Sammanfattning : ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid.

Sammanfattning : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. LÄS MER
3. Immunoregulatory differences between adult onset type 1 diabetes and latent autoimmune diabetes in adults (LADA)
Sammanfattning : Autoimmune diabetes is characterized by cell mediated autoimmunity against insulin producing beta cells in pancreatic islets. Type 1 diabetes is the major cause of diabetes in children and adolescents and is believed to be mediated by a Thl driven destruction of beta cells. LÄS MER
Sammanfattning : Until recently, the islets of Langerhans were thought to harbour four main cell types characterised with respect to principal hormone product. Here we show that the novel hormone ghrelin is expressed in a fifth islet cell type, the islet ghrelin cell, in humans and rodents. LÄS MER
Sammanfattning : Type 2 diabetes is characterised by defects in insulin sensitivity, insulin secretion and increased endogenous glucose production. The relative contribution of each of these defects remains controversial. LÄS MER
