  2. 11. Pathophysiology and treatment of defective insulin secretion in diabetes

    Author : Anders Rosengren; Diabetes - öpatofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic beta-cells; stem cells; genetics; exocytosis; Adra2a; PACAP; GLP-1; Physiology; Fysiologi; secreting systems; Endocrinology; diabetology; Endokrinologi; insulin secretion; Diabetes mellitus; sekretion; diabetologi;

    Abstract : Defective insulin secretion is a central feature in diabetes mellitus and results from reduced pancreatic beta-cell mass as well as aberrant beta-cell function. The pathophysiology of diabetes is incompletely known, but a strong hereditary component is suggested. READ MORE

  4. 12. Type 2 Diabetes Genes Contributing to Insulin Secretion Defects

    Author : Charlotte Granhall; Genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sekretion; Endokrinologi; exocytosis; GK rat; NIDDM1I; genetics; gene expression; quantitative trait analysis; Sorcs1; Adra2a; Endocrinology; diabetology; insulin secretion; diabetologi; secreting systems; Type 2 diabetes;

    Abstract : Type 2 diabetes is caused by a combination of environmental and inherited factors influencing the progression of insulin resistance and impaired insulin secretion leading to chronically elevated blood glucose levels. The aim of this thesis was to functionally and genetically characterise the species-conserved diabetes locus Niddm1i of the GK rat encoding hyperglycaemia and defect insulin secretion. READ MORE

  5. 13. Ion channel control of phasic insulin secretion

    Author : Xingjun Jing; Diabetes - öpatofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phasic insulin secretion; Diabetes; pancreatic β-cells; ClC chloride channel; exocytosis; CaV channel;

    Abstract : Glucose-stimulated insulin secretion exhibits a biphasic pattern. The mechanism underling biphasic insulin secretion is not fully understood, but consensus exists that an elevation in [Ca2+]i is required for both first- and second-phase insulin secretion. READ MORE

  6. 14. Mechanisms of defective insulin secretion in type 2 diabetes

    Author : Taman Mahdi; Diabetes - öpatofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes; Insulin secretion; TCF7L2; ADRA2A; KCNQ1; SFRP4; interleukin-1B;

    Abstract : Defective insulin secretion from the pancreatic B-cells is a central feature in type 2 diabetes (T2D). There is a strong hereditary component in type T2D, but the underlying pathophysiology remains largely unknown. READ MORE

  7. 15. Oscillatory Signaling and Insulin Secretion from Single ß-cells

    Author : Olof Idevall Hagren; Anders Tengholm; Erik Gylfe; Leslie Satin; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.
