. Component 5, will develop the methodologies for understanding the complex gene expression datasets, will also develop the statistical approaches to the analysis of the complex genotyping studies. The program will also enhance and integrate with existing and developing educational programs in bioinformatics and genome technology at Duke (Component 6). This synergy will be of clear benefit to the program, bringing in talented investigators from multiple disciplines in each area critical for the program. Hence, our project will advance the frontiers of genome sciences and technology in the field of common traits. The culmination of our program will provide essential tools to clinicians to improve risk stratification of patients and to design novel preventive and therapeutic strategies.

Summary: (provided by applicant) The Clinical/Pathology Core will continue to coordinate the collection of tissue and blood samples at the time of transplantation and at the time the allograft is biopsied. Tissues from the explanted hearts and from selected endomyocardial biopsies will be collected. Blood/plasma samples will be collected from donor, recipient, blood bank, and from the spouse of the recipient at the time of transplantation. In addition, this core will act as the repository for all the relevant clinical data in support of these tissue samples. This core will examine the collected tissue and blood samples using general histology, routine immunohistochemistry and specialized coagulation assays in support of individual projects. Finally, this core will provide non-routine noninvasive analyses. Cardiac surgeons at Johns Hopkins have transplanted 337 hearts into human recipients during the last 18 years (to 8/31/01) and the demographics of these recipients are: by gender-93 female, and 244 male; by race- 39 African American, 291 Caucasian, and 7 other; and by age-29 children and 308 adults. During the current period of this program project 86 hearts were successfully transplanted (by gender-29 female, and 57 male; by race-23 African American, 57 Caucasian, and 6 other; and by age-4 children and 82 adults). After transplant, surveillance endomyocardial biopsies are performed every 10 days for the first month, every 14 days for second month, every month for months 3 to 6, and every 4 to 6 months, thereafter. Additional endomyocardial biopsies are performed when the symptoms dictate. 180 heart transplant patients were followed during the most recent year (9/1/00-8/31-01) and 600 endomyocardial biopsies were performed.

Project Title: CORE--HISTOPATHOLOGY Principal Investigator & Institution: Sedmak, Daniel D.; Professor and Chair; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: Chronic allograft rejection is the leading cause of renal and cardiac allograft failure. The Long term goal of this core is to assist investigators in acquiring the experimental data necessary for the successful investigation of this disease process. In this program project human cardiac biopsies will be extensively utilized, as well as murine cardiac grafts, for the investigation of chronic rejection; however, meaningful studies with model will require the use of standardized tissue sections, special stains, and quantitative morphometric measurements. Therefore, the short term goals of the Histopathology core are to provide a centralized and standardized histology, immunohistochemistry, and automated morphometric analysis service for all projects. As a central core service it will guarantee a high level of uniformity, consistency and quality that will facilitate comparison of experimental results between the three program projects. The Specific Aims are to (1) provide a central histopathology laboratory for all projects, (ii) provide a central immunohistochemistry laboratory for the detection of disease-related antigens in frozen or formalin-fixed tissues, (iii) provide an automated image analysis and morphometrics service that will provide consistent and uniform measurements of transplant vascular sclerosis and myocardial fibrosis in murine heterotopic heart transplants and human explanted heart autopsy specimens, and (IV) provide a laser capture microdissection (LCM) service that will provide morphometric-like cell populations from thin sections of formalin fixed paraffinembedded or frozen tissues of both animal and human tissues for molecular analysis. The core will be located in The Ohio State University Medical Center and utilize the preexisting Department of Pathology laboratories.

Project Title: CORE--HUMAN CARDIAC TISSUE REPOSITORY Principal Investigator & Institution: Rodriguez, E Rene.; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: Human Cardiac Tissue Repository Core. To study the immunopathogenesis of human cardiac allograft arteriosclerosis (GA), the Human Cardiovascular Tissue Repository will continue to build on the highly successful existing tissue bank established at Hopkins. The functions of the core will be: 1. To banked fresh-frozen tissues include sections of myocardium and coronary arteries. The number of hears from patients undergoing a re-transplantation have steadily been in the range of 5-15% of all hearts transplanted (average 30 hearts per year) at Hopkins during the last 10 years. The infrastructure in place for this core allows for procurement of human hearts at the time of surgery. Cardiac tissues are triaged and processed immediately as needed by the different projects in this proposal (e.e. freezing, cell culture, organ culture) by a cardiac pathologist as part of the evaluation of the specimen. In addition to the fresh and frozen tissue repository, there is formalin-fixed paraffin- embedded tissue from human heart transplant recipients, which currently includes over 6,000 heart biopsies, 54 autopsies and 223 explanted hearts, including 24 explanted from heart transplant recipients who were re- transplanted because of allograft vasculopathy in their first grafts. 2. Another function of this core be to provide clinical data striped from any identifies to individual investigators. These database is supported by departmental funds and are provided free to the Core. 3. Comprehensive pathologic examination of the tissues will be performed with advanced pathologic techniques in our facilities at Hopkins Molecular Pathology, tissues will be performed with advanced pathologic techniques in our facilities at Hopkins Molecular Pathology, Research Immunohistochemistry, and Research Histology laboratories. 4. Cardiac allograft arteriosclerosis lesions will be microdissected and analyzed with an array of ProteinChips/TM to identify protein expression alterations in the allograft important mechanism in the pathogenesis of cardiac allograft arteriosclerosis. Accordingly, the proteomics core will focus on the role of IFN-gamma and the molecules that both, regulate IFN-gamma and are regulated by IFN-gamma, leading to proliferation of TH1 cells. The proteomics core will correlate expression of molecules identified in projects 1, 2 and 3 taking advantage of phage-peptide-display libraries and candidate gene sequences identified in core E (RNA microarrays). Core D will microdissect cells from human coronary arteries. Microdissection will allow the comparison of the proliferative cell component present in the intima of GA vessels with musculopathy and smooth muscle cells from the media of transplant arteries and controls. The power of the proteomics analysis with the ProteinChipTM technology is that femtomolar amounts of proteins can be identified, thus requiring only a few hundred to a few thousand cells from human arteries to obtain protein expression information. The integration of this core with the projects in this proposal will provide scientific basis to develop effective approaches to early diagnosis of GA and provide information of possible targets for early therapeutic intervention, which is crucial to lengthen the longevity of the allograft.

Timing: Fiscal Year 2002; Project Start 01-APR-1988; Project End 31-MAR-2007 Summary: (provided by applicant) Transplant patients sensitized to allo-Ag may undergo "accelerated" rejection (AccR), which combines cell and humoral immune mechanisms. We have developed a model of cardiac allograft rejection in skin sensitized mice (B/c- B6; rejection in <36h). We will study the role and mechanisms of CD154CD4O T cell costimulation in host sensitization. These studies are important for: (i) further understanding the allograft rejection cascade in sensitized hosts; and (ii) defining novel mechanisms that may improve the long-term effects of CD154 blockade. We propose the following specific aims: (1). Analyze mechanisms by which CD154 blockade prevents AccR. Hypothesis: Inhibition of CD8+ T cell activation represents the principal mechanism of the CD154 blockade in sensitized hosts. First, we will use 2C TCR Tg system to dissect the mechanisms by which CD154 blockade prevents CD8+ T cell activation in sensitized hosts. Then, to test the functional significance of CD8+ T cell defect, we will compare the rejection process in sensitized WT hosts with or without CD4/CD8 effector branch depletion. Using T cell subsets or APCs alone or in combination from WT mice will test the restoration of graft rejection in CD154 KO recipients. We will determine whether activated CD8+ effectors (CD44high CD62Llow) alone can trigger accelerated rejection in naive CD154 KO hosts. We will delineate in vitro cross-talk between cell subsets after CD154 blockade that prevents CD8 T cell activation/differentiation. (2). Determine mechanisms by which CD1 54 blockade fails to prevent graft vasculopathy leading to chronic rejection. Hypothesis: Long-term allograft survival after CD154 blockade may be impaired by: (i) CD4-dependent afloreactive B cells, andior (ii) CD154-resistant or preexisting memory CD8 T cells. First, we will analyze serum alloreactive Ab levels and intragraft Ab deposition. The functional role of anti-donor Abs will be assessed in passive transfer studies (SCID). Then, we will determine the function of alloreactive B cells in vitro (ELISPOT) and in vivo (CD154 blockade in WT vs. B cell KO mice). The requirement of CD4 help for alloreactive B cells will be addressed in CD4 KO/CD4 mAbtreated WT mice. In parallel, we will study activation of resistant CD8+ and preexisting memory CD8+(CD44high CD62Llow T cells during the C0154 blockade by using GM1 marker and 2C ICR Tg system, respectively. (3). Investigate STAT4 vs STAT6 mediated mechanisms and the role of regulatory CD4+ T cells in CD154 blockade. Hypothesis: STAT6 signaling is important for the generation of regulatory CD4+ T cells to inhibit alloreactive residual CD8+ T and B cell responses after CD154 blockade. We will analyze the ability of CD154 blockade to affect early/ late allograft loss in WT, STAT4 vs. STAT6 KO mice. Proliferation, differentiation, and cytokine production by CD4+ and CD8+ I cells will be examined. We will establish the identity of regulatory CD4+ T cells, and determine their function in adoptive transfer experiments. STAT6-dependent mechanism will be further delineated after administration of regulatory CD4+ T cells into: (i) WT host + neutralizing lL-4/IL-10 mAb, and (ii) untreated STAT4 KO or STAT6 KO test mice.

The application plans detailed examination of the allograft and lymphoid tissues in recipient mice using conventional morphologic examination, a series of immunohistochemical studies using monoclonal antibody staining, an extensive panel of in situ hybridization studies focused on cytokine gene expression, and correlative analysis of cytokine gene expression using QC-RT-PCR. The primary system for analysis will be adoptive transfer of CD4 positive T cells with single antigen-specificity into immunodeficent syngeneic mice, such as SCID or rag knockout animals, that are transplanted with an alloantigenic cardiac graft. The first specific aim is to determine whether the mechanisms of rejection vary dependent on cytokine expression pattern and TCR-specificity and avidity in adoptive transfers of T cells into transplanted mice. Both T cell clones and TCR-transgenic T cells using alloreactive TCRs will be used for these studies. The roles of precise TCR specificity in the cytokine gene expression pattern by particular T cells can be distinguished using adoptive transfer of TCR transgenic cells differentiated in vitro into distinct functional subsets. The second specific aim is to produce several transgenic mice which express an immunoregulatory molecule under the control of a cardiac-specific promoter to probe the role of the allograft histological microenvironment on the progress of the immune response mediated by different kinds of T cells.

Project Title: DEFINING THE MECHANISM OF DELAYED XENOGRAFT REJECTION Principal Investigator & Institution: Chong, Anita S.; Associate Professor; Rush University Medical Center Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 01-JUN-1999; Project End 31-AUG-2002 Summary: (adapted from the applicant's abstract) The inadequate supply of human organs has created a strong interest in the use of non- primate organs for clinical transplantation, but vigorous immune reactions prevent their current use in humans. Recent genetic approaches have generated porcine organs that are significantly resistant to complement-mediated hyperacute rejection. Nonetheless, they elicit a significant immune response in primates or humans and are ultimately rejected in a process labeled delayed xenograft rejection (DXR) or acute vascular rejection (AVR). DXR/AVR is predominantly mediated by xenoreactive antibodies (XAbs) that bind to and cause endothelial cell activation in the xenograft. Remarkably, the natural and the elicited XAbs that mediate the rejection of porcine grafts in human and Old World monkeys are directed predominantly against a single carbohydrate epitope, galactose-alpha1,3galactose (alphaGal). Opportunities to study the immunological basis of anti-alphaGal antibody production in a xenotransplantation setting have been limited, historically, to humans and Old World monkeys, since all other mammals do not make anti-alphaGal Abs. However, the recent generation of alpha1,3galactosyltransferase knockout (GT-KO) mice, which do not express the alphaGal epitope and can spontaneously make antialphaGal Abs, has provided a new model system for a reductionist approach to studying alphaGal-mediated xenotransplant rejection. Using these mice, the investigators propose (1) to use in vivo and ex vivo approaches to define the B cell subsets producing natural and elicited anti-alphaGal Ab responses; (2) to define the role of cytokines in regulating anti-alphaGal Ab responses and xenograft rejection; and (3) to control anti-alphaGal Ab responses and xenograft rejection using pharmacological and biological immunosuppressants, then use in vivo and ex vivo approaches to define the immunological basis for the successful control. The investigators propose that these studies will lead to an improved understanding of the immune regulation of antialphaGal responses and of xenograft rejection, and ultimately to the development of new genetic and/or immunosuppressive strategies that allow xenografts to survive and function in humans.

Heart Transplant
Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2004 Summary: (provided by applicant): Acute allograft rejection occurs mainly because recipient T lymphocytes mount a vigorous specific immune reaction against donor allogeneic (allo) antigens (Ag). DC are the professional Ag presenting cells (APC) that as "passenger leukocytes" present the allo-Ag to recipient naive T cells and trigger graft rejection. However, DC are also involved in the induction/maintenance of Ag-specific self-tolerance. There is evidence that certain APC (macrophages and likely DC) increase production of the immunoregulatory cytokines interleukin (IL)-10 and transforming growth factor (TGF)beta1 after ingestion of apoptotic bodies. We propose to test the hypothesis that recipient DC, after interaction with donor major histocompatibility complex (MHC)+ apoptotic bodies in the appropriate extracellular environment, are able to generate T cells with regulatory function. We propose to employ this approach to induce Ag-specific tolerance in heart allograft recipients as an alternative to pharmacological treatments that induce generalized immunosuppression and severe side effects. To reach these goals we propose the following aims. AIM 1: To investigate the effect of apoptotic bodies on the phenotype, synthesis of cytokines, and T helper (Th)-driving capacity of DC in vitro. We will develop a phagocytosis assay of apoptotic bodies for mouse DC to analyze the phenomenon and molecules involved. We will analyze the phenotype and pattern of cytokines synthesized by DC under such conditions and the impact on the subset of Th lymphocytes induced. AIM 2: To characterize the T cell stimulator's function and the Th-driving capacity in vivo of DC exposed to apoptotic bodies. Our purpose is to learn how DC exposed to apoptotic bodies can regulate, in vivo, the outcome of a T cell response from Ag-specific immune reactivity to potential Ag-specific tolerance. AIM 3: To evaluate the effect of recipient DC exposed to donor MHC+ apoptotic bodies on heart allograft survival. After focusing on the influence of DC exposed to apoptotic bodies on alloimmune responses in normal hosts, we will investigate their role in allogeneic heart graft recipients. The results may provide new insight into how apoptotic bodies can modulate the Th-driving capacity of DC and determine the therapeutic potential of DC and apoptotic bodies in transplant tolerance.

Project Title: DONOR CELL FACILITATION OF TOLERANCE Principal Investigator & Institution: Strober, Samuel; Professor of Medicine; Medicine; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 15-MAR-1995; Project End 31-MAY-2005 Summary: (Adapted from the Investigator's abstract): In the first four years of this project, the investigators have shown that rat ACI vascularized heart allografts are accepted by Lewis hosts with a combination of TLI, ATG, and intravenous injections of donor cells. With one model, the results showed that donor cells, such as monocytes and dendritic cell precursors, with surface expression of class II MHC molecules but with incomplete expression of co-stimulatory molecules such as B7-1 and B7-2, were potent facilitators of nonchimeric tolerance, based on immune deviation rather than on clonal anergy or clonal deletion. In a second model, donor cell infusions containing hematopoietic stem cells, such as bone marrow, were potent facilitators of chimeric tolerance, which was best explained by clonal anergy or deletion. Tolerance required both an alteration of the host immune system by the preparatory regimen and the injection of an appropriate donor cell population in both models. Additional data show that NK1.1+ T-cells are an important component of the host tolerance response. In particular, these cells seem to be important for the production of IL-4 that is required for

tolerance. The studies proposed here will test the hypothesis that TLI causes an increase in NK1.1+ T-cells, such that they become the predominant subset of T-cells in the spleen; that activation of the host NK1.1+ T-cells, and their secretion of IL-4, is required for the induction of tolerance; and that donor cells that facilitate tolerance activate host NK1.1+ T-cells by donor cell expression of CD1. In order to test the hypothesis further, they will use mice that lack NK1.1+ T-cells (CD1 or Jalpha281 KO) or lack specific cytokines (IL-4 KO, IL-10 KO, IFNgamma KO). In addition, they will use donor mice that lack specific antigen presenting molecules (CD1 KO, MHC Class II KO). They propose to study the role of NK1.1+ T-cells and their IL-4 secretion in tolerance by TLI, TLI plus ATG, and a depleting anti-CD4 mAb in a heart transplant model. They will also study GVHD using similar hypotheses and models. Mice tolerant of their allografts will be observed for evidence of immune deviation, clonal anergy or deletion, chimerism, and allograft expression of cytokine mRNA.

Project Title: DONOR-SPECIFIC T CELL MEMORY: BARRIER TO TOLERANCE Principal Investigator & Institution: Pearson, Thomas C.; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): Transplantation has emerged as the preferred method of treatment for many forms of end-stage organ failure. While short-term results have, improved long-term outcomes remain inadequate. The development of strategies to promote the long-term acceptance of allogeneic tissues without the need for chronic immunosuppression, which defines transplantation tolerance, could greatly expand the application of organ, tissue and cellular transplantation for diseases such as the hemoglobinopathies, genetic immunodeficiencies, and possibly autoimmune diseases. However, transplantation tolerance has remained an elusive goal in clinical transplantation. It has been known for many years that mixed hematopoietic chimerism induces a state of specific immunological tolerance, and in recent years it has been shown that this goal can be achieved in mouse models using clinically relevant costimulation blockade based strategies. While there are many practical issues that must be addressed for tolerance induction to become a clinical reality, we believe that the strategy must provide a means to control the existing population of donor-specific T cells in the periphery. This includes the control of memory cells that may persist in an individual as a result of previous antigen exposure. An understanding of the memory cell population is critical; both to prevent these cells from being a barrier to tolerance induction, as well as maintaining their function posttolerance induction to prevent infectious complications in transplant recipients. The specific aims of this study are to: (1) To characterize the number, distribution, phenotype and function of allospecific memory T cell subsets generated after skin or cardiac transplantation in the mouse; (2) To determine the number, subset and phenotype of allospecific memory T cells that prevents, the induction of chimerism and tolerance using the CD2B/CD40 blockade and micro-conditioning tolerance induction protocol; (3) To define strategies to tolerize allospecific CD4 and CDB memory populations by (a) blockade of alternative costimulatory pathways, or (2) manipulation of the signal 3 pathway. The results of this study will be critical for the development of safe strategies for the induction of transplantation tolerance to address the great clinical need.

