B-Cell Tolerance to Donor Alloantigens
Pre-existing panel-reactive antibodies and development of donor-specific alloantibodies are known to play important roles in graft dysfunction and deterioration. Preventing and/or eliminating alloantibody responses would…2015 American Transplant Congress
Elective Allograft Nephrectomy After Transplant Failure
University Hospitals, Transplant Institute, Cleveland, OH.
Background/Methods: Because of high rates of allograft intolerance and alloantibody sensitization after kidney transplant failure, we undertook a pilot study of elective allograft nephrectomy (ENx)…2015 American Transplant Congress
Natural History of Anti- Human Leukocyte Antigen Antibodies After Hear Transplant
Cedars-Sinai Heart Institute, Los Angeles, CA.
Purpose: The natural history of the production of circulating antibodies has not yet been clearly established. Recent technology has allowed for the improved detection of…2015 American Transplant Congress
Complement Inhibition Via the Lectin Pathway Improves Experimental Cardiac Graft Survival
Purpose: While complement activation via both the classical as well as the lectin pathway is believed to contribute to allograft loss, their relative contribution is…2015 American Transplant Congress
MHC-Class-II Specific Sensitization in a Non-Human Primate Model of Sensitzation
1Emory University, Atlanta, GA; 2Medical University Vienna, Vienna, Austria.
[Background] Sensitization before transplantation and de novo alloantibodies affect a significant number of patients awaiting kidney transplantation. The type of anti-HLA antibody varies with subgroups…2015 American Transplant Congress
Outcome of Bortezomib/Plasmapheresis for the Sensitized Patient Awaiting Heart Transplant
Cedars-Sinai Heart Institute, Los Angeles, CA.
Purpose: Allosensitization of patients (pts) awaiting heart transplantation is a significant challenge as it prolongs the time to transplant, increases wait-list mortality and increases risk…2015 American Transplant Congress
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…
