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…2017 American Transplant Congress
HLA Class II Molecules Partner with TLR4 to Stimulate Endothelial Cell Activation and Proliferation.
Pathology and Laboratory Medicine, University of California Los Angeles, Los Angeles, CA
Background: Transplant recipients developing donor specific HLA antibodies (DSA) are at a higher risk for acute and chronic antibody-mediated rejection (AMR). DSA contribute to the…2017 American Transplant Congress
Non-Human Primate Auto-Immune Responses to Col V, Kα-1Tubulin and Vimentin Are P2X7R Dependent.
1Surgery, University of Wisconsin, Madison, WI; 2Medicine, University of Wisconsin, Madison, WI
Background: Auto-immune responses to Collagen type V (ColV) have been associated with coronary artery disease and lung or heart transplant rejection in humans and murine…2017 American Transplant Congress
Development of Transplant Glomerulopathy in Recipients with Antibody Mediated Rejection: Activation of Inflammatory Pathway Through Renal Poly (ADP-Ribose) Polymerase (PARP).
Activation of PARP is a critical factor in the pathogenesis of various inflammatory and fibrotic process. Thus we aimed to show the integral of PARP…2017 American Transplant Congress
MHC Class II-Peptide Complexes Displayed on Activated T Cells Guide Treg Suppression.
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA
Background: Regulatory T cell (Tregs) therapy remains a promising strategy for minimizing immunosuppression and extending allograft survival. Although Treg suppression requires initial activation through cell…2017 American Transplant Congress
Contemporary Outcomes and Risk Factors of Acute Graft-versus-Host Disease After Liver Transplant.
Gastroenterology and Hepatology, Henry Ford Hospital, Detroit, MI
Introduction:Acute graft-versus-host-disease (GVHD) is a rare complication of orthotopic liver transplant (LT) that has an estimated incidence of 0.1%-2% per year. This complication of OLT…2016 American Transplant Congress
Is C3d-fixing Donor Specific HLA Antibody Detection Really Necessary?
Introduction: Chronic antibody–mediated rejection is the main cause of late kidney graft loss. The identification of donor-specific antibodies (DSA) in the serum is one of…2016 American Transplant Congress
Direct Alloimmunity Is Driven by Recipient APCs Displaying Donor MHC Molecules.
We have studied the trafficking of donor passenger leukocytes and donor MHC presentation in the lymphoid organs of mice having received an MHC-mismatched skin or…2016 American Transplant Congress
An In-Situ Treatment of Donor Skin Induces MARCH1 and Decreases MHC II Expression on Donor Dendritic Cells, Promoting Skin Allograft Acceptance.
Background: Skin transplants are the most immunogenic of all transplants and donor DCs play a crucial role in activating effector alloreactive T cells and initiating…2016 American Transplant Congress
HLA Class II and BK Virus Reactivation in Renal Transplant Recipients.
BK Viremia (BKV) and subsequent BK nephropathy are associated with renal graft loss. The Human Leukocyte Antigen (HLA) region has been implicated in susceptibility to…
