  1. 1. Implantation-Site Dependent Differences in Engraftment and Function of Transplanted Pancreatic Islets

    Author : Joey Lau; Per-Ola Carlsson; Leif Jansson; Carina Carlsson; Caroline Kampf; Annika Tibell; Uppsala universitet; []
    Keywords : Cell biology; Type 1 diabetes; pancreatic islets; human islets; islet transplantation; vascular engraftment; revascularization; implantation-site; microenvironment; vascular density; insulin release; pro insulin biosynthesis; glucose oxidation; Cellbiologi;

    Abstract : Transplanting pancreatic islets into the liver through the portal vein is currently the most common procedure in clinical islet transplantations for treating patients with brittle type 1 diabetes. However, most islet grafts fail within a 5-year period necessitating retransplantation. READ MORE

  2. 2. Cytokine regulation of pancreatic -cell function with special reference to the pathogenesis of type 1 diabetes

    Author : Johnny Sternesjö; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; insulin secretion; cytokines; nitric oxide; streptozotocin; NOD mice; proteasome; nuclear factor-kappaB; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Cytokines produced by inflammatory cells have been implicated in the pathogenesis of type 1 diabetes. The overall aim of the present work was to test how different cytokines, supposed to be present in the insulitic lesion, could influence the function of islets of Langerhans. READ MORE

  3. 3. The Microvasculature of Endogenous and Transplanted Pancreatic Islets : Blood Perfusion, Oxygenation and Islet Endocrine Function

    Author : Richard Olsson; Per-Ola Carlsson; Leif Jansson; Arne Andersson; Thomas Linn; Uppsala universitet; []
    Keywords : Cell biology; diabetes mellitus; pancreatic islets; islet transplantation; vascular engraftment; islet microcirculation; oxygenation; blood flow; protein biosynthesis; Cellbiologi;

    Abstract : Type 1 diabetes mellitus affects millions of people worldwide. Islet transplantation is a minimal invasive surgical procedure that restores euglycemia and halts the progression of diabetic complications. However, despite transplantation of islets from multiple donors most patients reverse to hyperglycemia within five years. READ MORE

  4. 4. Proislet Amyloid Polypeptide (proIAPP) : Impaired Processing is an Important Factor in Early Amyloidogenesis in Type 2 Diabetes

    Author : Johan F. Paulsson; Gunilla Westermark; Christer Betsholtz; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthesis amyloid; Genetics amyloid; Metabolism amyloid; Islets of Langerhans; Proprotein convertases; Posttranslation protein processing; Medical cell biology; Medicinsk cellbiologi;

    Abstract : Amyloid is defined as extracellular protein aggregates with a characteristic fibrillar ultra-structure, Congo red affinity and a unique x-ray diffraction pattern. At present, 25 different human amyloid fibril proteins have been identified, and amyloid aggregation is associated with pathological manifestations such as Alzheimer’s disease, spongiform encephalopathy and type 2 diabetes.
