No peptide product has been identified as yet in human ECL cells, although those of rodents are known to secrete histamine, which can be demonstrated using specific antibodies or antibodies against the enzyme histidine decarboxylase. Under the electron microscope, ECL …
Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise.. Originating from the histamine-containing enterochromaffin-like (ECL) cells of the embryologic foregut, gastric carcinoid tumors represent
(B)Secretin stimulates the pancreatic acinar cells to secrete enzymes. except: ( A)It is GIT hormone secreted by the duodenal mucosa in response to presence Stomach cells secrete and muscle cells contract; Pancreas, gallbladder releases bile which enters the blood stream and activates parietal cells and ECL cells. Chief cells produce pepsinogen, trypsin is released from the pancreas into the small intestine, and ECL cells release histamine to stimulate parietal cells to secrete the chief cells secrete what, pepsinogen. the parietal cells secrete what, hydrochloric acid and Intrinsic factor. the ECL cells secrete what, histamine. the G cells Of the three agonists that normally would cause the gastric cells to secrete acid, Gastrin binds to the receptors CCKB on ECL cells, cause ECL cells to release av M Björkqvist · 2002 — In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. The first aim of the study was to prepare isolated ECL cells T1 - Somatostatin, misoprostol and galanin inhibit gastrin- and PACAP-stimulated secretion of histamine and pancreastatin from ECL cells by blocking specific Ca( Abstract : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach.
Gastrin itself is secreted by cells in the epithelium of the stomach, but travels to ECL cells via the blood. Gastric acid secretion is under nervous and hormonal control. Gastrin, the major circulating stimulus of acid secretion, probably does not stimulate the parietal cells directly but acts to mobilize histamine from the ECL cells in the oxyntic mucosa. Histamine stimulates the parietal cells to secrete HCl. No peptide product has been identified as yet in human ECL cells, although those of rodents are known to secrete histamine, which can be demonstrated using specific antibodies or antibodies against the enzyme histidine decarboxylase. Under the electron microscope, ECL cells are easily distinguishable from EC cells. Other articles where Enterochromaffin cell is discussed: 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.

Enteroendocrine cells are the hormone secreting cells present in the glands or mucosa of the gastrointestinal tract, particularly the stomach and intestine. The enteroendocrine cells present in gastric glands are G cells, EC cells, and ECL cells. FUNCTIONS OF GASTRIC GLANDS The function of the gastric gland is to secrete gastric juice. Start studying The stomach, acid secretion and ulcers.
The enterochromaffin-like (ECL) cells of the oxyntic mucosa (fundus) of the stomach produce, store and secrete histamine, chromogranin A-derived peptides such as pancreastatin, and an unanticipated but as yet unidentified peptide hormone. The cells are stimulated by gastrin and pituitary adenylate cyclase activating peptide and suppressed by somatostatin and galanin.

Prior to the recognition of the ECL cell as the pivotal regulator of gastric acid secretion, there was considerable confusion in regard to the mechanism by which the parietal cell was stimulated to secrete acid. The identification of the ECL cell and the recognition of its primary secretory product, histamine, dispelled the previous notion that
2020-06-09 · Definition. Goblet cells are a specialized type of epithelial cell that secrete mucins, which are significant components of mucus. They are most often found in the respiratory and gastrointestinal tracts, where they make up part of the surface epithelium. 類腸嗜鉻細胞（ Enterochromaffin-like cells ），常簡稱ECL細胞（ ECL cells ）是一種胃黏膜上的神經分泌細胞，常分布於胃壁細胞附近。ECL細胞能分泌組織胺，輔助胃酸的分泌。這種細胞被認為屬於一種 腸道內分泌細胞 （ 英語 ： enteroendocrine cells ） 。 參見
ECL cells are histamine‐containing endocrine/paracrine cells in the oxyntic mucosa of the stomach. They play a key role in the control of acid secretion because of their ability to secrete histamine, which stimulates adjacent acid‐producing cells (for reviews see Håkanson et al. 1994, 1998).

Answer: Enhances satiety, stimulates gallbladder contraction and pancreatic enzyme secretion, and inhibits gastric emptying and acid secretion. See Table 21.1 in the chapter. Enterochromaffin-like (ECL) cells produce histamine, which is important in the release of stomach acid. They are typically found in the base of the gastric glands. G-cells secrete the peptide hormone gastrin into the blood stream.

Stomach Structure– Enterochromaffin-like (ECL) cells secrete histamine Gastrin: made in G cells; carried to parietal cellsin blood– Also stimulates ECL cells to
In response to chemical and mechanical stimuli, these cells secrete a variety of important hormones, such as GLP-1 and GLP-2, PYY, CCK, and serotonin.

The histamine is released from the vesicles situated within the gastric mucosal cells. Histamine then stimulates the ECL cells to secrete hydrochloric acids. Enteroendocrine cells are the hormone secreting cells present in the glands or mucosa of the gastrointestinal tract, particularly the stomach and intestine.