Principal Investigator & Institution: Villanueva, Flordeliza S.; Medicine; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-AUG-1997; Project End 30-JUN-2006 Summary: (provided by applicant): Coronary artery disease is the major cause of mortality in the United States. Although many patients come to medical attention because of hemodynamically significant coronary lesions, over one-half who die suddenly from coronary disease have had no pre-existing symptoms. It has been hypothesized that critical abnormalities in the coronary endothelial lining provide a milieu that ultimately promotes acute thrombotic occlusion in the absence of significant prior coronary stenoses. Moreover, in patients with angina due to severe stenoses, endothelial abnormalities likewise promote the development and progression of atherosclerotic plaques that culminate in acute ischemic syndromes. Aberrations in endothelial function in coronary disease involve the microcirculation and occur in other cardiovascular disease states such as heart transplant rejection and ischemiareperfusion. Endothelial dysfunction is thus a critical mediator of the total burden of atherosclerotic heart disease and a major component of other cardiovascular pathologies, and the identification and treatment of this phenomenon would confer significant health benefits. Unfortunately, methods to identify patients with early endothelial dysfunction are limited. Studies have shown that endothelial overexpression of leukocyte adhesion molecules such as intercellular adhesion mnolecule-1 (ICAM1) promotes the development of the earliest lesions of atherosclerosis, suggesting that ICAM1 can serve as a marker of incipient endothelial disease. Using perfused cultured human coronary artery endothelial cells (ECs), we recently proved the principle that gas-filled microbubbles conjugated to a ligand that binds specifically to ICAM1 adhere to interleukin1a-activated ECs overexpressing ICAM1. Because these bubbles are acoustically active in the presence of ultrasound, we hypothesize that in vivo ultrasound imaging of bubbles targeted to specific cell surface markers of endothelial activation such as ICAM1 will permit non-invasive identification of pre-clinical endothelial dysfunction. To test this hypothesis, in vitro and in vivo models of endothelial activation will be used to address three Specific Aims with respect to bubbles engineered to bind to cell surface markers of endothelial disease: (1) Define shear conditions under which ICAM1-targeted bubbles attach to ECs and optimize bubble characteristics for binding; (2) Identify other EC surface proteins specific for endothelial dysfunction, including selectins, vascular adhesion molecule-1, or vascular endothelial growth factor receptors, evaluate their suitability as imaging targets, and design microbubbles for these targets; and (3) Image and quantify targeted bubble adhesion in vivo under clinically relevant conditions. The ultimate goal of this proposal is to develop targeted ultrasound imaging in order to enhance the early diagnosis of ischemic heart disease or other cardiovascular disease states associated with endothelial dysfunction. Principles gleaned from these studies can be extended to function-specific ultrasound imaging of other targets such as angiogenic markers, and may also provide a basis for targeted therapeutic approaches using microbubble carriers.

Summary: Elevated homocysteine (Hcy) in the blood is an established risk factor for cardiovascular disease. Increases in dietary folate and B6 have been shown to lower Hcy levels. There are however, certain groups with other health problems where Hcy remains elevated, these include heart transplant recipients, diabetics, women with preclampsia or retarded fetal growth, end stage renal disease and Parkinson's disease. The aim of this proposal is to elucidate how nutritional insufficiency of folate and B6 affect the pathways of Hcy metabolism in mammalian cells. There are four specific aims: (1) the development of rapid enzyme-based assays for 5,10-methyleneTHF, B6 vitamers and homocysteine; (2) to determine the direction of flux of 1-carbon (1-C) groups in the cytosol and mitochondria of cells in culture, with special emphasis on serine hydroxmethyltransferase (SHMT); (3) to determine the role of mitochondria in the supply of 1-C groups to the cytosol; and (4) to determine the relationship of folate pools and metabolic levels of homocysteine with several different cell lines when either folate or B6 are limiting growth factors. Three hypotheses will be tested, which are: (1) that the role of cytosolic SHMT is not to generate 1-C units but to regulate the levels of glycine and 5,10-methyleneTHF in the cytosol; (2) that 1-C groups used by the cytosol are generated by the mitochondria as formate; and (3) Hcy levels are related to the level of 5,10-methyleneTHF in the cytosol.

Project Title: FAS LIGAND+ BLOOD CELLS TO REDUCE TRANSPLANT REJECTION Principal Investigator & Institution: Civin, Curt I.; Professor of Cancer Research; Oncology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant): The ability to stably transduce lymphohematopoietic stem-progenitor cells (HSCs) and progeny cells allows us to genetically engineer HSCs and progeny, especially dendritic cells (DCs), to serve as cellular tools to improve transplantation. Allogeneic (allo) blood and marrow transplantation (BMT) will continue to be an important treatment option in patients with many inherited and acquired diseases. Our recent Preliminary Results indicate that ex vivo or in vivo treatment with transduced FasL+ allog mouse DCs or HSCs suppressed the response to that alloantigen and increased engraftment of allo cells, without immunoablation or evident toxicity to the recipient mice. In Aims 1-2 of this proposal, we propose studies to test the concept and elucidate the principal mechanisms by which transduced DCs or HSCs constitutively expressing Fas ligand (FasL) appear to reduce the T (and NK) cells that mediate graft rejection without overwhelming organ toxicity or general immunologic impairment. Aims 1-2 attempt to accelerate and enhance the natural homeostatic role of FasL during the course of the alloimmune response, with the potential outcome that alloimmune T cells may be killed earlier in their activation/expansion, or killed more potently later during activation-induced cell death (AICD), by transduced FasL+ DCs (Aim 1) or HSCs/progeny (Aim 2), respectively. As we investigate this, we will examine the apoptotic pathways in alloimmune cells. In addition, since we expect that transduced FasL+ HSCs might potentially be toxic in vivo, we will in parallel investigate technologies to limit potential FasL toxicity, eg by transducing only a small percent of high quality HSCs, by employing a FasL deletion mutant that cannot be cleaved to release soluble FasL (sFasL), by eliminating the transduced cells themselves or their FasL expression after tolerance to HSCs has been generated, or by using lineage/stage-specific promoters to restrict FasL expression. A novel FasL+ cell therapy approach to reduce graft rejection may

eventually be used in clinical allo BMT. Furthermore, achievement of stable lymphohematopoietic chimerism would also be predicted to generate tolerance for transplanted allo organs or pluripotent stem cells. Therefore, in Aim 3, we will assess tolerance to cardiac allografts in hematopoietic macro-chimeras, generated by this FasL strategy, with or without other immunosuppressive methodologies such as costimulatory blockade. SPECIFIC AIM 1: Assess whether FasL+ DCs specifically reduce an alloimmune response and enhance engraftment of allo HSCs SPECIFIC AIM 2: Determine whether FasL+ HSCs generate specific tolerance in allo BMT. SPECIFIC AIM 3: Evaluate tolerance to cardiac allografts in hematopoietic chimeras generated using FasL+ DCs/HSCs. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: FUEL CELL POWER PACKS FOR LEFT VENTRICULAR ASSIST DEVICE Principal Investigator & Institution: Sarangapani, Srinivasan; Vice President; Innovative Chemical/Environmental Tech Environmental Technologies, Inc Norwood, Ma 02062 Timing: Fiscal Year 2002; Project Start 01-AUG-1998; Project End 30-JUN-2004 Summary: (Unedited Applicant's Abstract):The end-stage cardiac patients, who cannot undergo heart transplantation owing to age limitation, lack of donor hearts or complications in using immunosuppressive drugs are essentially salvaged by LVAD and TAH devices. An estimated 40-70,000 American cardiovascular patients under age 65 could benefit from a heart transplant each year, whereas only 2,400 patients actually receive such transplants. These patients can benefit from the LVAD type devices both as a bridge to transplant as well as an alternative treatment option. Of the -900 patients who have received the LVAD system, a growing number are surpassing the three-yearmark of continuous support with their LVAD device. With such growing number of people on LVAD, there is a need for a reliable power system that could support the devices for longer hours without interruption. In Phase I program, we demonstrated the feasibility of producing a low fuel cell stack assembly, weighing -225 g and stack volume of 0.19 L. The performance of single cell matched those of the state-of-the-art while some performance degradation was observed when single cells were assembled into a stack. The cause for such degradation has been identified and since corrected. The Phase II proposal concentrates on the engineering development of the power pack. Further weight/volume reduction, heat and water management issues, optimization of the membrane electrode assemblies, evaluation of the hydrogen source, failure analysis and initial hazard analysis are the objectives of the Phase II program. At the end of Phase II, a prototype unit with integrated hydrogen storage will be fabricated and tested at the Artificial Organ Development Center of the University of Pittsburgh.

27
dysfunction due to recipient pulmonary hypertension) and allograft vasculopathy are major causes of cardiac transplant failure. Understanding signaling mechanisms may be important to improve graft function and survival. Signaling through G-protein coupled receptors (GPCR), especially BAR, is important for normal cardiac and vascular smooth muscle cell physiology. BAR signaling is often compromised in the transplanted human heart, and several agents implicated in allograft vasculopathy can signal through G proteins. Transgenic mice have been developed with altered BAR and G protein signaling, including mice in which BAR-kinase (BARK1) is overexpressed. Increased expression of a BARK1 inhibitor improves cardiac performance in heart failure and transplant models. The plans are to use viral-mediated gene transfer in rat and rabbit models and transgenic mice models to investigate mechanisms by which GPCR signaling affects graft function. The Aims are (1) to characterize BAR signalling in brain dead rabbit hearts and to try to improve function with adenoviral delivery of BAR signalling/inhibitory molecules; (2) to characterize BAR signalling and elucidate molecular defects in murine cardiac grafts, to use transgenic BAR signaling mutants to determine effects on graft function, and to use a rabbit model of heterotopic cardiac transplantation to study the effects of acutely manipulating BAR signalling; (3) to use a pulmonary artery banding model in rabbits to produce RV stress, as a condition to test BAR signalling and as a means to improve posttransplant RV dysfunction; and (4) to study the role of G protein signalling in mediating vascular smooth muscle (VSM) cell proliferation, and to use a rat aortic allograft model to test strategies to limit VSM hyperplasia in transplantation.

Project Title: GENETIC DETERMINATION OF ALLOGRAFT VASCULOPATHY Principal Investigator & Institution: Benza, Raymond L.; Medicine; University of Alabama at Birmingham Uab Station Birmingham, Al 35294 Timing: Fiscal Year 2002; Project Start 01-JAN-1998; Project End 31-DEC-2002 Summary: (Adapted from applicants' abstract) Dr. Benza will become an Assistant Professor of Medicine in April 1997, in the Division Cardiovascular Diseases (DCD) at the University of Alabama (UAB). Dr. Benza's subspecialty training is in the area of Cardiac Transplantation with a research interest in vascular biology. He has won several distinguished departmental awards for his research in endothelial cell-mediated fibrinolysis and has presented his research at several national and international meetings. He received an American Heart Association/Alabama Affiliate Award during his first year of fellowship to fund his work in endothelial cell-mediated fibrinolysis and has several publications in peer reviewed journals. His proposed studies will define the relationship between impaired fibrinolytic activity and the development of cardiac allograft vasculopathy (Tx CAD), a frequent and costly problem post transplantation. The premise of these studies is that the development of Tx CAD may be related to the presence of certain fibrinolytic protein (t-PA, PAI-1, u-PA) gene polymorphisms (FPGP) in both the donor graft and recipient. Specifically, the expression of these genes may be affected in a genotype-specific manner by certain factors (hypertriglyceridemia) which develop as a result of the transplant. This altered expression of fibrinolytic proteins (FPs) will then lead to fibrin deposition and the development of Tx CAD analogous to the development of native CAD. In this context, FPGPs for t-PA, PAI-1, u-PA and fibrinogen will be determined by Southern blot and PCR techniques for 150 donor/recipient pairs. These patients will then be followed for a period of 4 years to determine if these FPGP are predictive for the development of Tx CAD. In addition, plasma levels (recipient) and tissue levels (biopsy specimens) of FPs will be determined

by ELISA and immuncytochemical fluorescent staining, respectively, to determine whether a link exists between the expression of these proteins, fibrinolytic genotypes and TX CAD. UAB, Department of Medicine and DCD will provide the research space, facilities, resources (secretarial support and office space) and appropriate time commitment (80%) to allow the candidate to conduct and accomplish the research goals set forth in this application. He will have no administrative or teaching duties during the period of this application. If his faculty mentor were to leave the institution, a new mentor will be appointed and his continued development toward becoming a independent physician scientist supported and encouraged.

While it is clear that CD4 + T cells responding through the indirect pathway participate in graft rejection, the presence and contribution of indirectly primed CD8 T cells to allograft rejection has not been addressed. We hypothesize that placement of an allogeneic transplant indirectly primes CD8 T cells, that these T cells comprise a significant portion of the indirect alloimmune response and that they migrate to the target organ. We further hypothesize that indirectly primed CD8 T cells contribute to the pathologic destruction of the transplanted organ through local effects at the graft site and by influencing the development of the remainder of the alloimmune T cell repertoire. We will test this hypothesis through the following specific aims. Aim 1. To compare the induction of the indirect CD8+ T call repertoire with the other components of the alloreactive T cell response to allografts. In these studies we will use complementary approaches to determine the contribution of indirectly primed CD8 T cells to the peripheral and intragraft alloimmune repertoire following skin or heart transplantation. Aim 2. To define the in vivo effector functions of indirectly primed CD8 T cells. In these studies we will use skin graft and heart transplant models to determine the in vivo effector functions and mechanisms of indirectly primed CD8 T cells and to fully assess their ability to mediate and/or contribute to graft pathology. Aim 3. To determine the in vivo requirements for indirect priming of CD8 T cells to transplant antigens. This aim will address the cellular and costimulatory requirements for priming CD8 T cells through the indirect pathway in vivo and will assess how eostimulatory blockade based interventions affect the function of these CD8 cells. The proposed studies will address an issue in transplantation immunology that has been ignored--whether and how indirectly primed CD8 T cells contribute to organ rejection. The design of effective therapies aimed at preventing rejection and improving human allograft survival depend on a complete understanding of the recipient alloimmune response. The findings derived from the work will define the role for indirectly primed CD8 T cells in allograft rejection and have the potential to guide future therapies aimed a prolonging graft survival.

Project Title: IMMUNE REGULATION IN LUNG TRANSPLANTATION Principal Investigator & Institution: Burlingham, William J.; Associate Professor; Surgery; University of Wisconsin Madison 750 University Ave Madison, Wi 53706 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 30-JUN-2004 Summary: Adapted from Investigator's abstract): Rapamycin inhibits obliterative fibrosis in a rat tracheal transplant model and promotes tolerance induction in mouse heart transplant models. Because it can spare the use of calcineurin inhibitors, rapamycin also promises to help eliminate the numerous side effects of cyclosporine and FK506. An ongoing multi-center, prospective, randomized, double-blinded clinical trial including patients from the UW-Madison is underway to see if a form of rapamycin (RAD) can prevent bronchiolitis obliterans syndrome (BOS) while improving long-term outcome in lung transplants. The clinical trial sponsored by Novartis relies on biopsy histology and pulmonary function tests to determine the primary endpoints; no immune function tests are funded. This proposal addresses not only surrogate markers of disease and therapeutic effects, but also aims, for the first time, to provide useful surrogate markers for the dynamic process of development and maintenance of allograft tolerance. We believe that such markers are essential for rational adjustment of maintenance immune suppressive therapy in a given patient. We also believe that tolerance is the best solution to the long-term problem of allograft obliterative airway disease, a problem that currently affects virtually all lung transplants. Specifically we will: 1) monitor the development of both systemic and local immune regulation of delayed type hypersensitivity (DTH) responses in all UW/Madison lung transplant recipients, including those receiving RAD-based vs. conventional IS therapy; 2) monitor the systemic and local release of soluble forms of donor HLA antigen in lung transplant patients, determine which soluble donor HLA antigens can trigger regulation of DTH, and analyze the role of metalloproteinase therein; and 3) monitor the persistence of donor T cells (including CMV-specific CD8+ cells), and alveolar macrophages, using flow cytometry of BAL cells. This research project will be conducted in conjunction with the current clinical trial, but will not exclude any lung transplant patients not enrolled in the trial. Our study has a high likelihood of providing clinical correlation of outcomes (acute & chronic rejection, infection) with surrogate markers of tolerance, alloreactivity and pathogen reactivity. We will determine how the sensitivity, specificity, and predictive value of each test would be clinically useful in the management of lung transplant patients.

Heart Transplant
Summary: (provided by applicant): The long term success of cardiac transplantation is currently limited by the high incidence of coronary artery disease, a manifestation of chronic rejection. This complication is principally related to antecedent episodes of high grade allograft rejection and/or ongoing alloreactivity. Daclizumab, a humanized antiCD25 antibody has been added to conventional immunosuppression to block and delete alloreactive T cells which express the high affinity IL-2 receptor alpha, CD25. At low doses this antibody prevents rejection in some but not all patients, suggesting that higher doses may be necessary particularly for poorly matched recipients who are at increased risk of rejection. However, Daclizumab may affect, not only the population of CD25+ alloreactive T helper cells (TH) but also the population of CD25+ regulatory/suppressor T cells which are believed to be crucial to allograft survival. The overall goal of this project is to study the mechanism which determines whether a graft will be rejected or tolerated and to develop a reliable strategy for tailoring the type and amount of immunosuppression to the patient's needs. The specific aims are: (1) To evaluate the frequency and characteristics of allospecific helper, cytotoxic and regulatory/suppressor T cells in heart allograft recipients treated with conventional immunosuppressive therapy and without (n=53) or with high doses of Daclizumab (n=53). (2) To establish the relationship between T cell alloreactivity, antibody production, acute and chronic rejection (3) To examine whether Daclizumab at 2mg/kg can reduce the frequency of acute and chronic rejection. To meet these objectives we will characterize alloreactive T cells within the graft and periphery with respect to direct or indirect activity and cytokine production. The generation of suppressor and regulatory T cells will be monitored by flow cytometry and functional studies. Anti-HLA class I and II antibodies will be monitored using both lymphocytotoxicity and ELISA methods. Statistical analysis will be performed to determine the relationship between the observed immunological changes and rejection in patients treated with conventional immunosuppressive therapy and with or without high doses (2mg/kg) of Daclizumab.

