  2. Gastrin - Wikipedia

    en.wikipedia.org/wiki/Gastrin

    Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach.It is secreted into the bloodstream. The encoded polypeptide is preprogastrin, which is cleaved by enzymes in posttranslational modification to produce progastrin (an intermediate, inactive precursor) and then gastrin in various forms, primarily the following three:

  3. Gastrointestinal hormone - Wikipedia

    Little gastrin: 2098: 17: Both forms of gastrin are found in the gastric antrum and duodenum: Gastrins stimulate the secretion of gastric acid, pepsinogen, intrinsic factor, and secretin; stimulate intestinal mucosal growth; increase gastric and intestinal motility Big gastrin: 3839: 34: Secretin-glucagon family: Secretin: 3056: 27: Duodenum ...

  5. G cell - Wikipedia

    en.wikipedia.org/wiki/G_cell

    A G cell or gastrin cell is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas [1] and duodenum. The vagus nerve innervates the G cells.

  6. Enterochromaffin-like cell - Wikipedia

    en.wikipedia.org/wiki/Enterochromaffin-like_cell

    Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells, that aid in the production of gastric acid via the release of histamine. They are also considered a type of enteroendocrine cell. [1]

  7. Progastrin - Wikipedia

    en.wikipedia.org/wiki/Progastrin

    Progastrin is an 80-amino acid intracellular protein and the precursor of gastrin, a gastrointestinal hormone produced by G cells in the gastric antrum. [1] The main function of gastrin is to regulate acid secretion. [2] During digestion, only gastrin is released into the bloodstream and stimulates the secretion of hydrochloric acid in the ...

  8. Enterogastric reflex - Wikipedia

    en.wikipedia.org/wiki/Enterogastric_reflex

    It can also be stimulated by a pH of 3-4 in the duodenum and by a pH of 1.5 in the stomach. Upon initiation of the reflex, the release of gastrin by G-cells in the antrum of the stomach is shut off. This in turn inhibits gastric motility and the secretion of gastric acid . [1]

  9. Pro-gastrin-releasing-peptide - Wikipedia

    en.wikipedia.org/wiki/Pro-Gastrin-Releasing-Peptide

    Pro-gastrin-releasing-peptide, also known as Pro-GRP, is a gastrin-releasing peptide (GRP) precursor, a neurotransmitter that belongs to the bombesin-related neuromedin B family. GRP stimulates the secretion of gastrin in order to increase the acidity of the gastric acid .
