  2. 1. Influence of Islet-derived Factors in Islet Microcirculation and Endocrine Function

    Author : Carl Johan Drott; Per-Ola Carlsson; Leif Jansson; Albert Salehi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; pancreas; blood flow; islet vascularity; islet-derived; TSP-1; ghrelin; CART; irisin; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Diabetes mellitus is a disorder with complex pathology and is frequently associated with vascular complications. In the islet micro milieu locally generated factors may affect both the physiology and the morphology of the tissue. READ MORE

  4. 2. 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

  5. 3. Microcirculation in native and transplanted rodent pancreatic islets with special reference to the influence of diabetes mellitus

    Author : Per-Ola Carlsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; islet microcirculation; microspheres; micropuncture technique; islet blood flow; islet capillary pressure; oxygen tension; transplanted islets; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The aim of the present work was to characterize the islet microcirculation in animal models of type 1 and type 2 diabetes, as well as in islets transplanted to diabetic or normoglycemic recipients. For this purpose, a microsphere technique was evaluated and applied for measurements of islet blood flow in mice. READ MORE

  6. 4. Studies of pancreatic islet microcirculation and insulin secretion in normal and diabetic rats

    Author : Zhen Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : diabetes; islet; insulin; microcirculation; ethanol; blood flow; hypoglycemia; renin angiotensin system; statins;

    Abstract : Type 2 diabetes is increasing globally. The disease is characterized not only by hyperglycemia, but also by insulin resistance with attendant dyslipidemia, hypertension and endothelial dysfunction. These aberrations may result in macrovascular disease, and deeply impact the longevity and quality of life in diabetic patients. READ MORE

  7. 5. Strategies to improve macroencapsulated islet graft survival

    Author : Anne Sörenby; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Chronic immunosuppressive therapy may have severe side-effects. In cell transplantation, the graft can be encapsulated within a membrane chamber, providing a physical barrier against the immune system. The cell graft then becomes dependent on the diffusion of nutrients and oxygen from the surrounding microcirculation. READ MORE