Project Title: IMMUNOMODULATION BY MHC CLASS II PEPTIDES Principal Investigator & Institution: Murphy, Barbara T.; Associate Professor; Medicine; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: (Verbatim from the applicant's abstract) The success of improved graft survival over the last decade has heightened the awareness of the long-term complication of classical immunosuppression, hence focusing future research on the development on tolerogenic strategies. It has become apparent that peptides play a central role in determining T cell responses to alloantigen. This has lead to an increasing interest in the potential use of synthetic peptides to manipulate T cell responses to foreign antigen. Peptides derived from both polymorphic and non-polymorphic regions of the MHC have been shown to significantly impact allograft survival in animals models, and clinical trials using non-polymorphic MHC peptides in humans are currently underway. Our preliminary data demonstrates that non-polymorphic MHC class II derived peptides inhibit the proliferative response to autoantigen, and alloantigen presented by both direct and indirect pathways. These immunomodulatory effects are mediated through the deletion of antigen presenting cells and T cell unresponsiveness. We hypothesize that the inhibitory peptides mediate their effects through binding to MHC class II, disrupting the interaction of the TCR with the MHC+peptide complex and thereby modulating the immune response. The aims of the research proposal are to investigate the mechanism of action mediating the

31
immunomodulatory effects of these peptides and to determine their role in preventing allograft rejection. We will define the pathways leading to the induction of apoptosis in antigen presenting cells and determine the relative susceptibility of the different professional antigen presenting cells to deletion. T cell signaling patterns in unresponsiveness T cells will be investigated, and studies performed to determine whether the lack of T cell response to subsequent stimulation is mediated by anergy, deletion or immune deviation. The sequence specific nature of inhibition by the peptides will be evaluated by amino acid substitutions. Binding studies will performed to determine both the site of binding, and the relative binding affinity of the original and altered peptides. The ability of non-polymorphic MHC class II peptides to prolong allograft survival and induce tolerance will be evaluated in a mouse cardiac transplant model. Gene transfer of peptide constructs to cardiac allografts will be performed to investigate the benefits of local versus systemic delivery on graft survival. The mechanisms mediating long-term allograft survival will be investigated in vitro and in vivo. Peptides will be combined with other immunomodulators to develop novel tolerogenic strategies. These studies will help elucidate the potential role of MHC class II peptides in the prevention of transplant rejection and the induction of tolerance.

Project Title: INDUCIBLE NO SYNTHASE IN CARDIAC ALLOGRAFT REJECTION Principal Investigator & Institution: Cannon, Paul J.; Professor of Medicine (With Tenure); Medicine; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 01-MAY-1996; Project End 30-JUN-2003 Summary: (adapted from the applicant's abstract): The general objective of the proposed research in this renewal application is to investigate the role of the inducible isoform of nitric oxide synthase (iNOS) in the biochemistry and pathobiology of cardiac allograft rejection. The central hypothesis to be tested is that NO produced by iNOS in macrophages infiltrating the myocardium and in the cardiac myocytes augments the myocardial inflammation and contributes to the death of cardiac myocytes. We have demonstrated: 1) that iNOS mRNA, protein, and enzyme activity are induced in endothelial cells, infiltrating macrophages and cardiomyocytes in rejecting cardiac allografts, and 2) that iNOS induction is accompanied by impaired ventricular function and death of heart muscle cells which occurs both by necrosis and by apoptosis. We now propose to investigate mechanisms responsible for necrosis, apoptosis, and iNOS expression during heart transplant rejection. Aim #1 is to investigate, using cultured cardiomyocytes and rat and mouse heterotopic cardiac transplantation models, the hypothesis that activation of polyadenosine 5' -diphosphoribose synthetase (PARS) by nitric oxide contributes to the necrosis of cardiac myocytes in vitro and during cardiac allograft rejection. Aim #2 is to investigate the hypothesis that myocardial inflammation, necrosis and apoptosis during cardiac allograft rejection are ameliorated using mice as allograft donors and recipients that are unable to express iNOS (iNOS-ko mice). Aim#3 is to investigate the hypotheses that apoptosis of cardiomyocytes triggered by NO can be inhibited by sem-selective iNOS inhibitors, by transfection with Bcl-2, and by administration of caspase inhibitors. Aim #4 is to investigate the interplay between iNOS and COX-2 in modulating prostaglandin and thromboxane synthesis during cardiac allograft rejection, the role of CD154-CD40 interaction in the expression of iNOS and COX-2 in cardiomyocytes and the effect of COX-2 expression on cardiomyocyte apoptosis in cardiac allograft rejection. The proposed experiments may provide new insights concerning the role of iNOS in pathobiology and potential therapy of cardiac

Project Title: INTERLEUKIN-10 IMMUNOSUPPRESSION Principal Investigator & Institution: Bromberg, Jonathan S.; Surgical Director; Center for Gene Therapy & Molecular Medicine; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-FEB-2000; Project End 31-JAN-2005 Summary: (adapted from applicant's abstract): Interleukin-10 (IL-10) causes suppression or down modulation of T cell, B cell, and antigen presenting cell (APC) functions. However, cellular IL-10 (cIL-10), derived from mammalian cells, also has immunostimulatory properties. Conversely, viral IL-10 (vIL-10), encoded by the BCRF I open reading frame of the Epstein Barr virus, is almost exclusively immunosuppressive. The structural and physiological basis for these key characteristics and differences have not been defined. The applicant's preliminary data now demonstrate that a defined structural change can convert vIL-10 to cIL-10-like activity, or cIL-10 to vIL-10-like activity, by interchanging a single amino acid between the viral and cellular ligands. This structural change correlates with IL-10 binding to the previously described IL-10R1 chain and may correlate with the function of a newly described IL-10R2 chain. The applicant hypothesizes that cIL-10 and vIL-10 differentially bind IL-10 receptors, activate second messenger pathways, and induce immunosuppressive or immunostimulatory responses. Dr. Bromberg also hypothesizes that IL-10R1 and IL10R2 and/or their associated second messengers are differentially distributed on different cell types. He proposes that elucidation of these differences will increase understanding of how IL-10 regulates immunity and allow the manipulation of IL-10 responses for immunosuppressive therapy in transplantation. The specific aims of the proposed research are: 1) Demonstrate the structural basis of the binding to and activation of the IL-10R complex by IL-10 ligand constructs. Binding and competition assays will be performed between various cIL-10 and vIL-10 constructs and IL-10R1 and IL-10R2 chains. Additional studies will assay second messenger pathways through Western blotting and electrophoretic mobility shift assays for JAK-STAT activation. 2) Demonstrate the immunologic activity of IL-10 constructs on T cell, B cell, and APC function. The differential distribution of IL-10R1 and IL-10R2 on T, B, and APC subsets will also be characterized. 3) Demonstrate the in vivo immunological activity of IL-10 constructs in a transplant model. Gene transfer of IL-10 constructs to cardiac allograft will be performed and the effect on graft survival and immune activation of T, B, and APC functions evaluated.

Project Title: LIVER TRANSPLANTATION: THE ROLE OF DENDRITIC CELLS Principal Investigator & Institution: Thomson, Angus W.; Professor; Surgery; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-MAY-1996; Project End 30-NOV-2005 Summary: (adapted from the applicant's abstract): The precise role of donor dendritic cells in the inherent tolerogenicity of hepatic allografts remains unresolved. We have shown, however, that poorly stimulatory, immature liver dendritic cells, or dendritic cells whose co-stimulatory function is blocked, can strikingly enhance activationinduced death in allogeneic T cells. Moreover, infusion of such immature donor

dendritic cells plus co-stimulatory blockade augments apoptotic death of host immunoreactive T cells and markedly enhances graft survival. These data support our hypothesis that liver dendritic cells have potential to promote the development of tolerance in allogeneic recipients by mediating the apoptotic death of allospecific T cells. Aim 1 is to elucidate the role of apoptosis in the outcome of liver dendritic cellallogeneic T cells interactions and the factors that influence this activity. These studies will test whether myeloid and lymphoid dendritic cells exhibit functional differences in their interaction with T cells and whether they have equal potential to mediate apoptosis in activated T cells and whether Th1 and Th2 cells are equally susceptible. The role of critical co-stimulatory pathways and of IL-2 in the regulation of T cell death will be examined. Aim 2 will ascertain the death regulatory pathways that may determine T cell apoptosis by liver dendritic cells. Contribution of the Fas pathway and the role of TNF families, in particular TRAIL, will be examined. Cell survival factors and death resistance molecules will also be examined for the possible differential resistance of Th1/Th2 subsets to dendritic cell induced death. Aim 3 studies will examine the ability of liver dendritic cells to delete alloreactive cells in vivo and will examine factors that modulate this activity. These studies will involve quantitative assessment of proliferation and apoptosis of CD4 and CD8 T cells in vivo. The impact of blockade of specific co-stimulaory pathways and whether antigen specific T cells are deleted selectively will be ascertained. Finally, Aim 4 studies will assess and maximize the therapeutic potential of liver dendritic cell induced alloantigen-specific T cell apoptosis in organ transplant recipients. In these clinically-relevant studies, emphasis will be placed on targeting specific costimulatory pathways, including use of novel blocking agents. The results will provide new insight into how liver dendritic cells can modulate survival of alloreactive T cells, and determine the potential of donor dendritic cells to delete allospecific T cells to facilitate transplant tolerance.

Project Title: MACROPHAGES IN REMODELING AND REJECTION OF SOLID ORGAN TRANSPLANTS Principal Investigator & Institution: Marsh, Clay B.; Vice Chair for Research; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: This project will explore the role of macrophages in the pathogenesis of chronic in organ transplantation. We hypothesize that HLA class I and/or II antigens are expressed by cells in the graft serve as the ligand for anti- donor MHC antibodies to be deposited. We speculate that recipient macrophages are stimulated by these antibodies to produce and secreted TGF-beta that appears to be important in organ acceptance. Consistent with this hypothesis, we found that deposited IgG stimulates human monocytes to produce TGF-beta, although whether this TGF-beta is activated is not clear. Thus, we will seek to define how monocyte production of TGF-beta induced by deposited IgG is regulated, determine the biochemical pathways modulating this production, determine if these in vitro data apply to endomyocardial biopsies from patients with heart transplants and test "proof of concept" studies in animal models. This project will interact with the other two projects in the proposal in a manner that will provide additional opportunities for discovery. Through these studies we hope to define the molecular mechanisms by which monocytes, macrophages and IgG may facilitate the generation of chronic rejection in organ transplantation and define new molecular targets to direct new strategies.

Heart Transplant
Project Title: MECHANISMS OF ACCELERATED GRAFT ARTERIOSCLEROSIS Principal Investigator & Institution: Baldwin, William M.; Associate Professor; Pathology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 06-MAY-1997; Project End 31-MAR-2008 Summary: (provided by applicant): This multidisciplinary research program project is focused on chronic rejection of heart transplants. Although advances in immune suppression and improvements in the diagnosis and treatment of acute rejection and infection have improved the survival for heart transplant recipients the first year, longterm survival is limited by chronic rejection. The lesion that ultimately causes chronic rejection is accelerated graft arteriosclerosis (AGA). The only treatment currently available for AGA is retransplantation, but retransplantation entails increased patient risk, and it exacerbates the increasing shortage of donor hearts. Although the gross and microscopic features of AGA have been well characterized, the cellular and molecular mechanisms leading to AGA need to be determined. It is clear that AGA is a complex and multifactorial process. This program project focuses antigen-independent and antigen-dependent responses that causes of vascular injury leading to AGA. The 3 projects will investigate the following interactive mechanisms of vascular injury and response to injury: 1) complement and antibody-mediated injury; 2) regulation of Weibel-Palade body secretion by endothelial cells; and 3) granzyme B-induced proteolysis of smooth muscle cell targets. We hypothesize that these mechanisms occur in the initial phases of AGA and represent potential novel targets for intervention before AGA is irreversible. Each of the 3 projects makes use of the extensive clinical material from human cardiac transplant recipients in the Clinical/Pathology Core to verify experimental data from animal models developed in the Animal Core.

Project Title: MECHANISMS OF ALLOGRAFT TOLERANCE Principal Investigator & Institution: Orosz, Charles G.; Professor; Surgery; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2002; Project Start 01-JAN-1999; Project End 31-DEC-2003 Summary: Long-term allograft survival is readily achieved in murine cardiac allograft recipients, but very little is known about the mechanisms by which this allograft acceptance is induced or maintained. We have developed a testable, working paradigm of cardiac allograft acceptance. This paradigm holds that allograft acceptance involves immune processes that actively protect allografts. We believe that one manifestation of this alloprotective process, the phenomenon of linked antigen non-responsiveness, holds the key to understanding allograft acceptance. The proposed studies will investigate important aspects of the alloprotective responses that develop in allograft recipients. Specific Aim 1: To evaluate the contributions of three intriguing cell types to the initiation of allograft acceptance responses. These are addressed as the "memory hypothesis", the "gamma/delta hypothesis", and the "NKT hypothesis". In general, we will use cell transfer studies with SCID mice to determine the role of memory T cells, gammadeltaT cells or NKT cells in the generation of alloprotective activity, ie., linked DTH non-responsiveness or cardiac allograft acceptance. Specific Aim 2: To evaluate two non-competing mechanisms by which allograft acceptance is maintained. These are addressed as the "cytokine synergy hypothesis" and the "protected compartment hypothesis". In general, we will use cytokine knock-out mice and anti-cytokine antibodies to dissect the roles of TGFbeta, IL10 and IL4 in the expression of alloprotective activity (linked DTH non-responsiveness and cardiac allograft

acceptance). We will also determine whether new alloprotective mechanisms independent of these cytokines are installed in accepted allografts over time. Specific Aim 3: To identify the cytokine environment necessary for the in vitro generation of alloprotective T cells that can be transferred into allograft recipients to promote cardiac allograft acceptance. Initially, these studies will use IL10 to drive alloantigen- stimulated splenic T cells towards alloprotective behavior. Specific Aim 4: To evaluate and optimize the experimental system in which tolerization to BSA, a foreign protein unrelated to an allograft, can be used to promote linked non-responsiveness to graft alloantigens, and thus educate an allograft recipient toward allograft acceptance. This represents a novel therapeutic approach that uses BSA as a "vaccine" for transplant recipients. Routine molecular genetic methods would allow us to explore the potential of this vaccine strategy for use as a potential gene therapy in transplant recipients. Finally, we will evaluate the effects of concurrent infection with murine influenza virus on he survival of the graft and recipient in mice that are being educated with BSA for allograft acceptance.

Principal Investigator & Institution: Wasowska, Barbara A.; Pathology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 24-JUL-2000; Project End 30-JUN-2004 Summary: Numerous clinical observations indicate that in certain patients alloantibodies probably contribute to rejection. Although some investigators have attributed a causal relationship to this association, there are still insufficient data to evaluate critically the mechanisms of such antibody-mediated acute allograft injury. Presently, the availability of inbred "knock out" mice, monoclonal antibodies to critical mediators, and soluble recombinant receptors provide the means to establish a causative role of antibody in the in vivo pathogenesis of acute graft rejection. Recent in vitro studies have demonstrated that antibodies and complement can initiate dynamic interactions among endothelial cells, macrophages and platelets that are mediated by adhesion molecules and their ligands. The potential role of these receptors and their ligands has not been examined in acute alloantibody-mediated rejection. The hypothesis to be tested in this proposal is that alloantibody and complement mediate acute cardiac rejection by activating endothelial cells, macrophages and platelets through ,expression of P-selectin and von Willebrand factor. The proposed studies are based upon our extensive preliminary data from cardiac allograft models in complement deficient rats as well as immunoglobulin knock out (IgKO), C4, C3 and CR2 KO mice. The specific aims of this project will test our hypothesis by demonstrating that: 1. Passive transfer of complement-activating classes and subclasses of mAbs specific for donor MHC antigens can reconstitute cardiac allograft rejection in IgKO mice and cause the upregulation of Pselectin, von Willebrand factor, and MCP-l in endothelial cells. 2. Passive transfer of non-complement-fixing subclasses of mAbs specific for donor MHC antigens will modulate in a dose-dependent manner cardiac allograft rejection induced in IgKO mice by complement-activating subclasses of mAbs with the same specificity. 3. Activation of endothelial cells, B-cells, platelets and macrophages by antibody mediated acute rejection is inhibited in C4, C3 and CR2 KO mice resulting in prolonged cardiac allograft survival. 4. P-selectin augments activation of endothelial cells, platelets and macrophages in allograft rejection. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: MESENCHYMAL PROGENITORS OF INTRAGRAFT FIBROBLAST Principal Investigator & Institution: Wu, Gordon D.; Children's Hospital Los Angeles 4650 Sunset Blvd Los Angeles, Ca 90027 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2004 Summary: Recent observations indicate that fibroblasts of recipient origin may actively participate in the development of chronic allograft rejection. Recipient-derived fibroblasts have been showed to contribute to fibrosis in human renal transplants as well as rodent heart allografts. These exciting findings could impact human health care in a positive way: if the progenitors of graft-proliferating fibroblasts are identified, new strategies aiming at inhibition of these cells will become possible for the treatment of chronic rejection. In order to appreciate this potential, the scientific community must determine the phenotype(s) of the mesenchymal stem cells (MSC) that give rise to intragraft fibroblasts, and must understand the mechanisms that control their homing to allografts. The central hypothesis for the research proposal is that proliferating intragrafl fibroblasts are derived from mesenchymal progenitors of host origin, which are committed de novo in the bone marrow, released into blood circulation, attracted by local factors to home to allograft during chronic rejection. Three Specific Aims will be pursued: (1) Identify the progenitor cells of intragrafl fibroblasts. The proliferative hierarchy of the fibroblastic lineage of MSC will be determined using MSC differentiation cultures, immunophenotyping and fibroblast functional assays. Vectormarked syngeneic MSCs of defined phenotype will then be engrafted into rat recipients of cardiac allograft for assessment of their capacity to home to allografts. Clonal integration analysis will determine if the progeny of vector-marked MSC is originated from the same precursor, or discrete stem cell. (2) Determine the mechanism that is responsible for the recruitment and proliferation of fibroblast progenitors in allografts. Studies are designed to test a hypothesis that homing of MSC to allograft is mediated by binding of CD44 expressed by the progenitors to extracellular matrix hyaluronan (HA); MCP-1 promotes MSC migration by up-regulating expression of selected CD44v isoforms and supports fibroblast proliferation by stimulating macrophage production of fibrogenic factors. (3) Determine the feasibility of using fibroblast progenitors as a vehicle for gene delivery to allografls. Mesenchymal progenitors will be transduced with retroviral vectors containing a hepatocyte growth factor (HGF) gene and then engrafted into allograft recipients. Studies are designed to examine the distribution of the engrafted MSC in allograft and bone marrow, kinetics of HGF production, its impact on bone marrow cell biology and the development of graft fibrosis. Our studies will provide definitive proof that mesenchymal progenitors of recipient origin play a pathogenic role in the development of graft fibrosis, and will determine the phenotype of fibroblast progenitors, the recruitment mechanism, and the feasibility of using MSC for gene therapy of chronic rejection.

