  1. 11. A molecular approach to insulin signalling and caveolae in primary adipocytes

    Författare :Karin Stenkula; Fredrik Nyström; Peter Strålfors; Peter Arner; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caveolae; insulin signalling; adipocytes; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : The prevalence of type II diabetes is increasing at an alarming rate due to the western world lifestyle. Type II diabetes is characterized by an insulin resistance distinguished by impaired glucose uptake in adipose and muscle tissues. LÄS MER

  3. 12. Caveolae structure and importance in insulin action

    Författare :Hans Thorn; Johan Thyberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Type II diabetes is a disease characterized by chronic hyperglycaemia and abnormalities in lipid metabolism that affects approximately 5% of the population in the Western World. Caveolae are invaginations of the plasma membrane, described as 25-150 nm omega shaped structures, which are enriched in cholesterol, sphingolipids and the constituent protein caveolin. LÄS MER

  4. 13. Cyclic AMP Oscillations in Insulin-Secreting Cells

    Författare :Jenny Sågetorp; Anders Tengholm; Erik Gylfe; Lena Stenson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : Cyclic AMP is an intracellular messenger that regulates numerous processes in various types of cells. In pancreatic β-cells, cAMP potentiates the secretion of insulin by promoting Ca2+ signals and by amplifying Ca2+-triggered exocytosis. Whereas Ca2+ signals have been extensively characterized, little is known about the kinetics of cAMP signals. LÄS MER

  5. 14. Interleukin-6 as a mediator of insulin resistance

    Författare :Victoria Rotter Sopasakis; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : A potential role of interleukin (IL)-6 for the metabolic abnormalities seen in obesity and insulinresistance was postulated when it was discovered that circulating IL-6 levels were elevated in obeseand insulin-resistant as well as type 2 diabetic individuals. Later it was shown that the adipose tissuewas a major site of IL-6 production, accounting for 15-35% of the total circulating levels. LÄS MER

  7. 15. Mechanisms of insulin signaling and the role of caveolae

    Författare :Santiago Parpal; Pam Fredman; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Insulin regulates metabolic as well as mitogenic processes in target cells, involving a large number of mediators of signal transduction. In its role as a growth factor, insulin stimulates cell growth, in a process we demonstrate requires the participation of the Raf-1 kinase. LÄS MER
