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.

ECL cells in the oxyntic mucosa control gastric acid secretion (Ha˚kanson & Sundler, 1991; Waldum et al., 1991; Andersson et al., 1996). They respond to gastrin with the release of histamine, flooding adjacent parietal cells. While the existence of a gastrin-ECL cell-parietal cell axis seems widely accepted

ECL cells synthesize and secrete histaminein response to stimulation by the hormones gastrinand pituitary adenylyl cyclase-activating peptide. gastric ECL cell density, and it has been suggested that the metabolite excretion rate can serve as a possible marker of advanced ECL cell changes.20–22 Similarly, the magnitude of the serum CgA level has been shown to reflect the number of gastric ECL cells in some studies.16, 17, 23, 24 Many patients with Zollinger–Ellison syndrome cannot In human digestive system: Serotonin …amino acid 5-hydroxytrytophan in the enterochromaffin cells (EC) and in other similar cells called enterochromaffin-like cells (ECL). These cells also secrete histamine and kinins, which likewise have important messenger functions in glandular secretions and on blood vessels. Enterochromaffin cells are enteroendocrine and neuroendocrine cells with a close similarity to adrenomedullary chromaffin cells secreting serotonin. Enterochromaffin-like cell.

Dependent on concentration, serotonin can then modulate peristaltic contraction and secretion through activation of smooth muscle and glands, respectively. Pulmonary neuroendocrine cells in the respiratory tract are known as bronchial Kulchitsky cells. En annan typ av krombindande celler finns bara i magsäcksväggen och kallas enterokromaffin-liknande celler (ECL). De ser ut som EC-celler, men innehåller inte serotonin. ECL-celler svarar på gastrin från G-celler och de frisätter histamin vilket stimulerar parietalcellerna att producera magsaft.

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.

Serotonin is found mostly in the digestive system, although it’s also in blood platelets gastric ECL cell density, and it has been suggested that the metabolite excretion rate can serve as a possible marker of advanced ECL cell changes.20–22 Similarly, the magnitude of the serum CgA level has been shown to reflect the number of gastric ECL cells in some studies.16, 17, 23, 24 Many patients with Zollinger–Ellison syndrome cannot Histamine-expressing ECL cells, while lacking NeuroD, did not appear to express granulocyte or mast cell markers by analytical flow cytometry and RT-PCR, and resemble other enteroendocrine cell populations. Mouse gastric corpus serotonin cells, but not antral serotonin cells, are bone marrow-derived mast cells.
