Long-Term Islet Xenograft Survival Requires Effective Control of Early Xenogeneic IL-17 Response and Late Xenogeneic IFN-γ Response.
Introduction: Tolerance induction for xenogeneic islet transplant remains a challenge. We have previously shown that peri-transplant infusion of donor cells treated with 1-ethyl-3-(3'-dimethylaminopropyl)-carbodiimide (ECDI) is…2016 American Transplant Congress
NK Cells Are Required in B-Cell Dependent, Antibody Mediated Islet Transplant Tolerance.
Dept of Surgery, Transplant Surgery Division, Massachusetts General Hospital, Boston, MA.
Immunologic tolerance to islets has been achieved in various rodent models using antibodies directed at CD45RB and Tim-1. We have shown that this tolerance mechanism…2016 American Transplant Congress
Successful Human-to-NonHuman Primate Pancreatic Islet Intraportal Xenotransplantation Using a Human Allo-Based Immunosuppression Regimen and Its Potential Pre-Clinical Application.
Intraportal pancreatic islet cell transplantation is a successful treatment for type-1 diabetes (T1DM) in humans. Unfortunately, the lack of donor pancreatic organs is a major…2016 American Transplant Congress
Prolongation of Graft Survival by Anti-TIM1 Is Specifically Mediated by IL-10+ Bregs and Is Not Dependent on IL-35 or Plasma Cell Differentiation.
In B cell-deficient mice, prolonged islet allograft survival (GS) mediated by anti-TIM1 depends on transfer of IL-10 competent B cells. However, such regulatory B cells…2016 American Transplant Congress
Validation of the Newly Developed North America Islet Donor Scoring System in the Medium Volume Islet Transplant Center.
Background.North America Islet Donor Scoring (NAIDS) system has been recently developed for selection of the optimal pancreas donor based on analysis of the results from…2016 American Transplant Congress
B Lymphocytes Prevent Transplantation Tolerance in NOD Mice by Limiting CD4 Treg Function.
Pediatrics, Vanderbilt University, Nashville, TN.
IntroductionType 1 Diabetes is a significant barrier to islet transplant as grafts are subject to both alloimmunity and recurrent autoimmunity. No better is this clinical…2016 American Transplant Congress
The IFN-Gamma-Inducible Protein (IP-10/CXCL10) Is a Promising Target to Improve Endocrine Function Following Islet Transplantation.
A significant mass of transplanted islets is lost very early due to an inflammatory reaction. CXCL10 is a chemokine that is highly expressed in islets…2016 American Transplant Congress
Characterization of Human Islet Transplant Specific Exosomes in a Xenoislet Transplantation Model.
Department of Surgery, University of Pennsylvania, Philadelphia, PA.
Background: There is a critical need for biomarker platforms for monitoring transplant rejection. We propose that transplant tissues release donor specific exosomes into recipient blood/…2015 American Transplant Congress
CD3+CD4+ROR gamma t+ TH17 Cells Do Not Play a Critical Role in Islet Allograft Rejection
Medicine, The Transplant Institute, Beth Israel Deaconess Medical Center, Boston, MA.
We have developed a “color-coded” adoptive transfer model for T cell subset identification that enables serial analysis of islet allograft infiltrating yellow induced regulatory T…2015 American Transplant Congress
Beneficial Effects of Controlling Peritransplant Inflammation in Total Pancreatectomy With Islet Autotransplantation: A Single Center Experience With Large Cohort of Patients
Background: Total pancreatectomy with islet autotransplantation (TPIAT) is an effective surgical treatment for patients with intractable chronic pancreatitis (CP). We recently reported that significant mass…