Box 6508, Grants and Contracts Aurora, Co 800450508 Timing: Fiscal Year 2002; Project Start 01-JAN-2002; Project End 31-DEC-2005 Summary: This proposal addresses the molecular epidemiology of dilated cardiomyopathy by determining the frequency of disease gene mutations, and the genotype/phenotype correlations in the patient population, and their clinical relevance.
Studies
37
Idiopathic dilated cardiomyopathy (DCM) is a disease affecting the cardiac muscle and is a primary cause of heart failure leading to heart transplant. The etiology of DCM is mainly unknown, but the disease is frequently inherited and genetically heterogeneous. Linkage studies have identified 17 FDC disease loci including a locus mapped by the P.I.'s laboratory on chromosome 9 in a large kindred with autosomal dominant FDC. Thus far, 8 disease genes have been identified: the P.I.'s laboratory has contributed to the discovery of mutations in dystrophin gene leading to X-linked FDC, and more recently, has discovered lamin A/C gene mutations in patients with FDC and variable skeletal muscle involvement. Other investigators have reported mutations in cardiac actin, deltasarcoglycan, desmin, tafazzin, beta-myosin heavy chain and troponin T leading to FDC. However, the prevalence, type and clinical relevance of cytoskeletal gene mutations in FDC, and in the overall DCM population are unknown. This application proposes a series of experiments designed to test the following hypotheses: 1) gene mutations are a frequent cause of FDC, 2) different gene mutations may have different frequency, different prognostic value, and different clinical relevance, 3) several FDC genes are still unidentified, and they are likely to encode cytoskeletal proteins. The Specific Aims of this proposal are: 1) to investigate of a cohort of patients with FDC and to evaluate their relatives to determine the inheritance pattern, the phenotype, the natural history, and recruit for molecular genetics studies; 2) to identify and characterize novel genes causing FDC using a candidate gene approach and a positional candidate cloning approach; 3) to analyze the molecular epidemiology of known and novel disease genes by studying the prevalence, type, and genotype/phenotype correlation of the FDC gene mutations in a large patient population with or without a familial trait. Clinical data, DNA and, in the case of FDC, lymphoblastoid cell lines have already been collected from 478 subjects, and we anticipate the enrollment of 20 to 30 new families/year. The experimental methods include mutation screening of known and novel candidate genes, positional cloning of the FDC gene on chromosome 9 by linkage and association studies, analysis of the frequency and genotype/phenotype correlations using a large database designed for these studies. The identification of the genes and mutations responsible for DCM will greatly increase the understanding of the molecular basis of this disease and will allow for the development of new molecular- based diagnostic and therapeutic strategies.

We will examine the intracellular molecular mechanisms for the actions of excess NO on cardiac allograft contractile dyskinesis relating to a paradigm which includes both oxidative and nitrosative stress. We will examine the regulation of inducible NO synthase (iNOS) gene expression by the oxidant-sensitive NF-kB transcription factor and examine key candidate cytosolic and mitochondrial proteins as molecular targets of NO. These proteins include myoglobin and aconitase. In vitro nitrosylation of these proteins are known to inhibit enzyme activity and 02 binding, thus, interfering with efficient 02 utilization by this O2-demanding organ. Hypothesis: [NO derived from iNOS targets certain cellular proteins for nitrosylation within cardiac grafts that contribute to

Furthermore, reactive oxygen plays a role in regulating iNOS gene expression at the transcriptional level via activation of the oxidant-sensitive transcription factor (NF-KB).] The applicant will use advanced, stateof-the-art molecular and biophysical techniques including: transcription factor regulation of iNOS gene (gel shift assays; Northern and Western analysis); in situ sonomicrometry; measures of nitrosyl protein and function (EPR, electron paramagnetic resonance spectroscopy and immunoprecipitation); assay for apoptosis; quantitation of reactive oxygen (EPR spin trapping; salicylate trapping); evaluation with iNOS knockout and SOD1 or SOD2 transgenic mice. The applicant will show that following allogeneic cardiac transplantation: Aim #1: [Induction of iNOS leads to iron-nitrosyl complex formation within myocardium and contractile dysfunction during allogeneic cardiac transplantation.]; Aim #2: [Certain candidate proteins are molecular targets of nitrosylation by excess NO in allogeneic transplantation.]; Aim #3: [iNOS gene deletion prevents nitrosyiprotein formation and prolongs graft survival. ]; Aim #4: [iNOS gene expression during allogeneic transplantation is regulated by activation of NF-KB.]; Aim #5: [Antioxidants inhibit activation of NF-KB, induction of iNOS, formation of nitrosyl complexes and enhance contractile function.]; Aim #6: [Antioxidant transgene overexpression inhibits activation of NF-kB, induction of iNOS, formation of nitrosyl complexes and enhances contractile function during allogeneic cardiac transplantion.] These studies will provide a novel mechanism to explain the pathogenesis of dyskinesis and graft failure during cardiac transplant rejection.

Principal Investigator & Institution: Strauch, Arthur R.; Professor; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: Chronic rejection in the transplanted heart is associated with interstitial fibrosis and progressive neointimal lesion formation in the coronary arterial bed that impairs tissue perfusion to the point of functional disruption. Our intention in Project 3 is to examine wound repair processes in the transplanted heart that specifically involve activated stromal myofibroblasts. We propose that alloantigen-independent ischemia/reperfusion injury during the early post-operative period as well as chronic, alloantigen-dependent release of TGFbeta1 in long-term accepted grafts promote myofibroblasts activation and histogenic remodeling via a common signaling pathways based on reactive oxygen species (ROS). Myofibroblasts accumulate in the coronary adventitia and cardiac interstitium of heart grafts where they express several injuryresponse genes that are regulated by MSYI, a cold-shock domain (CSD) transcriptional regulatory protein. MSY1 and related proteins are important mediators of the transcriptional response to tissue stress and redox imbalance. The goal of the proposed research is to examine TGFbeta1- and ROS-dependent changes in MSY1 protein complexes that govern VSM alpha-actin promoter activity. Mis-regulation of VSM alpha-actin expression during chronic rejection is associated with accumulation of myofibroblasts, fibrocontractile scar tissue, neointimal smooth muscle cells, and poorly differentiated cardiomyocytes. VSM alpha-actin is encoded by a prototypical injury response gene that shares MSY1 control elements with other genes required for wound repair. Analysis of interactions between MSY1 and other TRPs required for injuryresponse gene expression in human stromal myofibroblasts should provide new information about molecular control points in chronic rejection. In human pathology

and intramyocardial biopsy samples, assessment of MSY1:TRP structure and function may provide new prognostic indicators for evaluating and staging chronic rejection in transplant patients before the development of graft-destructive fibrosis. From the standpoint of transplant vascular sclerosis, studiers of stromal myofibroblasts are especially relevant given the demonstrated importance of adventitial fibroblasts in neointima formation as well as the establishment of new microvascular perfusion circuits that are critical for long-term heart graft survival. Finally, TGFbeta1 and/or ROS may modulate expression of other MSY1-dependent, chronic rejection- associated genes such as those encoding MHC class II molecules which compliments Project 1 and 2 aims pertaining to alloantibody production, monocyte/macrophage FcR engagement, and the role of TGFbeta1 in graft acceptance vs. fibrosis.

However, whether NF-kB is in fact necessary for CD28 and TCR-mediated functions in vitro and in vivo is not fully understood. The global aim of this study is to determine whether activation of NF-kB is necessary for defined T cell functions driven by ligation of TCR and CD28. Specific Aim 1. To determine whether activation of NF-kB is necessary and/or sufficient for CD28-mediated costimulation of T cells in vitro. We hypothesize that NF-kB activation is selectively required for a subset of T cell functions promoted by CD28 costimulation. To address this issue, T cells from 2 strains of mice deficient in NF-kB activation will be utilized. To address whether NF-kB activation is sufficient to bypass a need for CD28 costimulation, T cells from CAR transgenic mice will be transduced with an adenoviral construct expressing a constitutively active form of IKKb. In all cases, effects on T cell survival, cytokine production, and differentiation into effector cells will be examined. Specific Aim 2. To investigate whether lack of NF-kB activation prevents the lymphoproliferative disease observed in CTLA-4-deficient mice. CTLA-4, a molecule with marked homology with CD28, is a negative regulator of T cell responses that also inhibits NF-kB activation. We hypothesize that the lymphoproliferation occurring in CTLA-4-deficient mice is due, in part, to unopposed NF-kB activation in T cells. To address this possibility, CTLA-4-deficient mice will be interbred with mice expressing the IkBa transdominant gene on T cells, and life span, numbers of T cells in peripheral lymphoid organs and in solid organs, and T cell function will be monitored. Specific Aim 3. To determine whether NF-kB activation is necessary for acute allograft rejection. To address the requirement for NF-kB activation in acute allograft rejection, skin and heart allografts will be transplanted into mice with deficient NF-kB activation in T cells. Graft survival, T cell priming, migration, and effector function will be analyzed. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Principal Investigator & Institution: Webber, Steven A.; Pediatrics; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2004; Project Start 15-FEB-2004; Project End 31-JAN-2009 Summary: (provided by applicant): Over the last 15 years, significant improvements in patient outcome have occurred such that heart transplantation is now considered an established therapy with a high likelihood for short-term success. However, the emotional, financial, social and medical burdens placed on patients and families remain enormous and heart transplantation therapy remains palliative. Indeed, most children transplanted in infancy and childhood are not predicted to survive to adulthood. The immunosuppressive regimens have many inherent risks including infections, malignancy and multiple end-organ toxicities. Furthermore, these agents have had little impact on the development of chronic rejection, the leading cause of death late after transplantation. The central paradigm driving this integrated SCCOR proposal is that further improvements in clinical outcome following pediatric heart transplantation depend upon novel strategies that link basic science advances with evidence-driven modifications in clinical protocols. This SCCOR proposal will bring together experts in the fields of pediatric cardiology (cardiac transplantation) and cardiac surgery, immunology, infectious disease, molecular genetics, and biostatistics to advance the common goal of developing novel approaches to the management of pediatric heart transplant recipients. Our long-term goals are to: 1. Develop strategies that result in long-term graft acceptance without requiring immunosuppression. 2. Develop strategies to reduce the morbidities related to non-specific immunosuppressive protocols. 3. Identify genetic markers that predict disparities in transplant outcomes in children after transplantation, including racial disparities. 4. Develop non-invasive diagnostic strategies for rejection surveillance that reduce cost and improve quality and length of life. This Pediatric CV SCCOR proposal addresses each of these areas with novel, hypothesis driven projects to rapidly and significantly advance the state-of-the-art care for pediatric heart transplant recipients.

Project Title: OXIDATIVE STRESS SIGNALING IN GRAFT CORONARY DISEASE Principal Investigator & Institution: Robbins, Robert C.; Assistant Professor; Cardiothoracic Surgery; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2005 Summary: (Verbatim from the applicant's abstract) We propose to investigate the role that early myocardial oxadative stress signaling pathways have in the development of graft coronary artery disease (GCAD) following cardiac transplantation. In the established PVG donor to ACI recipient rat model, expression of bcl-2 decreases and nuclear factor kappa-B (NFkB) activity increases in the early reperfusion period. Inhibition of NFkB reduces reperfusion injury and GCAD in this model. In other models of ischemia and reperfusion BCL-2 has been shown to regulate NFkB activity. The overall hypothesis of this proposal is that myocardial oxidative stress following cardiac transplantation contributes to the development of graft coronary artery disease via a bcl2 associated mechanism. The specific aims of the proposed work are: 1) To delineate the dependence of early myocardial oxidative stress and NFkB activity on bcl-2 expression following cardiac transplantation; 2) To determine the effects of decreased or increased myocardial oxidative stress on bcl-2 expression and NFkB activity following cardiac

transplantation; and 3) To determine the role that early post-transplantation myocardial bcl-2 expression and intracellular localization plays in the later development of graft coronary artery disease. This proposal utilizes transgenic mice to more clearly characterize the role that bcl-2 plays in NFkB activation and in the development of myocardial oxidative stress following cardiac transplantation. The knowledge gained in the transgenic experiments will contribute to the overall understanding of the effects of bcl-2 overexpression on the development of GCAD in the PVG to ACI model. Upon completion of this study, we will have demonstrated the potential of altering the signaling pathways of oxidative stress by graft specific modulation, which may have applicability for other solid organ transplantation and as a myocardial protection strategy for routine cardiac surgical procedures.

Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 31-OCT-2004 Summary: Immune-mediated rejection is the principal obstacle to the use of heart transplantation for the treatment of end-stage cardiac failure. Current immunosuppressive regimens have limited efficacy and are associated with substantial toxicity. A recently discovered mechanism of inflammatory injury, the "Poly (ADPribose) Synthetase (PARS) Pathway", has now been implicated in the pathogenesis of allograft rejection. Triggered by peroxynitrite-induced DNA single strand breaks, PARS catalyzes an energy-consuming polymerization of ADP-ribose, resulting in NAD depletion, inhibition of glycolysis and mitochondrial respiration, and the ultimate reduction of intracellular high energy phosphates. PARS activation also strongly upregulates expression of the transcription expression of the transcription factor AP-1 and AP-1 dependent genes, including ICAM-1. In this proposal, we present experimental evidence that pharmacologic inhibition of PARS activity has potent anti-inflammatory effects and prolongs cardiac allograft survival. The specific aim of the present proposal has to determine the benefit of PJ-34, a novel, non-toxic, and highly potent PARS inhibitor, in the prevention of organ dysfunction and cellular injury in an experimental rodent model of cardiac transplant rejection. Demonstration that PJ-34 prevents tissue injury and prolongs graft survival would represent a breakthrough in the design of novel anti- inflammatory regimens to prolong allograft survival. PROPOSED COMMERCIAL APPLICATIONS: The domestic marker for a novel, effective therapy for cardiac allograft rejection is estimated at $100 million per annum. Global markets are estimated at $400 million. Current market entrants such as cyclosporine A and FK506, have substantial toxicity. Funding of SBIR Phases I and II would allow for market entry in 4 years. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

stimulation of the recipient s immune system leading to prevention of CR. An animal model as been developed to test this hypothesis. Animals are pretreated with donor bone marrow or a hepatic allograft in concert with Tacrolimus. Donor microchimerism persists for at least 100 days, and then, the animals are challenged with a heterotopic cardiac allograft (CCA). The PI has found that animals previously receiving a liver allograft do not experience CR while those that receive bone marrow do. The hypothesis is advanced that the liver provides the stromal elements for survival of donor hematopoietic stem cells which protect cardiac allografts from CR. In contrast, with animals receiving donor bone marrow, there is induction of a strong Th-1 type cell response due to a loss of microchimerism, which leads to CR. In this project, the PI proposes to study the mechanisms responsible for lymphocyte trafficking and cellular activation, the influence of persistent donor antigen presenting cells on the incidence and intensity of CR and whether maneuvers for augmentation of donor chimerism in human liver transplant patients lowers the severity of CR.

Principal Investigator & Institution: Libby, Peter; Chief, Cardiovascular Medicine; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-SEP-1990; Project End 30-SEP-2003 Summary: Transplantation-associated arteriosclerosis (TxAA) is an intimal fibroproliferative lesion composed predominantly of vascular smooth muscle cells and associated matrix proteins, admixed with mononuclear inflammatory cells. TxAA causes progressive, insidious vascular occlusion and results in allograft ischemia; it represents the major long-term limitation to solid organ transplantation. Although TxAA is largely ascribed to an immune- mediated allogeneic response, it occurs even in the setting of immunosuppression adequate to block acute parenchymal rejection, and does not correlate strictly with episodes or severity of allograft rejection. Thus, cytokine-induced endothelial dysfunction, recruitment and activation of antigen-non-specific cells, or antibody-mediated processes may modulate the development of TxAA. We have proposed that TxAA is due to a chronic delayed-type hypersensitivity response of host T cells to donor vascular wall cells, distinct from the cytolytic response characteristic of acute rejection. This chronic response persists in part because of incomplete elimination of relevant foreign antigens. Moreover, the initial immune-specific response triggers the release of antigen non-specific effectors such as macrophages and cytokine networks less susceptible to immune modulation. We propose here to continue our long-term objectives of unraveling the mechanisms by which specific effector cell subsets and cytokines initiate and promote TxAA. Using a murine heterotopic cardiac transplant model, Specific Aims of this proposal are: 1) Test the hypothesis that acute rejection and TxAA are mediated via distinct T cell subsets and cytokines. Mice genetically-deficient in particular cytokines or their receptors ("knock-outs"), as well as adoptive transfer methodology, will be used to evaluate the contribution of specific cell subsets (e.g., Thelper 1-type cells, B cells) and cytokines in either promoting or ameliorating acute rejection and TxAA. 2) Identify the mechanisms underlying our seminal observations that acute parenchymal rejection and allograft failure are accelerated in inteferon (GKO) recipients, while TxAA is completely abrogated in long-term allografts in GKO recipients. The observations point to distinct mechanisms mediating acute vs. chronic allograft pathologies, and suggest that different therapeutic interventions will be uniquely applicable to each.

Project Title: P-GLYCOPROTEIN FUNCTION IN ALLOGRAFT REJECTION Principal Investigator & Institution: Frank, Markus H.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2005 Summary: (provided by applicant): The applicant is a nephrologist with an interest in transplant immunology, who is eligible for and fulfills all the necessary requirements to be considered for a Mentored Clinical Scientist Award. As part of his nephrology fellowship at the Brigham and Women's Hospital and The Children's Hospital in Boston, the applicant completed 3 years of laboratory-based research during which he gained practical experience in techniques of cellular and molecular immunology. The main thrust of his research has been the study of the role of P-glycoprotein, the multidrug resistance-associated ABC transporter, in alloimmunity, and the principle findings are now being published in the Journal of Immunology. The applicant is now completing his nephrology fellowship and will be appointed as a staff member at the Brigham and Women's Hospital and as an Instructor of Medicine at Harvard Medical School effective July 1, 2001. In this proposal, the applicant wishes to build on his findings that P-glycoprotein serves critical roles in vitro in T cell activation and APC function. He has found that specific P- glycoprotein blockade inhibits alloantigen- but not mitogen-dependent T cell activation by inhibiting IFN-gamma and IL-12 through a positive feedback loop, thus blocking a critical pathway in the initiation of primary alloimmune responses. These mechanisms may also be operative in vivo and Pglycoprotein may therefore play an important role in clinical allograft rejection. However, the in vivo role of P-glycoprotein in T cell activation and allorecognition has not been explored. In addition, the molecular signals and mechanisms that regulate Pglycoprotein expression by T lymphocytes in the course of alloimmune interactions are currently unknown. The goals of this proposal are to: 1) define the role of P-glycoprotein in the direct and indirect pathways of allorecognition and in allograft rejection in vivo in murine models of allotransplantation; 2) investigate the in vivo function of Pglycoprotein in antigen-specific T cell activation using a murine adoptive transfer system where a small population of peptide-specific CD4+ TCR transgenic T cells can be physically tracked and phenotypically examined; and 3) examine in vitro the role of Pglycoprotein in antigen presenting cell function and in the bi- directional activation of T cells and allogeneic endothelium which is critical for allograft rejection, based on the preliminary identification of a unique capacity of allogeneic endothelium to trigger T cellular P-glycoprotein expression. The applicant's training in molecular biology and cellular immunology has allowed him to discover a novel role of P-glycoprotein in alloimmunity. The applicant realizes that in order to further explore his recent findings he needs additional mentoring. The Mentored Clinical Scientist Development Award will provide the critical opportunity for the applicant to further expand his knowledge in immunology necessary for achieving independence. The Mentor's and the CoMentor's laboratories provide an ideal environment to accomplish the aims of this project because of their strong background in transplantation immunology, their collaborative momentum and their exemplary didactic and ethical curricula. After completing this project the applicant will be familiar with the critical in vitro and in vivo techniques of molecular and cellular immunology in order to examine independently and competitively the role of related or novel molecular targets in transplantation and allograft rejection.

