1 Gastrin stimulates rat stomach ECL cells to secrete histamine and pacreastatin, a chromogranin A (CGA)-derived peptide. The present report describes the e•ect of nine cholecystokinin2 (CCK2) receptor antagonists and one CCK1 receptor antagonist on the gastrin-evoked secretion of pancreastatin from isolated ECL cells. Anaesthetic agents inhibit gastrin-stimulated but not basal histamine release from rat stomach ECL cells 1P. Norle´n, 1M.

Proteins participating in vesicular docking and fusion have been identified in the nervous system. Such proteins appear to be important for the molecular regulation of exocytosis also in non-neuronal cells. The enterochromaffin-like (ECL) cells of the gastric acid-secreting (oxyntic) mucosa secrete histamine and chromogranin A-derived peptides, such as pancreastatin.
The distribution of both ECL and mast cells varies with the species. ECL cell variant (Enterochromaffin-like cell neuroendocrine tumors) Tropic effect from gastrin, related to long standing elevated gastrin levels from gastrinoma or gastric gastrin cells responding to achlorhydria. Usually associated with ECL cell hyperplasia and may be difficult to distinguish from hyperplasia. Distributed throughout whole stomach. Enterochromaffin (EC) cells: produce serotonin Distributed throughout whole stomach. Enterochromaffin-like (ECL) cells: produce histamine (Int J Mol Sci 2019;20:E2444) Limited to the gastric body and fundus Secrete histamine in response to gastrin produced by G cells Represent 30% of all endocrine cells
Ageing cells, especially post-mitotic cells, are known to accumulate pigments, i.e. highly electron-dense material, referred to as ceroid or lipofuscin.
Refeeding of fasted rats or treatment with the The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid. Do they also operate under nervous Many of the endocrine cells in the stomach are poorly characterized with respect to physiological significance.

The cells respond to gastrin via cholecystokinin-2 (CCK2) receptors. A CCK2 receptor blockade was induced by treatment (for up to 8 weeks) with two receptor antagonists, YM022 and YF476. Changes in ECL-cell morphology were examined by immunocytochemistry and … in the stomach: the oxyntic mucosa and the antral mucosa. Parietal cells, which make up some 80% of the acid-secreting gastric mucosa, are located in the oxyntic mucosa. They are found proximally in the gastric body and fundus, intermingled with histamine-secreting enterochromaffin-like cells (ECL) and the main pepsinogen-secreting cells.
