  1. 1. Signal Transduction of Glucagon Secretion

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elaine Vieira; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; secretion; glucagon; store-operated channels; calcium; diabetes; Cellbiologi; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Abstract : Diabetes mellitus is a bihormonal disorder with hyperglycemia due to deficiency of insulin and hypersecretion of glucagon. To improve diabetes treatment it is important to clarify the signal transduction of glucagon secretion. READ MORE

  2. 2. Impaired Glucose Tolerance in Childhood Obesity Contribution of Glucagon, GLP-1 and Inflammation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hannes Manell; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood obesity; impaired glucose tolerance; type 2 diabetes; glucagon; glucagon-like peptide-1; dipeptidyl peptidase-4; inflammation; free fatty acids; insulin; visceral adiposity; Medicinsk vetenskap; Medical Science;

    Abstract : In the wake of increased obesity prevalence, impaired glucose tolerance (IGT) and type 2 diabetes (T2D) in childhood and adolescence is increasingly common. Given the negative impacts these conditions have on health over time, understanding the pathophysiology in those affected early in life is important. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Qian Yu; Uppsala universitet.; [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.

    Abstract : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. READ MORE

  5. 5. Novel insights into the regulation of insulin secretion by GLP-1, GIP and glucagon

    University dissertation from Medicine (Lund)

    Author : Linda Ahlkvist; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vagus nerve; GPR119; Insulin resistance; Glucagon; GIP; GLP-1; Insulin;

    Abstract : Popular Abstract in Swedish När vi äter socker frisätter kroppen hormonet insulin från specifika beta-celler i bukspottskörteln för att förmå muskelceller och fettceller att ta upp sockret från blodet och därmed återställa blodets sockerbalans. Vid övervikt blir dessa vävnader resistenta mot insulinets verkan vilket leder till att sockret stannar kvar i blodet. READ MORE