GONDII Principal Investigator & Institution: Joiner, Keith A.; Professor; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 01-AUG-1990; Project End 31-JUL-2007 Summary: (provided by applicant): Toxoplasma gondii is an important cause of focal central nervous system infections in patients with HIV, lethal infections in heart transplant patients, and devastating congenital infections of newborns. The organism is an obligate intracellular protozoan parasite, which is capable of invading and replicating in essentially all nucleated cells, and requires nutrients from the host cell to survive and replicate. The parasite resides in an unusual intracellular vacuole, which is extensively modified by secretion from parasite secretory organelles. The focus of our laboratory is to understand how these parasite-induced modifications of the vacuole contribute to the nutrient acquisition necessary for virulence. We have recently demonstrated that the parasite induces a unique process of microtubule-based invaginations from the host cell cytosol into the vacuolar space, for acquisition of nutrients internalized into the host cell via the host endocytic pathway. In particular, cholesterol internalized into the host cell via the LDL receptor is delivered to the parasite via this pathway. Cholesterol transport and metabolism by the parasite are targets for therapeutic intervention, since the organism cannot synthesize sterols de novo. In contrast, nothing is known about the biosynthetic capacity of the organism for phospholipids, nor about mechanisms for phospholipid acquisition from the host cell. These topics are readily amenable to study. For example, as one of many pieces of intriguing preliminary data, we show that extracellular parasites cannot synthesize phosphatidylcholine, the major T. gondii phospholipid, when provided with the head group precursor choline. Unlike cholesterol, this lipid should not be readily acquired from the host cell endocytic pathway, and must be accessed by another route. To elucidate a coherent scheme for phospholipid homeostasis in T. gondii, we will systematically determine 1.) Which phospholipids are synthesized by the parasite, 2.) which phospholipids are acquired from the host cell, 3.) the molecular mechanisms by which the parasite acquires needed phospholipids from the host cell. The long-term goal is to identify strategies to block T. gondii phospholipid acquisition from the host cell and thus to interfere with parasite growth.

Project Title: POST-TRANSPLANT INFLAMMATORY RESPONSE Principal Investigator & Institution: Fairchild, Robert L.; Staff; Cleveland Clinic Foundation 9500 Euclid Ave Cleveland, Oh 44195 Timing: Fiscal Year 2002; Project Start 01-APR-1997; Project End 31-MAR-2007 Summary: (provided by applicant): Acute rejection of allografts remains a significant problem in clinical transplantation, undermining the function and survival of organs transplanted for the treatment of end-stage organ disease. Acute rejection is mediated by the coordinated infiltration and effector functions of T cells with specificity for alloantigens resulting in the destruction of the graft tissue. The factors directing T cells and other leukocytes into solid organ allografts remain poorly defined. In studies performed during the initial funding period of this grant we demonstrated the temporal induction of chemoattractant cytokines, chemokines, in skin allografts during the progression of acute rejection. Administration of antibodies to one of these chemokines, Mig, inhibited T cell infiltration into skin allografts and promoted long-term graft survival supporting the use of this strategy in transplantation. Our preliminary studies

using a heart allograft model have indicated that an early program of inflammatory events regulates the production of T cell chemoattractants and T cell infiltration into the allografts. Antagonism of specific components of this early inflammation delays subsequent infiltration of alloantigen-pnmed T cells into these grafts and significantly extends allograft survival. In this competitive renewal application we will test the induction and inter-dependent relationships between specific components of the inflammatory response that leads to the production of the T cell chemoattractants such as Mig using a mouse model of vascularized heart allograft rejection. In Specific Aim 1 we will test the induction and role of TNFa and IL-1 on the induction of early chemokines anad later T cell chemoattractants in heart allografts. In Specific Aim 2 we will test the role of neutrophils and neutrophil and macrophage chemoattractants in the production of the T cell chemoattractants. Experiments in Specific Aim 3 will test the synergy between the adhesion molecule ICAM-1 and chemokines in directing leukocyte infiltration into heart allografts and the progression of inflammation during acute allograft rejection. The understanding of the role of each of these early inflammatory events in acute rejection should further elucidate important mechanisms of acute allograft rejection. Furthermore, the results should support the development of novel therapeutic reagents and strategies to inhibit these early inflammatory events and promote the survival of transplanted organs while decreasing the dependence on the generalized and debilitating immunosuppressive regimens currently in use.

Project Title: PRESERVATION AND CARDIAC TRANSPLANT VASCULOPATHY Principal Investigator & Institution: Pinsky, David J.; Professor and Scientific Director; Medicine; Columbia University Health Sciences New York, Ny 10032 Timing: Fiscal Year 2002; Project Start 01-JUL-1999; Project End 31-MAY-2003 Summary: (adapted from the applicant's abstract): Mechanisms responsible for vascular failure of cardiac grafts, especially the development of transplant-associated coronary artery disease (TCAD), remain obscure. In a murine model of heart transplantation, preliminary data show a direct correlation between extent of initial ischemic injury and the degree of neointimal proliferation, more pronounced in allografts yet nevertheless present in isografts. To elucidate alloantigen-independent mechanisms of graft vascular injury caused by preservation, ischemic vessels were shown to exhibit a loss of vasoprotective nitric oxide (NO) and cyclic nucleotides, increased expression of leukocyte adhesion receptors and plasminogen activator inhibitor-1, inhibited expression of plasminogen activator genes, and increased reactive oxygen species. Novel electrochemical sensors show L-arginine or tetrahydrobiopterin deficiency subverts cNOS to make O2-, and that NO nearly vanishes after murine CTX due to rapid quenching by O2-; restoring deficient second messenger pathways (NO,cAMP, cGMP) with substrates, analogs, or type specific phosphodiesterase inhibitors improves acute graft vascular function and causes a striking reduction in TCAD; these benefits were reversed by inhibiting PKA. As adhesion receptor-null grafts (P-selectin, ICAM-1) or those puled with interleukin-1 receptor antagonist (IL-1ra) are protected from early vascular failure following prolonged preservation, the investigators hypothesize that early ischemic injury drives primary vascular failure and accelerates TCAD development, particularly in alloreactive vessels. The aims are (1) to elucidate mechanisms of preservation injury which contribute to primary graft failure or TCAD. Effects of preservation on electrochemical, functional, and histomorphometric endpoints will be studied in control, transgenic, or gene-deficient mice to assess the functional relevance of genes which modulate the cytokine, leukocyte adhesive, fibrinolytic, or

reactive oxidant milieu of the graft vasculature; and (2) to determine if attenuating early graft vascular injury can limit primary graft failure and TCAD development, examining the effects of early modulation of NO or cyclic nucleotide pathways, blockade of endothelial-leukocyte interactions, reduction of graft oxidant stress, or inhibition of intravascular thrombosis. An optimal cardiac preservation strategy will then be devised which protects early graft vascular function and reduces the occurrence or severity of TCAD. These experiments will provide new insights into mechanisms by which early ischemic injury leads to early graft failure and TCAD, and proffer new strategies for prevention.

Pigs are now regarded as the most likely species to serve as donors for clinical xenotransplantation. The first major immunological barrier to overcome to allow successful xenotransplantation is rejection by natural antibodies (NAB) present in humans that are directed toward the carbohydrate epitope Gal(alpha1-3)Gal(beta1-4)GIcNAc-R (alphaGal) on porcine tissues. Like humans, knockout mice (GTo) carrying a null mutation in the gene encoding the glucosyltransferase UDP galactose:beta-D- galactosyl-1,4-N-acetyI-D-glucosaminide alpha(1-3)galactosyltransferase (E.C. 2.4.1.151, hereafter referred to as alphaGT) lack alphaGal epitopes on all tissues and develop in their serum NAB reactive against alphaGal. We have shown previously in GTo mice that genetic engineering of bone marrow (BM) using retroviral transduction to establish molecular chimerism can be used to induce long-term stable tolerance to alphaGal and prevent antibody mediated hyperacute rejection of cardiac transplants. These results demonstrate that B cells producing alphaGal reactive antibodies are functionally eliminated from the immunological repertoire of animals that express the retrovirally transduced alphaGT gene in BM derived cells. The goal of this proposal is to test the hypothesis that establishment of molecular chimerism can be similarly used to induce tolerance to the alphaGal epitope in non-human primates. The specific aims are to: 1) Determine the effect of molecular chimerism on production of alphaGal reactive NAB in primates; and 2) Determine whether the induction of molecular chimerism leads to tolerance to alphaGal in primates and determine the mechanism. These studies should provide practical mechanistic information important for the field of xenotransplantation and to the application of gene therapy to induce B cell tolerance, and may also advance our understanding of self-nonself discrimination in shaping the B cell repertoire. Furthermore, these studies may be generally applicable for re-establishing B cell tolerance in individuals with autoimmunity. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Timing: Fiscal Year 2003; Project Start 15-JUN-2003; Project End 31-MAY-2004 Summary: (provided by the applicant): Transplantation represents the only therapy for end-stage organ failure caused by a variety of incurable diseases. However, rejection by the host represents a major obstacle to long-term survival of transplants. While acute rejection is currently controlled by immunosuppressive drugs, continuous treatment with these non-selective agents impairs the entire immune system thereby increasing the risk for infections and cancer in patients. In addition, many of these drugs exhibit longterm toxic effects. Most importantly, a large proportion of solid organ transplants succumb to chronic rejection, a phenomenon associated with fibrosis, and vasculopathy. At present time, there is no treatment for chronic rejection. These observations underscore the need for novel therapies in transplantation. Eukarion Inc. has developed a class of low molecular weight molecules that are catalytic reactive oxygen species scavengers, acting as mimics for the endogenous antioxidant enzymes, superoxide dismutase and catalase. These compounds have demonstrated efficacy in 3 of the main events associated with tranplant rejection" i) tissue damage due to anoxia, ii) ischemia/reperfusion injury and iii) inflammation. Most importantly, we have shown that one of these compounds can delay the acute rejection of skin grafts in mice. Based on these observations we intend to develop a series a compounds with greater lipophilicity and in vivo half-life to be tested in the prevention of acute and/or chronic rejection of solid organ transplants for further development. To achieve this, we propose the following specific aims: 1) To synthesize and evaluate a series of analogs with greater potency or efficacy, i.e., a series with enhanced lipophilicity and improved in vivo half-life. 2) To test the effect of selected EUK compounds on anti-donor inflammatory immune response and on the rejection of heart allotransplants in mice.

The first year after TX is characterized by rapid bone loss (%5 to 12%) at the spine and hip and a very high fracture incidence (20% to 40%). Most studies show that done density stabilizes or improves during the second, and third post-transplant years. We therefore hypothesized that therapy to prevent bone loss could be limited to the first post-transplant years. We therefor hypothesized that therapy to prevent bone loss could be limited to the first post-transplant year. We have completed recruitment (n=146) to a one-year, doublemasked phase III clinical trial evaluating the safety and efficacy of two drugs in the prevention of bone loss during the first 12 months after cardiac transplantation: calcitirol [1,25 dihydroxvitamin D] and the bisphosphonate, alendrona te (ALN). Enrollment was completed in June of 2001 and 12 months of follow-up for all participants will be completed in June of 2002. In addition, we have prospectively monitored enrolled participants to assess the effect of study drug withdrawal on rates of bone loss, and fracture during the second and third post-transplant years. Approximately 50% of subjects begin to experience bone loss (ranging as high as 8% at the spine and 9% at the hip) after study drugs are withdrawn. This observation raises several important therapeutic questions. Most important is whether one year of therapy will suffice to prevent osteoporosis after cardiac TX. It is also important to determine whether ALN

and calcitirol differ with regard to maintenance of bone density after withdrawal and to elucidate the mechanisms and predictors of bone loss during the second and third posttransplant years. We hypothesize, given the long half-life of bisphosphonates in bone, that subjects who received ALN during the tr ial will be less likely to sustain bone loss after withdrawal of study drugs than those who received calcitirol. Funding for the trial ends in March, 2002. We are now applying for 3 years of support to complete 12 months of observation on those subjects enrolled after March, 2001 and to complete an additional 24 months of follow-up on enrolled participants.

and molecular virology and the mouse animal model and he has recently taken a faculty position at the University of Minnesota, which is renowned for research in the fields of transplantation and pig diseases. The research project will investigate the risk posed by persistent porcine viruses, which may escape detection by standard screening methods to become pathogenic in humans following xenotransplatation. The experiments will utilize porcine encephalomyocarditis virus (EMCV), which has been shown to causespecies infection, to evaluate the risk of human infection after transplantation of pig tissues by examining various pigs tissues/organs using sensitive molecular techniques to determine where the virus persists. Subsequently, the applicants will transplant chronically EMCV-infected porcine tissues into SCID (severe combined immunodeficient) mice reconstituted with human peripheral blood lymphocytes followed by immunosuppressive treatment (hu-PBL-ISCID), in order to determine the risk of such tissues transmitting disease. The hu-PBL-ISCID mice will serve as a model of suppressed immune system in transplant patients. This training program will also require the candidate to observe and assist in monkey-to-monkey (allo-) and pig-tomonkey (xeno-) transplantations in an established transplantation laboratory. The longterm goal is to transplant pig organs/tissues containing persistent porcine virus into primates in order to determine the risk of disease.

Project Title: ROLE OF AUTOIMMUNITY IN TRANSPLANT REJECTION Principal Investigator & Institution: Benichou, Gilles A.; Massachusetts General Hospital 55 Fruit St Boston, Ma 02114 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-MAY-2008 Summary: (provided by applicant): The exact role of graft tissue specific antigens in transplant rejection is unknown. Recently, we have detected CD4+ T cell- and B cellmediated autoimmunity to cardiac myosin (CM) in murine, porcine, and human recipients of heart transplants. CM is known to initiate autoimmune myocarditis, an autoimmune disease causing cardiac tissue damage and heart failure. Most importantly, we have shown that: 1) pre-transplant sensitization of recipients to CM causes accelerated allograft rejection, 2) induced anti-CM responses are sufficient to trigger rejection of syngeneic heart grafts and 3) modulation of anti-CM responses in recipients results in long-term survival of transplanted hearts. Based on these results, we hypothesize that, in heart-transplanted individuals, the CD4 pathway of alloresponse contributes to acute and/or chronic heart graft rejection by triggering autoimmune responses to CM thereby causing cardiac tissue damages in a fashion similar to that observed in autoimmune myocarditis. To test this hypothesis, the specific aims of the present proposal are to: 1) identify CM determinants and characterize T cells mediating CM autoimmunity post-heart transplantation and, 2) investigate the mechanism(s) by which alloresponse causes autoimmunity to CM in heart-transplanted mice and, and 3) to elucidate the mechanisms by which modulation of anti-CM response can impact the rejection of heart allografts. We anticipate that this knowledge will provide new insights into the mechanisms governing the immune rejection of allotransplants and set the path for the development of new diagnostic tools and selective immune therapies to alleviate graft rejection in clinical transplantation. This award will enhance my career development by allowing me to devote my primary research effort to new transgenic and chimeric mice and a tissue-specific peptide approach for modulation in vivo of antigraft immunity. This will directly complement my previous training in heart transplantation and enhance my career interest in learning new ways of preventing anti-

Project Title: ROLE OF NEW T CELL PATHWAYS IN ALLOIMMUNITY Principal Investigator & Institution: Sayegh, Mohammed; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2008 Summary: The main goal of this project is to study the role of novel T cell costimulatory pathways in regulating alloimmune responses in vivo. We have a number of unique tools that will enable us to dissect the functions, mechanisms, and interactions of newly discovered T cell costimulatory pathways in regulating alloimmune responses in vivo. The proposal has two major specific aims. In aim 1, we plan to investigate the functions of novel T-cell costimulatory pathways in regulating alloimmune responses in vivo using models of solid organ and tissue (skin) transplants. Initially, we will focus on studying the functions of the PD1-PDLI/PDL2 pathway in regulating alloimmune responses in vivo. In future years we plan to study the functions of newer pathways as they are initially identified and appropriate reagents and animals are generated by the cores of the overall program project. Our hypothesis is that the PD1-PDLI/PDL2 pathway negatively regulates alloimmune responses in vivo. We will use gene targeting approaches and blocking monoclonal antibodies as tools to investigate the functions of this new pathway in alloimmune responses in vivo. We will define the role of this pathway in regulating CD4+ and CD8+ alloreactive T cells, Thl and Th2 alloimmune responses, and acute and chronic rejection using established skin and vascularized cardiac transplantation models in mice. We will also define the interactions between the PD1 pathway and other CD28 homologues (CD28, CTLA4, ICOS). Our corollary hypothesis is that signaling through PD1 promotes tolerance in alloreactive T cells. We will test novel therapeutic combinations using a PDL1Fc to promote donor specific tolerance. We will use unique in vitro and in vivo assays including specific TCR transgenic animals with defined allospecificity to class I (CD8) or class II MHC (CD4) alloantigens to better understand the mechanisms of targeting the PD1 costimulatory pathway in vivo. In aim 2 we will focus on developing non-toxic strategies to achieve donor bone marrow chimerism across fully allogeneic barriers without chemoradiotherapy conditioning. Our hypothesis is that targeting T cell costimulatory pathways promotes development of mixed allogeneic chimerism without chemoradiotherapy. We will target well defined and new T costimulatory pathways that are known to regulate initial CD4+ and CD8+ T cell expansion and/or subsequent survival. Successful strategies that induce donor T cell chimerism will be tested for specificity of tolerance using donor and third party skin graft rejection as a stringent transplant model. Furthermore, using novel models permitting tracking of host antidonor alloreactive CD4+ and CD8+ TCR transgenic T cells, we will examine the biology of graft resistance and determine how targeting new T cell costimulatory pathways affect alloreactivity in the context of mixed allogeneic chimerism. Overall, the studies in this project will dissect the functions and mechanisms of novel T cell costimulatory pathways in allograft rejection and tolerance. The results should yield useful information for future development of novel therapeutic strategies to induce transplantation tolerance to translate to primates and humans.

