Results: The ECL cell carries the gastrin receptor, and gastrin regulates its function (histamine release) as well as proliferation. Long-term hypergastrinemia results in gastric neoplasia of variable malignancies, implying that gastric hypoacidity resulting in increased gastrin release will induce gastric neoplasia, including gastric cancer. HISTAMINE SECRETION FROM ECL CELLS Histamine secretion from ECL cells is of critical importance for gastric acid secretion. In vivo studies have shown that the antral hormone gastrin is the main stimulus for acid secretion and histamine release.

“Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine. In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. What do chief cells secrete? ECL-cell histamine plays an important role in the regulation of gastric acid secretion, particularly in response to gastrin stimulation. The time-course responses of ECL cells to gastrin include Unlike mast cells and basophils, ECL cells and histaminergic neurons do not store histamine. Instead, the production and release of histamine in these cells depend on physiologic stimuli. In the gut, for example, histidine decarboxylase is activated after the ingestion of food.

The ECL cells are peptide hormone-producing cells.

This causes inflammation, which lets Oct 9, 2020 Histamine stimulates the parietal cells to secrete HCl. The gastrin-ECL cell pathway has been investigated extensively in situ (gastric Therefore, the main histamine source is the human body. Histamine is made from histidine, it is stored in mast cells (immune system cells) and basophils Mar 23, 2018 Here, we presented the methods to detect human islet autoantibodies using electrochemiluminescence (ECL) assays.

Enterochromaffin-like (ECL) cells are neuroendocrine cells in the gastric mucosa that control acid secretion by releasing histamine as a paracrine stimulant. The antral hormone gastrin and the neural messenger pituitary adenylyl cyclase–activating peptide (PACAP) potently stimulate histamine synthesis, storage, and secretion by ECL cells.

In response to gastrin released by neighbouring G-cells, secreted histamine from ECL cells acts on parietal cells to stimulate the release of gastric acid. Abstract ▪ Abstract Enterochromaffin-like (ECL) cells are neuroendocrine cells in the gastric mucosa that control acid secretion by releasing histamine as a paracrine stimulant. (38). Histamine from the ECL cells being mainly located at the base of the glands (7), may reach the parietal cell not only by the paracrine route but also via the capillaries ( 18). Thus, the ECL cell via histamine release plays a central role in the regulation of gastric acid secretion (Figure). The ECL cell may also produce other mediators. “Enterochromaffin-like (ECL) cells” are a population of cells that are found in the gastric pits of the stomach luminal epithelium and secrete histamine.

3). The ECL-cell histamine mobilization was independent of the concentrations of Ca2+ in the perfusion medium (0-3.4 mmol/l Ca2+).
