Islet Allotransplantation Into Pre-vascularized Sernova Cell PouchTM – Preliminary Results from the University of Chicago
1Surgery, University of Chicago, Chicago, IL, 2Medicine, University of Chicago, Chicago, IL
*Purpose: Previous first-in-human pilot study showed safety but the conditions did not allow for detectable islet function post-transplantation into the pre-vascularized Sernova Cell Pouches (SCPs)…2021 American Transplant Congress
Evaluation of Preperitoneal Space as an Extrahepatic Transplant Site in Clinical Total Pancreatectomy with Islet Autotransplantation
Baylor University Medical Ctr, Dallas, TX
*Purpose: Total pancreatectomy and intraportal islet autotransplantation (TPIAT) is an effective treatment for patients with refractory chronic pancreatitis. Large volume islet preparations cannot always be…2021 American Transplant Congress
Donor Mhc-independent Islet Rejection in Autoimmune Diabetes: Implications for Stem Cell Therapy
*Purpose: Stem cell technology is an attractive approach for generating insulin-producing cells for transplantation in insulin-dependent diabetes and potentially can be genetically modified. One recent…2021 American Transplant Congress
Targeting Calcineurin/nfatc2 Signaling to Restore Pancreatic Beta-cell Function in Islet Transplantation
1Baylor University Medical Ctr, Dallas, TX, 2Baylor University Medical Ctr, Allen, TX
*Purpose: Pancreatic beta cells dedifferentiate upon exposure to metabolic and inflammatory stress characterized by loss of beta-cell identity genes, expression of beta-cell disallowed genes, and…2021 American Transplant Congress
Exosomal DAMP Proteins Released During Islet Isolation Affects TPIAT Outcomes
Hume Lee Islet Cell Transplantation Lab, Department of Surgery, VCU Health, Richmond, VA
*Purpose: Isolation of islets cause significant stress that results in the release of immunogenic factors called damage-associated molecular patterns (DAMPs) which can induce inflammatory signaling…2021 American Transplant Congress
LacripepTM-like Peptide N-104 Promotes Beta Cell Proliferation in Murine Pancreatic Islets
University of Virginia Health System, Charlottesville, VA
*Purpose: To monitor time-dependent cellular changes, with emphasis on beta cell regeneration, in pancreatic islets following treatment with LacripepTM-like peptide N-104 by mass cytometry. Background:…2021 American Transplant Congress
Islet Isograft Transplantation Improves Insulin Sensitivity in a Murine Model of Type 2 Diabetes
Asan Medical Center, Seoul, Songpa, Korea, Republic of
*Purpose: Type 2 diabetes develops in the presence of chronic overnutrition and genetic susceptibility, and causes insulin resistance and relative insulin deficiency. We hypothesized that…2021 American Transplant Congress
LacripepTM-like Peptide N-104 Increases Insulin Secretion and Promotes Islet Transplantation Outcomes
University of Virginia Health System, Charlottesville, VA
*Purpose: To study if LacripepTM-like peptide N-104 promotes beta-cell stabilization and islet transplantation outcomes. Background: Lacritin is a multifunctional tear protein with prosecretory, prosurvival and…2021 American Transplant Congress
A Small Molecule Inhibitor of Toll-like Receptor-4 TAK-242 Attenuates IBMIR Against Human Islets
1Baylor University Medical Ctr, Dallas, TX, 2Baylor University, Waco, TX
*Purpose: A large portion of grafted islets are lost shortly after infusion due to the instant blood mediated inflammatory reaction (IBMIR). In our previous studies,…2021 American Transplant Congress
Bone Marrow-Derived Mesenchymal Stem Cells Improve Rat Islet Graft Revascularization by Upregulating Isl1
Kidney Transplantation, The First Affiliated Hospital of Xi'an Jiaotong University, Xi An, China
*Purpose: Revascularization of the transplant islet is a crucial step that defines the success rate of patient recovery. Though bone marrow-derived mesenchymal stem cells (BMSCs)…