We will test the hypothesis that: (i) the speed with which T reg cells expand after Ag activation and (ii) the pool size and potency of counteracting alloaggressive T cells are the variables that determine whether rejection or tolerance will occur. The overall aim of this proposal is to full define the role, phenotype, molecular mechanism of action, limitations of T reg cells in governing the allograft response.

Project Title: ROLE OF THE GRANZYME B PATHWAY IN AGA Principal Investigator & Institution: Rosen, Antony; Professor; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2008 Summary: The long-term objectives of this project are to define the role of the granzyme B pathway in accelerated graft atherosclerosis, and its predominant mechanisms of pathogenesis in this setting. Recent data has underscored the fact that the granzyme B pathway plays a central role in transplant rejection, acting through induction of death and dysfunction of target cells through cleavage of highly specific intracellular and extracellular substrates. In preliminary studies, we have demonstrated that differentiated vascular smooth muscle cells (vSMCs) are preferentially and highly susceptible to granzyme B-induced proteolysis, and have observed that fibrillin-1 (a component of microfibrils in extracellular matrix which is prominent in blood vessels) is efficiently cleaved by granzyme B. We hypothesize that the granzyme B pathway plays a critical role in initiating and driving the specific vascular phenotype in AGA, through induction of ongoing damage of differentiated vSMCs, and cleavage of a critical extracellular matrix signal which leads to dysregulation of smooth muscle cell and endothelial cell function. We will address this hypothesis through the following specific aims: (1) Define the activity, targets and mechanisms of the granzyme B-induced dysfunction in vivo in human cardiac transplantation using unique probes of granzyme B-induced cleavage of intracellular and extracellular substrates; (2) Define the functional consequences of the granzyme B pathway on vessel structure and function, including intact vessels and isolated smooth muscle cells in vitro; (3) Address the role of granzyme B in development of AGA lesions in vivo by examining the effects of deficiency of GrB either in the whole animal or in distinct microenvironments, using granzyme B-deficient mice or mice expressing intracellular or secreted forms of a potent GrB inhibitor in vascular smooth muscle cells.

Heart Transplant
Summary: (adapted from applicants's abstract) Immunosuppressive gene therapy holds promise as an inductive therapy in transplantation. However, many fundamental aspects of this technology must be addressed before it may be applied to clinical transplantation. These include questions regarding the use of viral vs. non-viral vectors, underlying mechanisms of action, effects on systemic immunity, and the duration of transgene expression. The investigators have developed a model of TGFbeta1 gene transfer into mouse vascularized cardiac allografts to address these issues. Donor hearts are perfused with either DNA-liposome complexes or adenoviral vectors which encode the active form of TGFbeta1. Interestingly, CD4+ cells are readily suppressed by this modality, while CD8+ cells are not. This differential sensitivity is most pronounced when adenoviral vectors are used. The overall hypothesis to be tested is that transient depletion of CD8+ cells will enhance the efficacy of immunosuppressive gene therapy. Hence, the Specific Aims will: 1) Define mechanisms by which TGFbeta1 gene transfer mediates immunosuppressive activities. T cell functional assays will identify critical immune functions which are either turned off or turned on by TGFbeta1 gene transfer, and adoptive transfer studies will determine if regulatory cells are induced by TGFbeta1 gene transfer. 2) Elucidate mechanisms by which adenoviral mediated TGFbeta1 gene transfer stimulates CD8+ cells. The investigators will test the hypothesis that adenoviral vectors, but not DNA-liposome complexes, stimulate production of inflammatory cytokines which over-ride TGFbeta1 suppression of CD8+ cells. 3) Determine the impact of TGFbeta1 gene transfer on systemic immune surveillance. They will assess the effects of TGFbeta1 gene transfer on primary and memory responses to Listeria and on antibody responses to influenza immunization. 4) Determine if TGFbeta1 gene expression may be silenced following initial inductive immunosuppression. Tetracycline regulated promoters will be used to limit the duration of TGFbeta1 expression, and gene transfer of decorin, which binds and neutralizes TGFbeta1, will be employed to neutralize the transgene product. This study will provide insight for optimizing immunosuppressive gene therapy in clinical transplantation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

ORGAN
Principal Investigator & Institution: Khanna, Ashwani K.; Medicine; Medical College of Wisconsin Po Box26509 Milwaukee, Wi 532260509 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2004 Summary: (adapted from applicant's abstract): The investigators and others have previously demonstrated that CsA and more recently tacrolimus (Tac) induce transforming growth factor beta (TGF-B). A number of studies have demonstrated that TGF-B is both immunosuppressive and fibrogenic. Recently, they demonstrated that TGF-B mimics and anti-TGF-B abrogates both the anti-proliferative and fibrogenic effects of CsA in a non-transplant short-term in vivo mouse model. Cell-cycle arrest appears to be at least one main feature of the efficacy of immunosuppressive drugs, and TGF-B has been reported to induce the expression of one cell cycle inhibitor, p21. The investigators' that this phenomenon may be TGF-B- independent. If confirmed, these intriguing findings would suggest a potential dichotomy between at least some of the immunosuppressive properties of these agents and their fibrogenic effects, thus providing targets for pharmacologic modification to enhance or diminish specific properties. The current hypothesis based on these newer findings is that the efficacy of CsA and Tac is multifactorial and, in addition to the effects on TGF-B and IL-2, directly induces cell cycle inhibitors such as p21. The investigators also propose that the primary

53
toxic effects of CsA and Tac are via the induction of TGF-B, which then induces fibrogenic genes including collagen and fibronectin. Accordingly, the specific aims of this proposal are 1) To determine whether the efficacy of CsA and Tac are dependent on TGF-B, p21 or both, using the complete MHC mismatch rat heart transplant model, which requires chronic immunosuppression to prevent rejection. The investigators will use antibodies to TGF-B and p21 alone or in combination to determine whether acute rejection is accelerated in CsA and Tac treated animals within the first 30 days posttransplant. 2) To further dissect the interaction between CsA and Tac, TGF-B and p21, using in vitro studies on A-549 cells that are either unmodified or are TGF-B- or p21deficient. The effect of CsA and Tac on the stimulation of promoter activity of p21 gene will be studied using TGF-B inducible and non-inducible promoter constructs made chimeric with luciferase reporter gene. 3) To determine whether the nephrotoxicity of CsA and Tac are secondary to TGF-B. In non-transplanted animals treated with CsA or Tac over 3-6 months, the investigators will use anti-TGF-B antibodies to attempt to abrogate the nephrotoxic effects. Also, to determine the time course of the induction of TGF-B1 and the ECM genes collagen and fibronectin, they will investigate the induction of these genes by CsA and Tac in glomerular mesangial cells and proximal tubular epithelial cells in vitro. These studies will directly determine the role (if any) of the TGFB and/or p21 pathways in the efficacy, and TGF-B in the toxicity, induced by CsA and tacrolimus.

Project Title: THE ROLE OF FRACTALKINE IN ALLOGRAFT REJECTION Principal Investigator & Institution: Robinson, Lisa A.; Pediatrics; Duke University Durham, Nc 27706 Timing: Fiscal Year 2002; Project Start 01-JUN-2001; Project End 31-MAY-2003 Summary: Fractalkine (FKN) is a novel chemokine/mucin hybrid molecule expressed on the surface of activated endothelium which has dual functions as a chemokine and an endothelial adhesion molecule. Our preliminary studies have identified a unique role for FKN in the pathogenesis of transplant rejection. The objective of this proposal is to develop a detailed understanding of the proinflammatory actions of FKN and its receptor CX3CR1 in immune responses such as allograft rejection. We hypothesize that these actions are determined by regulated expression of FYN on endothelial cell surfaces and that one contribution of FKN is to directly promote cellular immune functions. We will test these hypotheses through the following specific aims: Specific Aim #1: To characterize the actions of FKN and CX3CR1 to regulate immune cell functions. In preliminary studies, we have identified potent actions of FKN to promote certain cellular immune functions. We will systematically examine the role of FKN in regulating the activities of two inflammatory cell populations that are known to express CX3CR1: NK cells and macrophages. We will focus on effector functions that are relevant to allograft rejection. Specific Aim #2: To identify the mechanisms that regulate FKN expression on endothelium in an inflammatory response. Our preliminary experiments have demonstrated novel regulation of endothelial expression of FKN by the lipid mediator thromboxane A2. These studies will define the molecular mechanisms of this regulation and will examine the relevance of this pathway in an ongoing inflammatory response. We posit that this may be a critical component of platelet-endothelial interactions during inflammation. Specific Aim #3: To define the role of FKN and CX3CR1 in the pathogenesis of allograft rejection. In these experiments, we will examine the contribution of FKN and CX3CR1 to allograft rejection in a series of experimental models. Using a combination of neutralizing antibodies and genetically altered mice, we

will define the role of the FKN- CX3CR1 pathway in acute and chronic allograft injury. These studies will test whether the in vitro actions of FKN defined in previous aims are relevant to in vivo immune responses. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: THE USE OF PRIMATES FOR HUMAN XENOTRANSPLANTATION Principal Investigator & Institution: Zahorsky-Reeves, Joanne L.; Cardiothoracic Surgery; University of Southern California 2250 Alcazar Street, Csc-219 Los Angeles, Ca 90033 Timing: Fiscal Year 2002; Project Start 15-MAR-2001; Project End 28-FEB-2006 Summary: The long-term objective of this application is the prevention of the humoral rejection of porcine xenografts in patients. The objective of the current proposal is a detailed characterization of the xenoantibody response of an experimental model for human xenotransplantation, the cynomolgus monkey, and validation of this model as the basis for conducting clinically relevant experiments to prevent xenograft rejection in humans. In pursuit of this objective, our specific aims include determining the binding characteristics of IgM and IgG xenoantibodies in the cynomolgus monkey, and the sequences of the VH genes encoding them, both before and after transplantation of a vascularized porcine graft. Once this genetic information has been obtained, it will be used in the development and in vitro testing of an anti-idiotypic antibody against those xenoantibodies with the highest affinity to identified xenoantigens. This research should result in the full characterization of the xenoantibody response of an experimental model for human xenotransplantation and validation of this model as the basis for conducting clinically relevant experiments to prevent xenograft rejection in humans. Dr. Joanne Zahorsky-Reeves will be working under her mentor, Dr. Donald V. Cramer, in a laboratory with extensive background in the xenoantibody response in both rodent and human models. The applicant will become proficient in a variety of molecular biology techniques, including the development and screening of genetic libraries; the creation of single-chain antibodies; the production of anti-idiotypic antibodies using a mouse hybridoma system; and the evaluation of those anti-idiotypic Antibodies to specifically target and eliminate antibody- producing B cells. Mastering of these techniques will allow Dr. Zahorsky-Reeves to become an independent animal-based research not only in the field of xenotransplantation, but, broadly, in a variety of immunological settings.

Project Title: TISSUE ENGINEERING OF A CARDIAC PATCH Principal Investigator & Institution: Terracio, Louis; Associate Dean for Resarch; Basic Science and Craniofacial Biology; New York University 15 Washington Place New York, Ny 10003 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-JUL-2005 Summary: (provided by applicant): Despite a dramatic decline over the past 15 years, cardiovascular disease remains the leading cause of death and disability in the Western world. The adult onset disease processes that compromise cardiac function include, infarction, ischemic heart disease, myocarditis, and a variety of idiopathic cardiomyopathies. The focal loss of muscular tissue, as a result of a congenital defect or a disease process, alters the unique architectural arrangement of the heart and impairs its function. An engineered segment of artificial myocardium (cardiac patch) potentially offers a nearly unlimited source of material for reconstructive surgery. In preliminary experiments from our lab we have successfully constructed small, multilayered cultures

of fetal and neonatal cardiac myocytes that exhibit a tissue-like pattern of organization. These multilayered cultures are composed of myocytes that have an elongated, rod-like cell shape, but require further development before they would be suitable for transplantation. This proposal takes advantage of the Pl's experience in cardiac development, in vitro cultivation of cardiac myocytes on various ECM components, in vitro mechanical stimulation of cells in culture, morphological characterization of tissues, proof of concept studies, and established collaborations with bioengineering colleagues. The Specific Aims of this proposal are: 1) To use specially fabricated collagen substrates and a series of bioreactors to produce histotypic cultures of cardiac cells suitable for transplantation. 2) Characterize and compare the artificial myocardium to the intact heart by morphometric, biochemical and molecular techniques. 3) Transplant the artificial myocardium to in vivo locations that will allow vascularization of the tissue. The transplanted cultures will be compared by morphometric, biochemical, and molecular techniques to the structure and function of the intact heart. Data from these studies will identify the mechanical and chemical parameters necessary to produce the three-dimensional organization of the heart patches. These cultures will provide a potential source of biological material for repairing focal damage to the myocardium. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: TOLERANCE IN PRIMATES--THYMIC IMPLANTATION OF STEM CELL Principal Investigator & Institution: Allen, Margaret D.; The Hope Heart Institute 528 18Th Ave Seattle, Wa 98122 Timing: Fiscal Year 2002; Project Start 15-MAR-1995; Project End 30-SEP-2004 Summary: The aim of this proposal is to test in primates a new method for producing tolerance to solid organ grafts: implantation of purified donor CD34+ marrow cells into the recipient thymus. In pilot studies, the investigators have achieved: 1) hematopoietic microchimerism in 6/6 juvenile baboons with or without current triple drug immunosuppression; 2) specific prolongation of donor versus third party skin graft survival; and 3) absence of graft versus host disease at 16 months. These experiments test the feasibility of extending this approach to cardiac transplantation in a juvenile baboon model as a pre-clinical trial. The following questions are addressed: 1) Does intrathymic implantation of CD34+ marrow cells prolong survival of cardiac allografts? 2) What is the relationship between hematopoietic microchimerism and tolerance to a cardiac allograft? 3) Is intrathymic implantation of stem cells more effective than peripheral infusion? 4) What are the effects of current drug therapy on engraftment and tolerance? 5) What is the optimal timing of stem cell administration relative to cardiac transplantation? 6) What dose of cells is needed? 7) Are DR+ fractions necessary for engraftment? 8) Are measures of cellular immunity altered? Experiments are performed in juvenile baboons, implanting CD34+ cells in the thymus through a small thoracotomy and using a cervical heterotopic cardiac graft which facilitates biopsies. Immunosuppression consists of the tripe drug immunosuppressive regimen in current clinical practice, without myeloablation or host T cell depletion, or no immunosuppression. A dose of only 1x 10/6 cells has resulted in hematopoietic microchimerism in all recipients. Persistence of microchimerism. Histologic quantitation of infiltrating leukocyte subsets and coronary microvascular adhesion molecule expression will be compared to controls. The level of chimerism achieved, its persistence, the phenotype of stem cell progeny, effect on donor-directed CTLp, and the dependence on the thymus will be assessed. Implantation of CD34+ marrow cells in the thymus during a cardiac transplant procedure may provide a simple, safe method of

producing tolerance to the graft and microchimerism. This methodology has obvious immediate clinical applications in solid organ transplantation. Depending on the level of chimerism achieved, the potential for introducing allogenic stem cells into an infant without immunosuppression might also have implications for the treatment of genetic deficiency diseases.

Principal Investigator & Institution: Mocarski, Edward S.; Professor; Microbiology and Immunology; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 10-SEP-2001; Project End 30-JUN-2006 Summary: (provided by applicant): The fundamental objective of this Program in Immunopathogenesis of Chronic Graft Rejection is to address "TA: Viral and Host Mechanisms" by understanding pathogenic processes underlying this common manifestation of chronic rejection in heart transplant recipients. The Program Project focuses on the contribution of human cytomegalovirus (HCMV) in conjunction with immunopathogenic and inflammatory modulation that develops in patients who progress to TA. The study involves a large, organized multi-level evaluation of 160 heart transplant recipients. Peripheral blood and endomyocardial biopsy specimens will be collected eight times over the first year and three times in successive years to follow immune, virologic and inflammatory indicators that will be correlated with TA. The first project in this program will focus on the contribution of the HCMV-specific CD4 and CD8 T cell memory/effector function during the reactivation from latent or the initiation of primary infection and the progression to TA. This project will also investigate the activation state of cells. An inverse correlation is expected between the risk of progression to TA and the frequency of functional HCMV-specific T cells. The second project of this program will focus on levels of HCMV DNA and the induction of viral gene expression in patients at risk of TA. Sensitive solution and in situ DNA amplification and hybridization approaches will be used to follow viral DNA and mRNA levels in the follow-up period. This project will investigate the role of virus encoded or -induced chemokine (UL146/vCXC-l) and chemokine receptor (US28) expression in progression of TA. The proinflammatory capacity of viral strains and the highly variable UL146 chemokine gene, from patients progressing to TA will be investigated. An increase in virological indicators is expected during progression to TA. The third project will determine the impact of the Nitric Oxide Synthase(NOS) pathway by focusing on two major changes that can be measured in patients: (i) increases in vascular superoxide anion (O2-), and (ii) increases in ADMA. This project will investigate how HCMV infection augments these abnormalities via cytokine induced alterations in oxidative stress and ADMA accumulation. An impact of HCMV on endothelial and inflammatory NOS pathways is expected during progression to TA. Importantly, all three projects will work in parallel in peripheral blood cells/plasma/serum as well as directly in endomyocardial biopsies at all sampling times. Such an intense longitudinal study should provide the best possible setting to uncover associations and identify the contribution of HCMV to TA. The mechanisms, prognostic value and points of therapeutic intervention-directed at HCMV, the immune response to HCMV, immune activation and immunopathogenic events and the role of NOS pathways will all potentially emerge as a result of these collaborative efforts.

