Myeloid AXL Promotes Cardiac Allograft Vasculopathy
*Purpose: Cardiac Allograft Vasculopathy (CAV) is a significant contributor to long term transplant rejection, despite advances in immunotherapy. Reactivity to alloantigen presentation may occur by…2019 American Transplant Congress
Heart En Bloc Thymus Cotransplantation in NHPs
*Purpose: Tolerance of isolated cardiac allografts has never been achieved in NHPs. We investigated whether a cotransplanted, vascularized, donor thymus could induce tolerance of a…2019 American Transplant Congress
Murine Cmv Infection Impairs Transplantation Tolerance: A Critical Role Of Intragraft Anergic Cd4 T Cells
1Medicine, Duke University, Durham, NC, 2Pathology, Northwestern University, Chicago, IL
*Purpose: It is well known that certain infections can impair the stability of transplantation tolerance in recipients who had prolonged functional grafts, resulting in graft-loss.…2019 American Transplant Congress
Predicted Indirectly Recognizable H L A Epitopes Are Associated with T-cell Mediated Rejection among Kidney Transplant Recipients with Preformed and De Novo Donor-Reactive T-cells
*Purpose: Very recently Predicted Indirectly ReCognizable HLA Epitopes (PIRCHE) have been suggested to demonstrate early and late effects on kidney allograft outcomes. The association between…2019 American Transplant Congress
Regulating T Cell Responses by Forced Transgenic Expression of Decay-Accelerating Factor
1Icahn School of Medicine at Mount Sinai, New York, NY, 2Cleveland Clinic, Cleveland, OH
*Purpose: Decay-accelerating factor (DAF, CD55) is a cell surface expressed, glycophosphatidylinositol-(GPI)-anchored, complement regulator. Previous studies showed that during cognate T cell/antigen presenting cell (APC) interactions…2019 American Transplant Congress
SIRPα Typing as a Potential Tool for Risk Stratification in Kidney Transplantation
Transplant Immunology Laboratory, Northwestern University, Chicago, IL
*Purpose: To determine if mismatches in the SIRPα receptor, associated with initiate innate alloresponses in animal models, may impact human kidney transplantation outcome.*Methods: To avoid…2019 American Transplant Congress
MDSCs Prolong Allogeneic Cardiac Graft Survival by Regulating Interferon Type 1 Signaling
*Purpose: We previously demonstrated that donor-derived regulatory dendritic cells (DCreg), contrary to recipient derived DCreg, promote antigen-specific allograft protection. As myeloid-derived suppressor cells (MDSC) show…2019 American Transplant Congress
The Impact of Biological Behavior of Allograft Infiltrating Lymphocytes during Early Phase
Gastroenterological Surgery I, Hokkaido University, Sapporo, Japan
*Purpose: The graft infiltrating lymphocytes (GILs) build an immunological microenvironment locally. Reportedly the GILs within 72hrs posttransplantation do not attack allograft, but may prevent from…2019 American Transplant Congress
IL-1β and IL-6 Facilitate T Cell Reconstitution in Heart Allograft Recipients Treated with Anti-Thymocyte Globulin
Inflammation and Immunity, Cleveland Clinic, Cleveland, OH
*Purpose: Antibody-mediated lymphocyte depletion is used in solid organ and stem cell transplantation. However, T cell reconstitution after lymphoablation may lead to acute rejection and…2019 American Transplant Congress
Withaferin A Shifts Circulating Lymphocytes toward Protective T Cell Subsets and Prolongs Islet Allograft Survival in a Mouse Transplant Model
*Purpose: : Immunosuppression protocols improve the efficacy of allogeneic islet transplantation. However, decline in islet graft function and toxicities imposed by current immunosuppressant drugs remain…
