Dual Inhibition of PI3K and mTORC2 Causes ERK Hyperactivation Induced by HLA-II Antibody in Human Endothelium
Pathology and Laboratory Medicine, David Geffen School of Medicine, UCLA, Los Angeles, CA.
Background: Endothelial cells (EC) line the inner surface of blood vessels and serve as the interface between recipient circulating blood and the donor allograft. Transplant…2018 American Transplant Congress
The Complexity of HLA-DQ
Northwestern University, Chicago.
Historically, HLA-DQ antigens and antibodies (Ab) were difficult to classify due to the lack of serological typing reagents. However, with the advent of molecular typing…2018 American Transplant Congress
ABO-Incompatibility Lower Incidence of DSA-Induced Antibody-Mediated Rejection
Introduction:Donor-specific anti-HLA antibody (DSA) and Anti-ABO antibody are major barriers for successful kidney transplantation. Limited data are available about the existences of both DSA and…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
Feasibility of a National Class II Matching Strategy for Pediatric Kidney Transplant Candidates
Antibody-mediated rejection (AMR) is a major concern for allograft failure, which could be mitigated by allocation of Class II matched donors. Since children have priority,…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…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…