Project Title: TREATMENT OF EBV ASSOCIATED LYMPHOPROLIFERATIVE DISEASE Principal Investigator & Institution: Moss, Denis J.; Queensland Institute of Medical Research Herston Brisbane Qld, 4006 Timing: Fiscal Year 2002; Project Start 01-AUG-2001; Project End 31-JUL-2003 Summary: The treatment of Epstein-Barr virus (EBV)-associated lymphoproliferative disease in solid organ transplant patients poses a considerable challenge due to the underlying immunosuppression which inhibits the virus-specific cytotoxic T cell (CTL) response in vivo. Preliminary studies developed in our laboratory suggest that it may be possible to overcome this inherent problem using a novel protocol to activate autologous EBV-specific CTL lines from these patients and to show for the first time their potential use for immunotherapy against PTLD in solid organ transplant patients. To establish the clinical use of this protocol, we propose to conduct a phase I/II clinical trial in a cohort of solid organ transplant patients with PTLD. To achieve this, we have drawn together scientific expertise within the EBV Unit at QIMR and major transplant units in Australia. In the first instances, we propose to further refine the in vitro conditions for activating EBV-specific CTL from solid organ transplant patients who are on high levels of immunosuppression. Two absolute requirements have been set: (1) EBV specificity at the CTL peptide epitope level; and (2) complete lack of anti-donor alloreactivity which would threaten the integrity of the transplanted graft. Having defined these conditions, we propose to conduct a phase I/II trial by adoptively transferring autologous EBV-specific CTL into solid organ heart, lung, and heart/lung transplant patients with PTLD. As far as we are aware, this represents the first such trial to be conducted and seeks to (1) determine the safety of adoptively transferring EBVspecific CTL into solid organ transplant patients; (2) determine the longevity of these CTL in vivo using a genetic marker; and (3) determine the extent of clinical regression of PTLD.

FACTOR
IN
Principal Investigator & Institution: Flaxenburg, Jesse A.; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2005 Summary: (provided by the applicant): Transplant patients are currently subjected to long term morbid therapy with immunosuppressive medications in order to prevent rejection of their grafts. For this reason, it is critical to devise therapies that are more specific and have improved side effect profiles. This will require a greater understanding into the mechanisms of allograft rejection. Vascular endothelial growth factor (VEGF) is the most potent angiogenic factor known. An underappreciated biologic function of VEGF is its role in initiating and perpetuating an inflammatory response through the induction of proinflammatory chemokines. Furthermore, this function of VEGF has major implications for alloimmune recognition. This proposal seeks to elucidate the mechanisms by VEGF can exert an inflammatory response in the setting of alloimmune stimulation. The understanding gained through these experiments is likely to uncover new, more specific targets for the treatment of allograft rejection.

DYSFUNCTION
AFTER
SUBARACHNOID
Principal Investigator & Institution: Zaroff, Jonathan G.; Medicine; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 01-MAY-2000; Project End 31-MAR-2005 Summary: The overall objective of this application is to support the principal investigator's development in a career focused on patient-oriented research. To accomplish this objective, the proposed program has both training and scientific components. The training component will include specific course work and instruction in biostatistics, clinical epidemiology, research methodology, and trial design. The scientific component of the proposed award will be in the field of neurocardiology, with a focus on cardiac dysfunction after subarachnoid hemorrhage (SAH). Many cardiac abnormalities have been reported after SAH. including electrocardiographic changes, arrhythmia, and left ventricular systolic dysfunction. Though many aspects of this syndrome remain unexplained, the most important issues are its undefined pathophysiology, reversibility, and therapy. The scientific program will test the following hypotheses: 2. Left (LV) and right (RV) ventricular systolic dysfunction occurring after SAH are reversible and independent of changes in myocardial perfusion and afterload. 3. Cause of donor brain death (SAH vs. others) and the presence of donor LV dysfunction are predictive of early recipient mortality after cardiac transplantation. A prospective cohort design will be used to determine the incidence and reversibility of RV and LV dysfunction after SAH, using serial echocardiographic measurements. In a substudy of patients with LV ejection fraction <40%, radionuclide imaging with technetium sestabmibi (MIBI) and meta[123]iodobenzylguanidine (MIBG) will be performed in order to determine the incidence of perfusion versus innervation abnormalities and their correlation with regional wall motion abnormalities of the left ventricle. In order to determine whether the observed contractile abnormalities are independent of changes in afterload, the LV end-systolic wall stress / end-systolic volume relationship will be determined in each substudy subject. A secondary analysis of the United Network for Organ Sharing (UNOS) and California Transplant Donor Network databases will be performed in order to determine the effects of donor cause of death and LV dysfunction on early recipient mortality rates.

Project Title: VIRAL CHEMOKINE RECEPTORS: TRANSPLANT VASCULAR SCLEROSIS Principal Investigator & Institution: Orloff, Susan L.; Surgery; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2002; Project Start 01-FEB-2001; Project End 31-JAN-2004 Summary: The long term goal of this project is to identify mechanisms involved with human cytomegalovirus (HCMV) acceleration of transplant vascular sclerosis. The primary cause of graft loss of all vascularized organ transplants is due to a vascular lesion associated with chronic rejection. This form of vasculopathy referred to as TVS is characterized by concentric neointimal smooth muscle cell proliferation that results in vessel occlusion and ultimately graft failure. To date the only therapy available to treat severe TVS is retransplantation. Clinical studies in transplant recipients have demonstrated a direct link between HCMV and the acceleration of TVS. Based on these findings, we have developed a rat model of heart and small bowel transplantation in which CMV infection accelerates the time and severity of TVS. While the exact
Studies

mechanism through which CMV mediates this process is unknown, recent work from our group suggests that CMV may contribute to TVS through induction of smooth muscle cell (SMC) migration towards sites of chemokine production through expression of a virally encoded chemokine receptor (US28). We have also observed that Rat and Murine CMV also induce SMC migration through their respective viral chemokine receptors R33 and M33, which are functional homologues of HCMV US28. We hypothesize that the mechanism of CMV-accelerated TVS involves the expression of virally encoded chemokine receptors leading to intimal SMC migration, which results in the characteristic vascular lesions of TVS. Therefore, we will utilize our in vitro and in vivo models to extend our observations and determine the role of virally encoded chemokine receptors in the development of TVS in three specific aims. First, using a rat cardiac transplant model of chronic rejection, we will determine the effects of virus on the kinetics of disease progression of TVS and the extent of viral expression in tissues as well as the cell types involved in the process. We will also determine the host factors such as chemokines and cytokines, and the contribution of R33 involved at various stages of the development of RCMV-induced TVS. Secondly, we will characterize the R33 domains involved in signaling which induce SMC migration and the ligands, which serve as agonists or antagonists to induced cellular movement. In the last specific, we will generate recombinant RCMV which contain mutations in domains involved in signaling to understand their contribution to TVS in the rat cardiac transplant model. Lastly, antagonists of R33 induced SMC migration in vitro will be tested for their ability to block TVS in the in vivo rat model. These studies will provide a valuable animal model to understand the role of CMV in the acceleration of TVS. In addition completion of these studies will form the basis for novel and rational design of therapeutic strategies to enhance long-term graft survival in HCMV infected transplant recipients.

Project Title: XENOGENEIC STRUCTURE/FUNCTION
NATURAL
ANTIBODY
TARGETS-
Principal Investigator & Institution: Platt, Jeffrey L.; Director; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002; Project Start 01-SEP-1993; Project End 31-AUG-2006 Summary: (provided by applicant): The major problem in the field of transplantation is the lack of human organs and tissues for those who need them. This problem is so severe that by some estimates only 5-15 percent of the organ transplants needed is carried out. One approach to overcoming this problem is to use animal organs in lieu of human organs for transplantation, that is xenotransplantation. While xenotransplantation could in principle solve the problem of the shortage of organs, it is not presently feasible because the immune system of the recipient reacts severely with the graft. The first manifestation of this reaction is hyperacute rejection. Triggered by the binding of xenoreactive antibodies and the activation of complement, hyperacute rejection can now be overcome by various means including the use of pigs expressing human complement regulatory proteins as the source of xenografts. When hyperacute rejection is averted, a xenograft is subject to acute vascular rejection. Acute vascular rejection destroys organ xenografts over a period of days to weeks. It appears to be caused by antibodies in the recipient, which bind to blood vessels in the graft causing activation of endothelial cells and tissue injury that ensues. Fortunately, acute vascular rejection is not an invariable outcome of organ xenografts. Under some conditions, such as when xenoreactive antibodies are temporarily depleted, a graft may seemingly acquire resistance to injury by anti-donor antibodies, a condition referred to as

accommodation. This application proposes studies that will elucidate the nature of the xenoreactive antibodies that cause acute vascular rejection of cardiac xenografts and determine how antibodies or other factors reacting with a graft may induce accommodation. Studies will be conducted in a model system in which porcine hearts are transplanted heterotopically into baboons. The antibodies produced by the baboons in response to the porcine organs will be studied at the time that acute vascular rejection or accommodation occurs. The specificity of those antibodies, number of antigens and frequency in pigs will be determined and the mechanisms by which those antibodies or other factors induce changes in endothelial cells will be ascertained. These experiments will provide information critical to the devising of new strategies for preventing acute vascular rejection or promoting the occurrence of accommodation of cardiac xenografts.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with heart transplant, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “heart transplant” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for heart transplant (hyperlinks lead to article summaries): •

CHAPTER 2. NUTRITION AND HEART TRANSPLANT Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and heart transplant.
Finding Nutrition Studies on Heart Transplant The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “heart transplant” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

Heart Transplant
Sponsor(s): Warren G Magnuson Clinical Center (CC) Purpose - Excerpt: This study will investigate the causes of acute and chronic rejection of transplanted hearts. To find better ways to detect, treat and possibly prevent heart transplant rejection, more information about the cause is needed. Acute and chronic heart transplant rejection may be caused by certain substances the body produces in response to the new heart. This study will try to find a blood or urine test that detects genes and proteins that can serve as markers of rejection. Such a test may lead to earlier detection and improved treatment. Patients between 18 and 65 years of age who are on a wait list for heart transplant at a UNOS-approved heart transplant center, whose institutional review board has approved this protocol, may be eligible for this study. Healthy volunteers will also be included in the study to establish a database of normal values for comparison with patients undergoing heart transplant. In addition, patients who have had a heart transplant within the past 1 to 5 years will be enrolled in a pilot study. Normal volunteers will be screened for participation with an electrocardiogram (EKG) and echocardiogram, non-invasive tests to evaluate heart function. Participants will undergo the following procedures: - Review of medical records - Patients who have had a heart transplant and those on a wait list to receive a heart will have their medical records reviewed to collect information on their condition. - Blood samples - 60 cc (about 3 tablespoons) of blood will be collected from all participants by needle stick in a vein. The sample will be analyzed for genes and proteins that might predict heart rejection. In addition, many genes in blood cells and cells lining blood vessels that are unrelated to heart transplant rejection and whose functions or significance are unknown will also be examined for ideas for future research. Patients enrolled while on a wait list will, after transplantation, have an additional 44 cc (about 2 tablespoons) of blood collected at each heart biopsy and rejection episode during the first year of transplant, and 60 cc collected with each yearly biopsy for the next 9 years. - Urine samples - Between 100 and 300 cc (3 to 10 ounces) of urine may be collected from all participants to confirm blood test results Study Type: Observational Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00042614 •
Efficacy study of Zenapax in combination with CellCept, Cyclosporine and Corticosteroids in heart transplant Condition(s): Transplants Study Status: This study is no longer recruiting patients.

Osteoporosis Prevention After Heart Transplant Condition(s): Osteoporosis; Cardiac transplantation
Clinical Trials 125
Study Status: This study is completed. Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS); Merck Research Laboratories Purpose - Excerpt: During the first year after a heart transplant, people often rapidly lose bone from their spine and hips. About 35 percent of people who receive heart transplants will suffer broken bones during the first year after transplantation. This study will compare the safety and effectiveness of the drug alendronate (Fosamax) and the active form of vitamin D (calcitriol) in preventing bone loss at the spine and hip after a heart transplant. In this study, people who have had a successful heart transplant will receive either active alendronate and a "dummy pill" instead of calcitriol, or active calcitriol and a dummy pill instead of alendronate for the first year after their transplant, starting within 1 month after transplant surgery. We will measure bone density in the hip and spine at the start of the study and after 6 and 12 months, and will also check for broken bones in the spine. This research should lead to ways of preventing this crippling form of osteoporosis. Phase(s): Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00000412
Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “heart transplant” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database.

CHAPTER 5. PATENTS ON HEART TRANSPLANT Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “heart transplant” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on heart transplant, we have not necessarily excluded nonmedical patents in this bibliography.
Patents on Heart Transplant By performing a patent search focusing on heart transplant, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an 9Adapted

Adaptive device for supporting cardiac function during diastolic dysfunction and method therefor Inventor(s): Chekanov; Valeri S. (Franklin, WI) Assignee(s): Heart Care Associates, Llc (milwaukee, Wi) Patent Number: 6,540,666 Date filed: January 8, 2002 Abstract: An adaptive heart binding device and method for the treatment of heart failure. The device has a non-distendible jacket to prevent the heart from expanding beyond a preselect volume. A first chamber corresponding the right ventricle and a second chamber corresponding to the left ventricle are located between the heart and the jacket. The first and second chamber can be inflated to exert additional pressure on the heart over time without additional surgery. The gradual pressure increase hemodynamically remodels the heart so that is performs more like a non-diseased heart. The binding device can be used as a bridge to or in place of heart transplant. Excerpt(s): The present invention pertains to a method and apparatus for treating congestive heart disease and related valvular dysfunction. More particularly, the present invention is directed to an adaptive cardiac constraint having an outer non-extentible device and a pair of inner inflatable members for preventing over-extension of the heart during diastole. Congestive heart disease is a progressive and debilitating illness. The disease is characterized by a progressive enlargement of the heart. As the heart enlarges, the heart is performing an increasing amount of work in order to pump blood each heart beat. In time, the heart becomes so enlarged the heart cannot adequately supply blood. An afflicted patient is fatigued, unable to perform even simple exerting tasks and experiences pain and discomfort. Further, as the heart enlarges, the internal heart valves may not adequately close. This impairs the function of the valves and further reduces the heart's ability to supply blood. Causes of congestive heart failure (CHF) are not fully known. In certain instances, CHF may result from viral infections. In such cases, the heart may enlarge to such an extent that the adverse consequences of heart enlargement continue after the viral infection has passed and the disease continues its progressively debilitating course.

transient infections to aid in preventing, ameliorating, and/or ablating infectious viral heart disease and reducing, or ablating entirely, heart transplant rejection. Additionally, other organs or tissues may be targeted with specific picornaviruses. In particular, an attenuated CVB3 viral vector able to express a cytokine is provided. This cytokineexpressing viral vector is able to deliver the cytokine to a target tissue and reduce disease symptoms. Excerpt(s): The present invention relates generally to the fields of molecular biology and virology. More specifically, the present invention relates to a biologically engineered, attenuated Coxsackievirus and its use as a delivery vehicle for nucleic acids encoding antigenic or biologically active proteins. The coxsackieviruses, members of the family Picornaviridae, are divided into two groups, based essentially on their pathogenicity and replication in newborn mice. The Group B coxsackieviruses (CVB) are composed of six serotypes (1-6). Similar to other members of the Picornaviridae, the CVB genome is a single-stranded, messenger sense, polyadenylated RNA molecule (for review see Romero, J. R. et al., Current Topics in Microbiology and Immunology 223: 97-152, 1997). Genome analysis of the CVB shows that they are organized into a 5' nontranslating region, a protein coding region containing a single open reading frame, a 3' nontranslated region and a terminal poly-A tail, similar to other Picornaviruses. The CVB protein coding region can be further divided into three regions, P1, P2 and P3. P1 encodes the four capsid proteins VP4 (1A), VP2 (1B), VP3 (1C) and VP 1 (1D); P2 and P3 encode the non-structural proteins required for the CVB lifecycle: 2A (protease), 2B, 2C, 3A 3B (Vpg), 3C (protease) and 3D (polymerase) (See Romero et al., 1997, supra). The genomes of CVB that have been fully sequenced are very similar to one another in length, ranging from 7389 nucleotides (CVB1) to 7402 nucleotides (CVB5) (Romero et al., 1997 supra). Variations in length are due to differences within the coding region of VP1 and VP2 (capsid proteins) and in the 5' and 3' non-translated regions. The 5' nontranslated regions also show remarkable similarity in length. For a detailed review of the similarities among the CVB genomes, refer to Romero et al, supra, 1997.

Method and apparatus for heart transplant monitoring and analog telemetry calibration Inventor(s): Mulier; Peter M. J. (St. Paul, MN), Thompson; David L. (Fridley, MN), Wahlstrand; John D. (Shoreview, MN) Assignee(s): Medtronic, Inc. (minneapolis, Mn) Patent Number: 5,402,794 Date filed: July 1, 1992 Abstract: A cardiac pacemaker with an analog telemetry system. A calibration circuit within the pacemaker is adapted to provide a reference signal of known character to the pacemaker's telemetry system. The reference signal is transmitted across the telemetry link as if it were an actual cardiac signal, and received by an external programmer. Since the reference signal has known, predetermined qualities, the programmer can automatically calibrate and scale the telemetry signal from the pacemaker, thereby increasing the accuracy of the telemetry channel. The increased accuracy is particular useful in assessing rejection of a transplanted heart, which is known to be associated with a 15% decline in the peak R-wave amplitude of the cardiac signal.

Heart Transplant
Excerpt(s): This invention relates to the field of cardiac pacemakers, and more particularly to a pacemaker having an automatic calibration signal for an analog telemetry channel. As of Jan. 1, 1991, over 16,000 heart transplants have taken place worldwide, more than 87% of these since 1984 (according to Kreitt et al., "The Registry of the International Society for Heart and Lung Transplantation: Eight Annual Report", The Journal of Heart and Lung Transplantation, Number 4, Jul.-Aug. 1991, pp. 491-498). Rejection of the transplanted heart within two years is the cause of death in 40% or more of all cases. Currently, the preferred method for monitoring rejection is by serial transvenous endomyocardial biopsy. Such a procedure is invasive and relatively traumatic, and must usually be performed at specialized facilities. Typically, two such tests are performed during the first six post-implant months; thereafter, the tests are given less frequently, but throughout the patient's lifetime. Up to a day may be required to obtain results from such a test. One known shortcoming of the serial transvenous endomyocardial biopsy in evaluating heart rejection is that existing scar tissue in the heart, which can occur for various reasons other than heart rejection, can be erroneously interpreted as indicating rejection. It has also been found, however, that certain features of the electrical cardiac signal in transplant patients may also be utilized as an indicator of heart rejection. See, e.g., Warnecke et al., "Noninvasive Monitoring of Cardiac Allograft Rejection by Intramyocardial Electrogram Recordings", Circulation 74 (suppl. III), III-72-III-76, 1986. In particular, it has been found that the onset of heart rejection is accompanied by a reduction of up to 15% in the magnitude of intracardiac R-wave and T-wave peaks. See, e.g., Rosenbloom et al., "Noninvasive Detection of Cardiac Allograft Rejection by Analysis of the Unipolar Peak-to-Peak Amplitude of Intramyocardial Electrograms", Ann. Thorac. Surg., 1989; 47:407-411; see also, e.g., Grace et al., "Diagnosis of Early Cardiac Transplant Rejection by Fall in Evoked T Wave Amplitude Measured Using an Externalized QT Driven Rate Responsive Pacemaker", PACE, vol. 14, Jun. 1991. The ability to monitor and detect this phenomenon would therefore facilitate the early detection and treatment of rejection. To this end, an implantable pacemaker with an accurate analog telemetry channel for transmitting intracardiac signals would greatly enhance the ability of a monitoring physician to assess the cardiac condition.

