CD47 Innate Immune Checkpoint Enhances Islet Engraftment Following Intraportal Transplantation by Mitigating Instant Blood Mediated Inflammatory Reaction
*Purpose: Transplantation of islets into hepatic portal vein is associated with significant islet mass loss immediate post-transplantation. Instant blood mediated inflammatory reaction (IBMIR), characterized by…2019 American Transplant Congress
Microfluidic Study Analyzing the Effect of Immediate-Release and Extended-Release Tacrolimus on Islet Function
*Purpose: The purpose of this analysis was to quantify the impact of 2 tacrolimus pharmacokinetic profiles on functional changes within human islet cells using a…2019 American Transplant Congress
Prevention of Diabetes in the NOD Mice Reconstituted with Bone Marrow Cells from Allogeneic CD4 Knockout, CD8 Knockout or B-Cell Knockout B6 Mice
University of Louisville, Louisville, KY
*Purpose: Type 1 diabetes (T1D) is an autoimmune disorder characterized by destruction of the pancreatic beta cells by both humoral- and cell-mediated immune mechanisms. Transplantation…2019 American Transplant Congress
Islet Stress Leads to Increased Release of Exosomes That Stimulate Immune Cell Response
*Purpose: Islet dysfunction and death caused by isolation procedures, immune attack and hypoxia significantly affect islet transplantation outcomes. Non-invasive monitoring of islet stress and damage…2019 American Transplant Congress
Xenorejection of Porcine Islets in Humanized Mice is Dominated by a Human Th17 Cytokine Immune Response
*Purpose: We have previously shown that interleukin(IL)-17 producing CD4 T cells (Th17 response) dominate in the early anti-donor immune responses of a pig-to-mouse xenogeneic model…2019 American Transplant Congress
Pancreatic Extracellular Matrix Improves Human Islet Culture and Function In Vitro
Virginia Commonwealth University, Richmond, VA
*Purpose: Islet transplantation is a thriving therapy for patients with Chronic Pancreatitis and Type-1 Diabetes. Within the pancreas, the islets are surrounded by Extracellular Matrix…2019 American Transplant Congress
Improvement of the Outcome of Clinical Islet Transplantation Depending on the Era in Japan
*Purpose: Islet transplantation (ITX) is an ideal treatment for type 1 diabetic patients. In this paper, we compared the outcome of ITX depending on Era…2019 American Transplant Congress
Human Mesenchymal Stem Cells Inhibits Hypoxia-Induced Islets Apoptosis via Regulation of Autophagy
The Third Xiang Ya Hospital,Central South University, ChangSha, China
*Purpose: Xenotransplantation of porcine islets has been an emerging and effective option for clinicians to treat type 1 diabetes recently. Comparing with other damage, hypoxic…2019 American Transplant Congress
Microparticle Delivery to Lymph Nodes Induces Specific Suppression to Prolong Islet Survival
1Surgery, U. Maryland, Baltimore, MD, 2U.Maryland, Baltimore, MD, 3U. Maryland, College Park, MD
*Purpose: Microparticles (MP) loaded with peptide antigen plus other immune signals and delivered directly into lymph nodes (LN) can result in either proinflammatory or antiinflammatory…2019 American Transplant Congress
Exosomes Carry Stress and Damage Specific miRNAs during Peritransplant Period in TPIAT
*Purpose: Innate inflammation and hypoxia during peritransplant period significantly affect survival of islet grafts. Markers that can identify stress and/or damage during this early period…
