Epstein Barr Virus Modulates Host Cell MicroRNA-194 to Promote IL-10 Production in B Cell Lymphomas
Surgery/Division of Abdominal Transplant, Stanford University School of Medicine, Stanford, CA.
Epstein Barr virus (EBV) infection is associated with the development of post-transplant lymphoproliferative disorder (PTLD) which can manifest as aggressive B cell lymphomas in transplant…2015 American Transplant Congress
CTLA4Ig Administered During T-Cell Priming Negates de novo Alloantibody Responses and Modulates Recall Antibody Production
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Arcadia, CA.
Background CTLA4Ig (Belatacept) is a novel anti-rejection therapy aimed at costimulatory blockade. Clinical data suggest that post-transplant alloantibody formation is also reduced in patients treated…2015 American Transplant Congress
Long-Term Analysis of a Placebo-Controlled Trial of C1-INH for Prevention of Antibody-Mediated Rejection
Kidney Transplant, Cedars-Sinai Medical Center, Los Angeles, CA.
Introduction: Desensitization (DES) strategies focus primarily on antibody reduction using IVIG, rituximab ± PLEX to prevent DSA-induced antibody-mediated rejection (ABMR) and rebound B-cell activity. Recently,…2015 American Transplant Congress
B Cell MicroRNA as Biomarkers for Epstein-Barr Virus Associated Post-Transplant Lymphoproliferative Disorder
Surgery/Division of Abdominal Transplant, Stanford University School of Medicine, Stanford, CA.
Post-transplant lymphoproliferative disorder (PTLD) is a potentially fatal complication of organ transplantation and is commonly associated with Epstein Barr virus (EBV) infection. EBV viral loads…2015 American Transplant Congress
Characterization of a Nude Mouse Model of Allosensitization Conditioned by Adoptive Transfer of Follicular T Helper Cells
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
Background Follicular T helper (Tfh) cells play a critical role in follicular B cell activation and maturation during antibody responses to allograft. Here we report…2015 American Transplant Congress
Noncanonical Anergic Alloreactive B Cells in Transplantation Tolerance
Depart of Surgery, University of Chicago, Chicago.
The observation that operationally tolerant patients (TOL) display higher numbers of blood B cells and a B cell gene signature compared to stable kidney allograft…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…2015 American Transplant Congress
Preemptive Rituximab Therapy of Epstein-Barr Virus (EBV) Infection to Prevent Post-Transplant Lymphoproliferative Disease (PTLD) After Pediatric Solid Organ Transplantation (SOT)
Purpose: More than 90% of pediatric PTLD after solid organ transplantation is associated with EBV infection. Reduction in immunosuppression is the first step to prevent…2015 American Transplant Congress
TGFβ Production By B Cells Is Critical for Transplant Tolerance Induction
Regulatory B cells (Bregs) have been shown to play a critical role in immune homeostasis and in autoimmunity models. We have recently demonstrated that combined…2015 American Transplant Congress
The Best Regimen With Rituximab for ABO-Incompatible Living Donor Liver Transplantation
Rituximab made a great progress on outcomes of ABO-incompatible living donor liver transplantation (ABO-I LDLT). Although Japanese multicenter study group published efficacy and safety of…