Method of inotropic treatment of heart disease using hypothermia Inventor(s): Dae; Michael W. (Belmont, CA), Stull; Paul M. (San Mateo, CA) Assignee(s): Radiant Medical, Inc. (redwood City, Ca) Patent Number: 6,607,517 Date filed: August 24, 2001 Abstract: A method for treating cardiac failure such as congestive heart failure by application of hypothermia. Hypothermia may be applied by endovascular cooling using a heat exchange catheter circulating heat exchange fluid between an external heat exchanger controlled using temperature feedback from a temperature probe on or in the patient to cool the heart to a sufficiently low temperature for a sufficient length of time to increase cardiac output and improve the vascular condition of the patient. The patient may be maintained in the hypothermic condition for a period of time and is then rewarmed slowly and controllably. The endovascular temperature management may be controlled automatically in response to a temperature probe on the patient, and shivering while the patient is cool may be combated using surface warming and antishivering drugs. The method is applicable to treat congestive heart failure and may be used repeatedly on the same patient to restore that patient to adequate heart function when the vascular condition of that patient has become unacceptable. The method may be used to maintain a patient until a heart transplant becomes available. The method may be used to stabilize a patient's condition to allow needed surgery or intervention. The method may be used in conjunction with other treatments including drugs, balloon pumps, pacing devices and ventricular assist devices. Excerpt(s): This invention relates generally to methods for medical treatment and more particularly to the application of hypothermia by various means including by endovascular heat exchange to treat chronic heart disease. These methods find particular usefulness in treating congestive heart failure. The condition of heart failure is complex and may be diagnosed by any one or a number of different criteria: the cardiac output may be low, generally consideredbelow 2.5 liters per minute; the stroke volume of the heart may be low, for example below 25 cc; the ejection fraction of the sick heart may be below 40%; there may be echocardiographic findings of enlarged or improperly pumping hear; physical examinations including x-rays and stress testing may indicate cardiac failure; there may be cardiomegally; there may be increased left ventricular wall thickness and chamber dilation indicative of cardiac failure; there may be pulmonary edema, which with other sympotoms and findings may indicate cardiac failure; there may be angiographic findings indicative of heart failure; and a diagnostic test of blood components, such as electrolytes or proteins may indicate heart failure. This lis is not

exhaustive of the symptoms and findings that may help diagnose heart failure, but is offered to show the extent to which heart failure impacts the entire patient and may radically deteriorate the patient's life quality. One common condition is congestive heart failure (CHF). CHF is one of the most serious health problems in the world. An estimated 4.8 million Americans alone have CHF. It is often the end stage of serious heart disease; half of those diagnosed with CHF will be dead within 5 years. An estimated 400,000 new case are diagnosed each year. It is the most common diagnosis in hospital patients age 65 years and older, with the disease affecting 10% of all those over the age of 70. The financial cost of treatment of CHF patients is over $17 billion a year. The human cost is beyond measure. Web site: http://www.delphion.com/details?pn=US06607517__ •
Noninvasive detection of rejection in heart transplant patients Inventor(s): Bianco; Richard W. (Minneapolis, MN), Bolman, III; R. M. (Minneapolis, MN), Slovut; David P. (Golden Valley, MN), Wenstrom; John C. (Salida, CO) Assignee(s): Regents of the Univeristy of Minnesota (minneapolis, Mn) Patent Number: 5,285,793 Date filed: May 21, 1992 Abstract: A method and apparatus for diagnosing heart rejection is disclosed. Heart rejection is diagnosed based on the pattern of interbeat intervals. The interbeat intervals of the heart are measured shortly after transplant to establish a baseline pattern. The patterns of interbeat intervals from subsequent measurements are compared to the baseline to detect changes from the baseline indicating rejection. The apparatus of the invention measures the interbeat intervals using a Schmidt trigger that detects the upstroke of the QRS and produces a corresponding pulse. The intervals between pulses are timed to produce a series of interbeat interval measurements that are stored and analyzed. Software provides for automated pattern analysis. Excerpt(s): The present invention pertains generally to the field of transplant medicine, and more particularly to a device and method for the non-invasive detection of graft rejection in heart transplant recipients. Tissue rejection is the principal cause of heart transplant failures, occurring when a recipient's immune system attacks the transplanted heart. Suppressing this immune system response is critical to the success of heart transplants. Pharmaceutical agents such as Cyclosporine A (CSA), steroids and Azathioprine are used to control and suppress a recipient's immune system response to grafted tissue. However, suppressing a recipient's immune system renders him more vulnerable to infection. Adjusting immune system suppression to the minimum required is thus a major objective. To do this, the transplanted heart tissue must be monitored continuously and carefully for signs of rejection. Recognizing the onset and severity of rejection is a major problem. Tissue rejection in heart transplant recipients is generally silent until the heart is damaged irreversibly. It is crucial to decide whether or not a patient is rejecting his or her transplanted heart, so that potentially life saving therapy can be started immediately. Thus, early and reliable detection of graft rejection is vital to the success of heart transplants. Web site: http://www.delphion.com/details?pn=US05285793__

Noninvasive diagnosis for allograft rejection Inventor(s): Ansari; Aftab A. (Stone Mountain, GA), Sell; Kenneth W. (Atlanta, GA), Villinger; Francois (Decatur, GA) Assignee(s): Emory University (atlanta, Ga) Patent Number: 5,635,365 Date filed: August 7, 1995 Abstract: The present invention provides a noninvasive method for diagnosing and/or predicting a rejection episode in a transplant patient, for example, in a heart transplant patient, by determining a rise in the frequency of thioguanine-resistant mutant peripheral blood mononuclear cells. Those resistant mutant cells have a deficiency in the purine salvage enzyme hypoxanthine guanine phosphoribosyltransferase. The relative frequency of the mutant cells in the population from a sample can be determined by direct plating in the presence of a selection medium and by determining of the mutation by polymerase chain reaction technology. Excerpt(s): The field of this invention is the area of allograft rejection and the diagnosis and/or prediction of allograft rejection. Specifically, the present invention provides a method for the diagnosis and/or prediction of immune rejection of transplanted organs or tissue, for example, a cardiac transplant; the rejection episode is diagnosed or predicted via determination of an increase in the frequency of peripheral blood mononuclear cells lacking hypoxanthine-guanine phosphoribosyltransferase activity. Nearly 2000 heart transplants are performed in the United States each year, and many other organs, such as lung, kidney, liver and pancreas, are transplanted into patients as well. There is a relatively stable population of about 16,000 to 20,000 heart transplant patients. Unfortunately, the average heart transplant patient survives only 8 to 10 years after receiving a transplant. New recipients, as well as the existing cohort of transplant recipients, need to be monitored for evidence of allograft rejection so that treatment can be administered as soon as possible. If transplant rejection is diagnosed relatively late, there is often significant tissue damage in the transplanted organ and hospitalization is almost inevitable. If the damage to the organ is extensive, a retransplant may also be required. The current method for the monitoring and diagnosis of rejection after human cardiac transplant is invasive, and it entails the use of the transvenous myocardial bioptome to procure cardiac biopsy samples, which are then examined for histological evidence of rejection. A graded score of 0 to 4 is used; a score of 0 is assigned where there is no evidence of rejection and 4 is the maximum score of tissue damage and rejection. This pathology-graded score, together with clinical criteria, are used to institute immunosuppressive therapies for heart transplant patients with a diagnosis of rejection. By contrast, liver, kidney and lung transplants can be monitored by noninvasive enzymatic assays of urine and/or blood. However, in those cases, damage to the transplanted organ has occurred by the time diminished function is reflected in the tests, and the present invention provides an earlier method for diagnosis and/or prediction of rejection episodes.

System and method for monitoring heart transplant rejection Inventor(s): Gebhardt; Ursala (Huissen, NL) Assignee(s): Vitatron Medical, B.v. (dieren, Nl) Patent Number: 5,197,480 Date filed: June 8, 1990 Abstract: A pacemaker system and method for predicting cardiac allograft rejection noninvasively through the analysis of the T-wave amplitudes of evoked heartbeats. A pacemaker suitable for detecting the T-wave portions of heartbeat signals, such as the Rhythmyx pacemaker, is utilized for providing T-wave information, preferably the amplitude of the T-wave, which information is analyzed for determining a trend indicative of rejection. A decrease, or diminution of evoked T-wave amplitude indicates rejection, and can be used for appropriate follow-up treatment. Excerpt(s): This invention relates to medical systems and methods for noninvasively monitoring a transplanted heart to diagnose cardiac allograft rejection. It is well known that following human heart transplantation there is danger of rejection of the new heart by the host patient. Such rejection, referred to as cardiac allograft rejection, has been widely studied and discussed in the medical literature. While techniques dealing with, i.e. treating such rejection, have advanced greatly, there still remains a need for accurate, noninvasive, safe and relatively simple diagnosis of such rejection. One technique for determining the condition of the transplanted heart is to perform a biopsy. However, such an invasive technique is clearly not desirable, and there is a substantial need for an accurate and reliable noninvasive means of diagnosis.

Patent Applications on Heart Transplant As of December 2000, U.S. patent applications are open to public viewing.10 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to heart transplant: •
Bag for at least partially enveloping a heart Inventor(s): Haindl, Hans; (Wennigsen, DE) Correspondence: Attention OF Melissa Jean Pytel; Merchant & Gould P.C.; P.O. Box 2903; Minneapolis; MN; 55402-0903; US Patent Application Number: 20020133055 Date filed: May 7, 2002 Abstract: A pouch to at least partly enclose a heart (1), the wall of the pouch (2) being elastic. The purpose of the pouch is to enclose at least part of a heart (1) and to oppose excessive dilation of the heart (1) that might be due to infectious disease of the heart muscle, for instance a viral infection or an autoimmune process. In many cases the use of such a pouch (2) may circumvent the need for a heart transplant.

Excerpt(s): This application is a continuation of application no. PCT/EP98/03619, filed Jun. 16, 1998, which application claims the priority of German application no. 197 26 389.5, filed Jun. 21, 1997, and each of which is incorporated herein by reference. The invention relates to a bag, hereafter called pouch, with which to at least partly enclose a heart. Infectious disease of the heart muscle both by viral infection and by autoimmune processes may lead to enlarged heart volume. If such an enlargement exceeds a critical value, the result will be progressive heart dilation which can be explained by Laplace's law. As the volume subtended by the left heart chamber increases, the stresses in the walls of this cavity will increase. Consequently the muscle fibrils are overloaded and their ideal range of elongation is exceeded. When this excessive elongation takes place, there is, as a rule, a residual volume in the heart. Then the muscle fibrils must operate against a primarily high wall strain, and are further extended thereby. A vicious cycle arises, leading to increasing distension of the heart and consequent heart insufficiency. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Chest cavity classifier apparatus and method for an artificial heart transplant Inventor(s): McNair, Douglas S.; (Gloucester, MA), Mitsa, Theophano; (Beverly, MA) Correspondence: Nutter Mcclennen & Fish Llp; World Trade Center West; 155 Seaport Boulevard; Boston; MA; 02210-2604; US Patent Application Number: 20020188228 Date filed: April 27, 2001 Abstract: An automated classifier receives input data indicative of a prospective surgical patient's mediastinal volume, body surface area and gender, and provides a classifier output signal indicative of quality of fit of a totally implantable artificial heart in the chest cavity of the patient. The present invention assists the surgical team in making their preoperative decision regarding whether or not the totally implantable artificial heart will fit in the chest cavity of the candidate patient. The classifier may also receive as input parameters: the distance between the patient's spine at the sternum at the level of the pulmonary bifurcation; the distance between the spine and the sternum in a caudal heart slice; the maximum left to right distance dimension of the heart; the distance from the rightmost end of the heart to the left chest wall; and the maximum left to right dimension of the chest cavity. Each of the input signals to the classifier is multiplied by an associated regression coefficient, and the resultant products are summed to provide a dependent variable whose value is indicative of quality of fit. To ensure that the classifier provides an accurate measure of quality of fit, the classifier coefficients are developed using a training process, and preferably verified in a testing process. Excerpt(s): The present invention relates generally to cardiac assist devices and, in particular to an automated classifier for assessing preoperatively whether a cardiac assist device will fit within a patient's chest cavity. A totally implantable artificial heart offers the potential for an excellent quality of life for the recipient. Recent progress in modern technology, improvements in surgical techniques and increased understanding of circulatory physiology of cardiac assist device recipients indicate that a permanent mechanical replacement heart is now becoming a viable therapy for the treatment of patients having end-stage heart failure. Realization of this potential requires minimization of the size and weight of the implantable elements including the blood pump assembly. Current design activities have focused on the most effective, anatomically compatible configuration of the blood pump, including the inflow and
136
Heart Transplant
outflow ports. However, because the size, shape and topography of the anatomical structures of the chest cavity vary among patients, a particular blood pump will not fit into the chest cavity of all candidate patients. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

excipient, a therapeutically effective amount of a non-peptide CCR1 receptor antagonist and a sub-nephrotoxic amount of cyclosporin A. Excerpt(s): This is a non-provisional application claiming priority under 35 U.S.C.sctn. 119 provisional application Nos. 601222,053, filed Jul. 31, 2000, and 60/231,282, filed Sep. 8, 2000. The present invention relates to pharmaceutical compositions useful in the treatment of heart transplant rejection in mammals which comprise a pharmaceutically acceptable excipient, a therapeutically effective amount of a non-peptide CCR1 receptor antagonist and a sub-nephrotoxic amount of cyclosporin A. The present invention also relates to a method of using such pharmaceutical compositions in treating heart transplant rejection in mammals. An important component of the inflammatory process involves the migration and activation of select populations of leukocytes from the circulation and their accumulation in the affected tissue. While the idea of leukocyte trafficking is not new, it has enjoyed a renaissance recently following the discovery and characterization of the selectin and integrin families of adhesion molecules and the large family of selective chemotatic cytokines known as chemokines. Chemokine receptors are expressed on leukocytes and process the signals following the binding of the chemokine whereby such signals are eventually transduced into migration or activation of the leukocytes towards the source of the chemokine. Therefore, by regulating the migration and activation of leukocytes from the peripheral blood to extravascular sites in organs, skin, articulations or connective, tissue, chemokines play a critical role in the maintenance of host defense as well as in the development of the immune response.

Use of an angiotensin II receptor antagonist for the preparation of drugs to increase the survival rate of renal transplant patients Inventor(s): Remuzzi, Giuseppe; (Bergamo, IT) Correspondence: Browdy And Neimark, P.L.L.C.; Sutie 300; 624 Ninth Street, N.W.; Washington; DC; 20001-5303; US Patent Application Number: 20020115702 Date filed: February 19, 2002 Abstract: The present invention relates to the use, for the preparation of drugs to increase the survival rate of transplant patients, including renal and heart transplant patients, of a therapeutically effective amount of an angiotension II receptor antagonist compound, such as the class of substituted imidazoles represented by formula (I) and in particular by losartan potassium, 2-butyl-4-chloro-[(2'-tetrazol-5-yl)biphenyl-4-il]methyl]-5-(hydroxymethyl)imidazole potassium salt. Excerpt(s): This invention relates to the use of an angiotensin II receptor antagonist, such as substituted imidazole compounds, for the treatment of Post-transplant hypertension. The invention also relates to use of an angiotensin II receptor antagonist, such as substituted imidazole compounds, for the preparation of drugs to increase the survival rate of transplant patients, including renal transplant patients. The invention also relates to a method of using an angiotensin II receptor antagonist, such as substituted for increasing the survival rate of transplant patients, including renal transplant patients. Substituted imidazoles of formula I are known to inhibit the action of the octapeptide hormone angiotensin II (AII) and are useful therefore in alleviating angiotensin induced hypertension. The enzyme renin acts on a blood plasma.alpha.2-globulin, angiotensinogen, to produce angiotensin I, which is then converted by angiotensin

Heart Transplant
converting-enzyme to AII. The latter substance is a powerful vasopressor agent which has been implicated as a causitive agent, for producing high blood pressure in various mammalian species, such as the rat, dog, and man. The compounds disclosed in this application inhibit the action of AII at its receptors on target cells and thus prevent the increase in blood pressure produced by this hormone-receptor interaction. The present application discloses a method for the improvement of insulin sensitivity by administering an angiotensin II receptor antagonist, such as a substituted imidazole of formula I, to a species of mammal with hypertension due to angiotensin II. Administration of an angiotensin II receptor antagonist, such as a substituted imidazole of formula I, with a diuretic, such as furosemide or hydrochlorothiazide; either as a stepwise combined therapy (diuretic first) or as a physical mixture, enhances the antihypertensive effect of the compound, while also improving the insulin sensitivity of the patient. wherein R1 is hydrogen, nitro or amino; R2 is phenyl, furyl or thienyl optionally substituted by halogen, lower alkyl, lower alkoxy or di-lower alkylamino; R3 is hydrogen or lower alkyl and X is halogen; and their physiologically acceptable salts.

CHAPTER 9. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for heart transplant. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP).
152
Heart Transplant
Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult™ Mosby’s Drug Consult™ database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to heart transplant by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “heart transplant” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for
Researching Medications
153
marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for heart transplant: •
Imciromab pentetate (trade name: Myoscint) http://www.rarediseases.org/nord/search/nodd_full?code=780
If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists19 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.20 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.21 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
19 Adapted 20
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 21 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
163
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on heart transplant can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to heart transplant. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to heart transplant. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “heart transplant”:

ay=HeartLung Organ Facts Source: United Network for Organ Sharing http://www.transplantliving.org/OrganFacts/default.aspx You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on heart transplant. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to heart transplant. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to heart transplant. By consulting all of associations
172
Heart Transplant
listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with heart transplant. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about heart transplant. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “heart transplant” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “heart transplant”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “heart transplant” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “heart transplant” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.22
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Colloidal: Of the nature of a colloid. [EU] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.

The decreased blood flow may be due to narrowing of the coronary arteries (coronary arteriosclerosis), to obstruction by a thrombus (coronary thrombosis), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (myocardial infarction).
