  2. 1. Free fatty acids and insulin hypersecretion studied in human islets

    Author : Jing Cen; Peter Bergsten; Miriam Cnop; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; free fatty acids; palmitate; human islets; EndoC-βH1 cells; metformin; sorcin; insulin secretion; mitochondrial respiration; ER stress; human transcriptome array; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Free fatty acid (FFA) levels are increased in many obese subjects. High FFA levels stimulate the pancreatic beta-cells but have negative long-term effects. In obese children with high FFA levels circulating insulin concentration is high early in life but decline with age precipitating the development of type 2 diabetes mellitus (T2DM). READ MORE

  4. 2. Characterization of the Pancreas in Type 1 and Type 2 Diabetes

    Abstract : Diabetes is recognized by hyperglycaemia and polyuria. Complications, reduced quality of life and staggering health-care costs are all derived from the disease. Two subclasses of diabetes are Type 1 diabetes (T1D) and Type 2 diabetes (T2D). READ MORE

  5. 3. 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

  6. 4. Study of DNA methylation in human pancreatic islets

    Author : Elin Hall; Diabetes - epigenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes; epigenetics; DNA mehtylation; human pancreatic islets; insulin secretion;

    Abstract : Today type 2 diabetes is a common disease with a worldwide prevalence of 8.3%. The disease is characterised by hyperglycaemia which is a result of insufficient insulin secretion from the beta-cells in the pancreatic islets as well as an insulin resistance seen in the target tissues.

  7. 5. Inflammatory Mediators and Enterovirus Infections in Human Islets of Langerhans

    Author : Annika Moëll; Gun Frisk; Olle Korsgren; Bo Nilsson; Outi Vaarala; Uppsala universitet; []
    Keywords : Immunology; diabetes; islets of Langerhans; enterovirus; inflammatory mediators; cytokines; nicotinamide; Immunologi;

    Abstract : Type 1 diabetes (T1D) is due to a selective loss of the insulin producing β-cells. However, the process responsible for this loss is still unknown. There is accumulating evidence that enteroviruses (EVs) are involved in T1D. In addition to direct virus-induced cytolysis, EVs could facilitate β-cell destruction by inducing inflammatory cytokines.
