Cognate Events in Antibody- Vs. T Cell-Mediated Rejection: A Molecular Perspective
AIM: The cognate event in antibody-mediated rejection (ABMR) is NK cell FcR engagement; T cell mediated rejection (TCMR) uses TCR engagement. Understanding the molecular changes…2015 American Transplant Congress
Blocking CD40/CD154 Co-Stimulation Prevents Acute Antibody-Mediated Renal Allograft Rejection Induced by Memory CD4 T Cells
Immunology, The Cleveland Clinic, Cleveland, OH.
Immunosuppression-resistant alloreactive memory CD4 T cells induce robust responses against organ transplants. In murine heart allograft recipients donor-reactive memory CD4 T cells provide help for…2015 American Transplant Congress
Impact of Pretransplant Pregnancy On Immunization and Immunologic Outcome in Kidney Transplantation
BACKGROUND:The detailed impact of pretransplant pregnancy on HLA alloimmunization and outcome after kidney transplantation is so far not well known.PATIENTS AND METHODS:A retrospective single center…2015 American Transplant Congress
Quantifying the Survival Benefit of HLA-Incompatible Kidney Transplantation: A Multi-Center Study
Surgery, Hopkins, Baltimore, MD.
A single center study has demonstrated a two-fold survival benefit of incompatible live donor kidney transplant (ILDKT) compared to remaining on dialysis. We sought to…2015 American Transplant Congress
Maintaining Immunosuppressive Treatment After Early Allograft Nephrectomy Does Not Reduce the Risk of Anti-HLA Allo-Sensitization
BackgroundAnti-HLA immunization is greatly increased after early kidney-allograft failure, even if the graft is removed within a few hours post-transplantation. The aim of our study…2015 American Transplant Congress
Distinct Subtypes of Rejection in a Novel Non Human Primate Model of Sensitization
[Background] Preformed and newly formed alloantibody post transplantation (TX) can significantly deteriorate graft survival. Patterns of humoral rejection in sensitized patients varies significantly due to…2015 American Transplant Congress
Furthering the Link Between Ischemia and Immunity: Development of New Antibody Following Prolonged Delayed Graft Function
Introduction The purpose of this study is to examine the relationship between prolonged ischemia (delayed graft function - DGF) and the development of de novo…2015 American Transplant Congress
Etiology, Incidence and Outcomes of the Highly Sensitized Kidney Transplant Patient
University of Wisconsin, Madison, WI.
Background: Sensitization to HLA antigens is a major barrier to kidney transplantation. We sought to determine the etiology, incidence and outcomes of kidney transplants performed…2015 American Transplant Congress
Detection of Donor Specific HLA-Ab (DSA) Against Native HLA Molecules Expressed On Donor Cell Surface to Eliminate False Positive DSA in Luminex Single Antigen Beads (LMX-SAB)
Pathology, Stanford University, Palo Alto, CA.
Introduction:The LMX-SAB has been extensively used for DSA virtual crossmatch (VXM) to predict actual crossmatch (AXM). The extreme pH and harsh chemical reaction conditions used…2015 American Transplant Congress
Antibody-Induced Platelet Activation Increases Allograft Hyaluronan Fragmentation
Antibodies to MHC class I antigens have been shown to activate endothelial cells to release von Willebrand factor (vWf) and P-selectin from storage granules. These…
