Allo-Specific Memory B Cell Recall Responses Are Dependent on B Cell Autophagy.
B cells, and in particular, memory B cells (Bmem) are sources of donor specific antibodies (DSA) that cause allograft injury. Understanding requirements for Bmem function/survival…2016 American Transplant Congress
Criteria for the Diagnosis of Microvascular Inflammation (MVI) in Kidney Transplant Biopsies (KTxBx).
The presence of MVI (Banff glomerulitis "g" score and Banff peritubular capillary "ptc" score) in KTxBx, often related to antibody mediated rejection (AMR), is associated…2016 American Transplant Congress
Utilization of Plasmapheresis and High Dose of Immunoglobulins in the Treatment of the High Level of De Novo Donor Specific Antibodies for the Successful Islet Allotransplantation.
Background.Development of donor specific antibodies (DSA) after islet transplantation has been a poor prognostic factor for graft survival, while no intervention is implemented. Here, we…2016 American Transplant Congress
Optimized Flow Cytometry Crossmatch with Increased Sensitivity and Specificity.
The flow cytometry crossmatch (FCXM) is the standard method to prevent hyperacute rejection after transplantation. Surprisingly, few technical improvements have been introduced to the FCXM…2016 American Transplant Congress
Selective Deletion of Notch2 on B Cells Abrogates Alloantibody Production in Fully MHC-Mismatched Cardiac and Skin Transplant Models.
Alloantibody-mediated injury remains a major challenge for the improvement of long-term graft survival and there is no effective therapy to prevent alloantibody generation post-transplant. The…2015 American Transplant Congress
Deceased Donor and Class II Donor Specific Antibody Predict Interface Activity While Increased Age at Time of Biopsy Predicts Fibrosis in Long-Term Pediatric Liver Allografts With Normal Liver Tests: iWITH Clinical Trial
Background: Although multiple single centers have reported deterioration of pediatric liver grafts in the face of normal liver tests, neither risk nor mechanism is understood.Methods:…2015 American Transplant Congress
Notch-1 Inhibition Promotes Immune Regulation in Solid Organ Transplantation
Notch receptor signaling plays a key role in T cell activation and differentiation, though limited data exist on its importance in immune regulation. Herein, we…2015 American Transplant Congress
A Single Center Study on Pregnacy and Allograf Function Outcomes Post Heart Transplant
Heart Transplant, Vanderbilt Medical Center, Nasvhille, TN.
Pregnancy is a special time during a young woman's life, especially more so in those young women who are post heart transplant. The purpose of…2015 American Transplant Congress
Pretransplant Antibodies Against Angiotensin II Type 1 Receptor in Renal Transplantation: Preliminary Data from the KNOW-KT Study
BackgroundThe antibodies (Abs) against angiotensin II type 1 receptor (AT1R) have been suggested as a risk factor for graft failure and acute rejection. However, incidence…2015 American Transplant Congress
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…
