  1. 16. Regulation of docking and priming in pancreatic α- and β-cells

    Author : Muhmmad Omar-Hmeadi; Sebastian Barg; Patrick MacDonald; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type-2 diabetes; glucagon; insulin; somatostatin; exocytosis;

    Abstract : The secretion of islet hormones from endocrine cells of the pancreas plays vital roles in maintaining glucose homeostasis. Dysfunction of these cells leads to diabetes, a devastating metabolic disorder affecting millions worldwide, but underlying mechanisms remain poorly understood. READ MORE

  2. 17. Characterization of Impaired Glucose Tolerance - Insulin Sensitivity, Islet Function and Metabolic Risk Factors

    Author : Hillevi Larsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; muscle fiber type; androgen activity; proinsulin; glucagon; insulin secretion; insulin sensitivity; Impaired glucose tolerance; type 2 diabetes; sekretion; diabetologi; Endokrinologi; diabetology; secreting systems;

    Abstract : This thesis presents a three-year prospective study on metabolic characteristics of impaired glucose tolerance (IGT) and the regulation of insulin sensitivity versus islet function in relation to changes in glucose tolerance. 108 non-diabetic women aged 57-58 years were randomly selected from a population of women born in 1935 with a high prevalence of IGT.

  3. 18. The role of CART in islet function

    Author : Mia Abels; Neuroendokrin cellbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cocaine- and amphetamine-regulated transcript; CART; Diabetes; T2D; Human islets; Glucagon; Insulin; Adipocyte;

    Abstract : Diminished insulin secretion and dysregulated glucagon secretion are key features of type 2 diabetes (T2D). The overall aim of this thesis was to study the role of cocaine- and amphetamine-regulated transcript (CART) in islet cell function and how CART regulates glucose homeostasis. READ MORE

  4. 19. Regulation of Islet Function by the Neuropeptide PACAP

    Author : Karin Filipsson; Diabetes - molekylär metabolism; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postprandial; calcium; sodium; cAMP; intracellular signaling; glucagon; insulin; Pituitary adenylate cyclase-activating polypeptide; PACAP receptors; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : It is known that parasympathetic, sympathetic and sensory nerves innervate the islets and that these nerves harbor both classical neurotransmitters and neuropeptides. However, the neural influence on islet hormone release is complex and not yet fully understood A recently discovered pancreatic neuropeptide is pituitary adenylate cyclase-activating polypeptide (PACAP).

  5. 20. Origin, release and functional significance of the novel gastric hormone ghrelin

    Author : Charlotta Dornonville de la Cour; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxicology; Farmakologi; pharmacognosy; pharmacy; Pharmacological sciences; bone metabolism; energy homeostasis; glucagon; insulin; secretion; pancreastatin; somatostatin; histamine; gastrin; gastric acid secretion; ghrelin; gastric motility; A-like cells; farmakognosi; farmaci; toxikologi;

    Abstract : The novel gastric hormone ghrelin was discovered by virtue of its ability to release growth hormone (GH) via interaction with the so-called GH-secretagogue receptor (GHS-R). Earlier only synthetic agents were known to bind with the GHS-R, hence, ghrelin is the first identified endogenous ligand. READ MORE
