1. 1. Assessment and Treatment of Impaired Insulin- Secretion and Action in Type 2 Diabetes

   Författare :Mozhgan Dorkhan; diabetes och endokrinologi Genomik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 diabetes; insulin secretion; glucagon test; insulin resistance; insulin glargine; insulin tolerance test; thiazolidinediones; natriuretic peptides; adiponectin; thyroid associated ophthalmopathy; proinsulin;

   Sammanfattning : Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. LÄS MER

3. 2. Membrane rafts and its GPI anchored complement inhibitors regulate insulin secretion

   Författare :Vini Nagaraj; Diabetes - öpatofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Membrane rafts; basal insulin secretion; regulated insulin secretion; CD59; CD55; SNARE proteins; insulin; pancreatic beta cells.;

   Sammanfattning : Type 2 diabetic patients usually exhibit an abnormal lipid profile. One such lipid that is constantly elevated in T2D is cholesterol. At the cellular level, cholesterol aids in tight packing of sphingolipids in certain regions of the plasma membrane and these specialized regions are termed ‘membrane rafts’, which act as signalling hubs.

4. 3. Regulation of intracellular signaling events that modulate insulin action

   Författare :Silvia Gogg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; insulin resistance; EGF; Gab 1; insulin receptor substrate; PI3-kinase; ; Thiazolidinediones; PPARã; insulin signaling; glucose transport; adipose tissue; â-cell.;

   Sammanfattning : Insulin regulates several mechanisms of fundamental importance to the body involving glucose, fat andprotein metabolism. Insulin resistance in skeletal muscle, liver and adipose tissue promotes an increaseddemand for insulin secretion. LÄS MER

5. 4. Oscillatory Signaling and Insulin Secretion from Single ß-cells

   Författare :Olof Idevall Hagren; Anders Tengholm; Erik Gylfe; Leslie Satin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP; Ca2 ; oscillations; beta-cell; insulin secretion; evanescent wave microscopy; PIP3; PKA; Epac; Medical cell biology; Medicinsk cellbiologi; Medical Cell Biology; Medicinsk cellbiologi;

   Sammanfattning : cAMP and Ca2+ are key regulators of exocytosis in many cells, including insulin-secreting pancreatic β-cells. Glucose-stimulated insulin secretion from β-cells is pulsatile and driven by oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), but little is known about the kinetics of cAMP signaling and the mechanisms of cAMP action.

7. 5. THE ROLE OF PHOSPHODIESTERASE 3B IN CAMP-MEDIATED REGULATION OF INSULIN SECRETION

   Författare :Helena Jones; Signaltransduktionsforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP; PDE3B; exocytosis; insulin; diabetes; Medicine human and vertebrates ; Medicin människa och djur ; diabetologi; sekretion; Endokrinologi; diabetology; Endocrinology; secreting systems;

   Sammanfattning : Type 2 diabetes mellitus (T2DM) is characterized by various combinations of ?-cell failure and insulin resistance leading to hyperglycemia and glucose intolerance. In order to maintain glucose tolerance in the insulin resistance state, increased insulin secretion is a requirement and it is because of inadequate islet adaptation that glucose intolerance develops in T2DM.
