Preservation of Pancreatic Islets with Stem Cell Derived CD34+ Vascular Endothelial Progenitor Cells
1Surgery, UCSF, San Francisco, CA, 2Diabetes Center, UCSF, San Francisco, CA
*Purpose: Islet transplantation can cure Type 1 diabetes; however, multiple donors are needed due to extensive perioperative loss of islets when removed from their native…2019 American Transplant Congress
IL-10+ Plasma Cells Are Not Required for Breg Activity and Are Counterbalanced by Novel Pro-Inflammatory Plasma Cells
University of Pittsburgh, Pittsburgh, PA
*Purpose: Classically, B cells differentiate into Ab-secreting plasma cells (PCs; B220lowCD138hiBlimp1+Ig+) providing humoral immunity. B cells can also inhibit or promote immune responses through the…2019 American Transplant Congress
Resolution of Hyperglycemia Following Islet Allograft Transplantation in Non-Immunosuppressed Mice
*Purpose: Kidney allografts are naturally tolerogenic in mice. Certain mouse strain combinations develop tolerance of kidney allografts across full MHC incompatibilities without immunosuppression (e.g. DBA/2…2019 American Transplant Congress
Predicting Metabolic Outcomes in Islet Autotransplantation before Transplantation
Virginia Commonwealth University, Richmond, VA
*Purpose: Total Pancreatectomy with Islet Auto-transplantation (TPIAT) has been actively performed on patients with severe, debilitating pain of chronic pancreatitis. The outcome of islet transplantation…2019 American Transplant Congress
Role of NF-kB in Release of Isletokines via Exosomes in Response to Islet Stress
*Purpose: Human islets are exposed to a range of inflammatory stimuli upon transplantation that leads to poor graft survival. Identifying the various signaling events may…2019 American Transplant Congress
Blockade of IL-1β and TNF-α Does Not Significantly Pose Risk or Affect Outcomes in Patients Infused with Microbial-Positive Autologous Islet Preparations
*Purpose: We recently demonstrated that the combined use of anakinra (IL-1β blocker) and etanercept (TNF-α blocker) improved outcomes of islet autotransplantation after total pancreatectomy (TPIAT).…2019 American Transplant Congress
B Cell IL-4 Signaling Induces the IL-10 Secreting TIM-1+ Bregs and Suppresses T Cell Inflammatory Cytokines
Surgery, Starzl Transplantation Institute, Pittsburgh, PA
*Purpose: TIM-1+ identifies the majority (~75%) of IL-10+ B regulatory cells (Bregs). However, TIM-1+ B cells are also enriched for IL-4+ B effector 2 cells…2019 American Transplant Congress
Fibrosis Scoring Correlates with Progression of Chronic Pancreatitis, Islet Isolation Yields and Transplant Outcomes in Patients Undergoing Islet Autotransplantation
*Purpose: Total pancreatectomy with autologous islet transplantation (TPIAT) is a promising procedure for alleviating pain and maintaining glucose homeostasis in chronic pancreatitis (CP) patients. However,…2019 American Transplant Congress
Long Term Renal Function Following Islet Transplantation in the Clinical Islet Transplantation Consortium
*Purpose: Islet transplantation (IsletTp) is safe and effective treatment of Type 1 diabetes complicated by severe hypoglycemia (Diabetes Care 2016, 39:1230). But the requirement for…2019 American Transplant Congress
Outcomes of Total Pancreatectomyand Islet Autotransplantation, a Single Center Experience
*Purpose: Patients with chronic pancreatitis (CP) suffer from severe pain that greatly reduces their quality of life and often leads to long-term narcotic therapy to…
