Myeloid Derived Suppressor Cells Are Induced after Transplantation and Home to the Transplanted Kidney
Surgery and Immunology, University of Maryland, Baltimore, MD.
BACKGROUND: Myeloid-derived suppressor cells (MDSCs) are a naturally occurring, heterogeneous population of highly immunosuppressive cells which expand in response to inflammatory conditions such as cancer.…2018 American Transplant Congress
Anti-Thymocyte Globulin Directly Binds and Functionally Inhibits Allo-Regulatory Myeloid Derived Suppressor Cells
Surgery and Immunology, University of Maryland, Baltimore, MD.
BACKGROUND: Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of naturally occurring, immunosuppressive cells that may be exploitable in transplantation.There are only a few incomplete…2018 American Transplant Congress
Re-Endothelialization of Liver Xenografts Utilizing Human Endothelial Cells
1Surgery, University of Maryland, Baltimore, MD; 2Pathology, University of Maryland, Baltimore, MD.
Introduction:Acute antibody mediated rejection due to preformed antibodies present in human serum remains a hurdle to successful xenotransplantation. Xenograft vascular endothelium represents the initial site…2018 American Transplant Congress
Immune Profiling in Highly Sensitized Kidney Transplant Recipients
Surgery, McGill University, Montreal, Canada.
Introduction: Highly sensitized patients (HSP) express foreign HLA antibodies and have poor graft survival due to higher incidences of graft rejection as compared to non-sensitized…2018 American Transplant Congress
Origin and Traffic of Donor-Derived Extracellular Vesicles during Allo-Sensitization
The idea that donor dendritic cells (DCs) transplanted with the grafts and mobilized to draining lymphoid tissues (dLTs) present donor MHC molecules to allo-reactive naïve…2018 American Transplant Congress
Searching for Recipient-HLA Class II and Donor-HLA-Derived Peptide Complexes Inducing Protective Effect against De Novo Donor-Specific HLA Antibodies Formation in Kidney Transplantation
De novo donor-specific HLA antibodies (dnDSA) are recognized as a risk factor for late deterioration of renal allograft function. dnDSA production occurs via the indirect…2018 American Transplant Congress
Donor Deficiency of RIP3 Phosphokinase Activity Shortens Cardiac Allograft Survival in the Setting of Costimulation Blockade
Surgery, Duke University, Durham, NC.
Receptor-interacting protein kinase 3 (RIP3) is critical for necroptosis in the setting of inflammation. It has been shown that kidney and heart allografts deficient in…2018 American Transplant Congress
Delayed Achievement of Therapeutic Tacrolimus Levels after Renal Transplantation is Not Associated with Increased Incidence of Early Acute Rejection: Single-Center Results
Division of Transplant Surgery, Department of Surgery, University of Washington, Seattle, WA.
Induction therapy followed by maintenance with a calcineurin inhibitor aims to minimize the incidence of early rejection and optimize the potential for allograft function. However…2018 American Transplant Congress
Enrichment of Endogenous Donor-Reactive Tregs in the Spleen and Graft during Transplantation Tolerance is the Result of Treg Proliferation and Conversion from Tconv
Surgery and Medicine, University of Chicago, Chicago, IL.
Foxp3+ regulatory T cells (Tregs) are critical mediators of immune tolerance and are absolutely required for allograft tolerance in animal models. In addition, clinical trials…2018 American Transplant Congress
Identification of Human SIRPa Diversity That Could Regulate Innate Allorecognition
Innate allorecognition is a process by which myeloid cells, such as monocytes, distinguish syngeneic from allogeneic cells. Monocytes that recognize donor cells as non-self differentiate…
