  1. 1. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    Abstract : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. READ MORE

  2. 2. α-Cell signalling in glucose-regulated glucagon secretion

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Qian Yu; Anders Tengholm; Erik Gylfe; Sebastian Barg; David W Piston; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islets; glucagon; insulin; somatostatin; ATP; cAMP; Ca2 ; GHB; oscillations; α-cell; β-cell; δ-cell; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Glucagon is a blood glucose-elevating hormone released from α-cells in the islets of Langerhans during hypoglycaemia. Glucagon is critical for glucose homeostasis and inappropriate regulation of its secretion underlies both impaired counter-regulation of hypoglycaemia and chronic hyperglycaemia in diabetes patients.

  3. 3. Cell coupling and exocytosis measured in intact mouse pancreatic islets Control of {delta}-cell secretion

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Quan Zhang; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Patch-clamp and capacitance measurements were applied to α-, β- and δ-cells in intact mouse pancreatic islets. The maximum rate of β-cell exocytosis during a depolarization to 0 mV was 14 granules/s, ... READ MORE
