Epstein Barr Virus DNA Integration in B Cell Lymphomas of Post-Transplant Lymphoproliferative Disorder
Surgery, Division of Abdominal Transplant, Stanford University School of Medicine, Stanford, CA
*Purpose: Epstein Barr virus-positive (EBV+) B cell lymphomas can arise in immunosuppressed individuals, such as organ transplant recipients in the context of post-transplant lymphoproliferative disorder…2019 American Transplant Congress
Role of MHC Class II in B Cell and Regulatory T Cell Development
Surgery, Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA
*Purpose: Therapies involving CD4 regulatory T cells (Tregs) are promising approaches to mitigate graft rejection and autoimmunity. Understanding of the activation mechanisms that initiate Treg…2019 American Transplant Congress
BCMA Expression by Alloreactive B Cells Increases during De Novo Alloantibody Responses
Comprehensive Transplant Center, Cedars-Sinai Med Ctr, Los Angeles, CA
*Purpose: BCMA(TNFRSF17) belongs to tumor necrosis factor receptor superfamily. It is selectively expressed during B/plasma cell differentiation while being nearly absent on naive and memory…2019 American Transplant Congress
A Step-Wise Desensitization Using Rituximab&Bortezomib Combined with Antithymocyte Globulin for Highly Sensitized Kidney Transplant Candidates
Hiroshima University, Hiroshima, Japan
*Purpose: In highly HLA sensitized patients, both memory B and T cells responding to donor-specific HLA in addition to plasma cells secreting anti-HLA Abs are…2018 American Transplant Congress
Prolonged Cold Ischemia Storage of Renal Allografts Shifts DSA Specificity and Enchances Glomerular Injury
Immunology, Cleveland Clinic, Cleveland, OH.
Prolonged cold ischemia storage (CIS) of donor organs is a major risk factor for acute and chronic graft injury. The goal of this study was…2018 American Transplant Congress
Elevated Levels of CD19+ B Cells before or after Rituximab Administration is a Risk Factor for the Early Rejection of a Living Kidney Transplant
1Nephrology, Ohkubo Hospital, Tokyo, Japan; 2Urology, Ohkubo Hospital, Tokyo, Japan.
[Introduction]Rituximab (RTX) is used for desensitization in highly sensitized patients, such as those undergoing ABO-incompatible (ABOi) kidney transplantation. Although RTX is generally effective, some patients…2018 American Transplant Congress
In Vivo Administration of Plerixafor and Bortezomib Results in Bone Marrow Plasma Cell Mobilization and Death While Inducing Biphasic Plasma Cell Apoptosis in Peripheral Blood
1U Cincinnati, Cincinnati; 2Cincinnati Children's, Cincinnati; 3Duke, Durham.
Bone marrow (BM) plasma cells (PC) secreting HLA antibody (Ab) remain a persistent reservoir of donor specific Ab and present a significant hurdle to allograft…2018 American Transplant Congress
Genomic Modifications Associated with Epstein Barr Virus+ Post-Transplant Lymphoproliferative Disorder
Epstein Barr Virus (EBV) is nearly ubiquitous in the human population, yet EBV infection is typically asymptomatic. Nevertheless, immunosuppressed transplant recipients are susceptible to EBV+…2018 American Transplant Congress
Pancreas Transplant for Type 2 Diabetes is Associated with Preserved Function, but Impaired Glucose Tolerance: A Comparative Analysis
Multi-Organ Transplant Program, Toronto General Hospital, Toronto, ON, Canada.
Background: The indications and outcomes of pancreas transplantation for type 2 diabetes mellitus (T2DM) remains controversial. The aim of this study was to compare the…2018 American Transplant Congress
Analysis of Circulating CD38+/CD138+ Plasma Cells during Development of De Novo Donor Specific Antibody Responses
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor specific antibodies (DSA) that emerge following transplantation are indicative of allogenic sensitization and a predisposing factor for antibody mediated rejection. Though various methods…
