The Role of CD47/SIRPα and CD47/TSP-1 Pathways in Pig-to-Baboon Kidney Transplantation Using hCD47 Transgenic Kidneys
*Purpose: We have recently reported that both CD80 upregulation and the degradation of SMPDL-3b on glomerular podocytes are involved in the development of post kidney…2019 American Transplant Congress
Xenorejection of Porcine Islets in Humanized Mice is Dominated by a Human Th17 Cytokine Immune Response
*Purpose: We have previously shown that interleukin(IL)-17 producing CD4 T cells (Th17 response) dominate in the early anti-donor immune responses of a pig-to-mouse xenogeneic model…2019 American Transplant Congress
Kidney Xenotransplantation from Genetically Engineered Pigs to Baboons with FDA-Approved Immunosuppressive Therapy
*Purpose: Genetically-engineered pigs might present a solution to the critical shortage of organs for clinical transplantation. The aims of this study were to evaluate the…2019 American Transplant Congress
Donor-Specific Tregs Prolong Peripheral Chimerism in Baboons Receiving GalTKO hCD47-tg Porcine Peripheral Blood Stem Cells
*Purpose: We have previously evaluated the ability of transplantation of polyclonal expanded recipient T regulatory cells to prolong xenogeneic chimerism and skin grafts after transplantation…2019 American Transplant Congress
Utilizing Ides To Eliminate Residual Antibodies Targeting Xenografts
Massachusetts General Hospital, Boston, MA
*Purpose: A significant hinderance to the successful use of xenotransplantation has been the presence of preformed antibodies against the donor antigens, known as xenoantigens. Using…2019 American Transplant Congress
TCR Transgenes to Understand Human Xenotolerance Induction
Columbia Center for Translational Immunology, New York, NY
*Purpose: Swine thymus transplantation is a promising approach to clinical tolerance for pig-to-human xenotransplantation. In humanized mice, a swine thymus graft supports de novo selection…2019 American Transplant Congress
Islet Xenotransplantation: A Quest for Clinically Available Immunosuppression Regimens
1Surgery, Duke University, Durham, NC, 2University of Massachusetts, Worcester, MA
*Purpose: Porcine islet xenotransplantation has progressed significantly in non-human primate (NHP) studies. However, all successful NHP studies have relied upon immunosuppressive regimens that utilize drugs…2019 American Transplant Congress
Inhibition of Sialidase Activity and Galectin Binding Reduces Xenogeneic Neutrophil-Endothelial Adhesion
*Purpose: Immediate neutrophil sequestration occurs despite genetic modifications (Gal-a-1-3 galactosyl transferase knock out; human CD46 complement regulatory gene addition) to pig donor organs. Sialic acids…2019 American Transplant Congress
Effects of Static Subnormothermic Preservation of Extended Warm Ischemic Porcine Kidneys Assessed by Ex-Vivo Machine Perfusion and Renal Transplant Model
Center for Advanced Biomedical Science and Swine Research, Kagoshima University, Kagoshima, Japan
*Purpose: The donation after circulatory death (DCD) donors has the potential to match the increasing need for transplantable organs, however, DCD kidneys have a higher…2019 American Transplant Congress
Expression of Prostaglandin E2 Receptors Track with Rejection in Porcine Kidney Transplants
*Purpose: Prostaglandin E2 (PGE2) is generated from arachidonic acid via cyclooxygenase-2 (COX2) and is known to modulate the immune response via its receptors: EP1, EP2,…
