Assessment of Simple Indices Based on a Single Fasting Blood Sample in Search for an Optimal Tool to Estimate Beta Cell Function After Islet Transplantation.
Background:Precise yet logistically feasible evaluation of beta-cell function is extremely important after islet allotransplantation. We investigated the utility and possible limitations of indices using only…2017 American Transplant Congress
Measurement of Dissolved Oxygen by 19F MRI of Microcapsules Implanted IP in Non-Human Primates.
Since our encapsulated NHP islet allografts and porcine islet xenografts fail after i.p. transplantation in immunosuppressed NHPs without a cellular or humoral immune response, we…2017 American Transplant Congress
IP-10 Monoclonal Antibody Treatment Suppresses Inflammatory Components of IBMIR and Improves Pancreatic Islet Graft Function.
Introduction: An instant blood-mediated inflammatory response (IBMIR) causes acute loss of pancreatic islets. Interferon gamma-induced protein 10 (IP-10) is a key proinflammatory chemokine that may…2017 American Transplant Congress
Bioengineering Human Islets to Form Peri-Islet Vessels from Intraislet Endothelial Cells for Improving Human Islet Function.
Native islets in the pancreas have a rich vascular supply however, the current islet isolation technique completely severs the vasculature to islets. As such, these…2017 American Transplant Congress
Recognition of Islet Xenografts In Vivo by Non-Obese Diabetic (NOD) Insulin-Specific CD4 T Cells.
Surgery and Immunology, University of Colorado Denver, Aurora, CO
Xenogeneic islet transplantation has been one ongoing goal for treating autoimmune Type 1 diabetes. Autoimmune diabetes involves a T cell response restricted to the host…2017 American Transplant Congress
Immunosuppressive Role of Pancreas Derived Mesenchymal Stem Cells.
BackgroundThe Edmonton protocol revived islet transplantation therapy for Type-1 Diabetic patients. However, Long-term islet function still remains a challenge. Immunosuppression used after islet transplantation contributes…2017 American Transplant Congress
Islet Rejection in Autoimmune NOD Mouse Recipients: Implications for Stem Cell Therapies.
Several efforts are ongoing to use stem cell precursors to generate islet-like tissues suitable for transplantation in autoimmune Type 1 diabetic (T1D) recipients. During the…2017 American Transplant Congress
Thrombalexin and Mirococept Synergistically Reduce IBMIR in a Porcine to Rhesus Xenoislet Model.
Introduction: Early activation of coagulation and complement are important factors in the initiation of instant blood mediated inflammation (IBMIR) in xenoislet models. Two novel 'cytotopic'…2017 American Transplant Congress
Next-Generation Sequencing-Based Exosome MicroRNA Profiling for Specific Identification of Islet Damage.
Introduction: A significant mass of intraportally transplanted islets undergo damage due to various stress conditions including hypoxia and inflammation. Development of innovative ultrasensitive tests to…2017 American Transplant Congress
Long-Term Drug-Free Survival of Tiny Cynomolgus Islet Allografts.
Following upon highly beneficial effects observed with short-term alpha 1-antitrypsin (AAT) treatment in the marginally sized autologous cynomolgus islet transplant model, we are testing the…
