In sporadic cases they can give rise to tumors sometimes unrelated to hypergastrinemia. Results to date indicate that ECL cells from rats secrete histamine in response to stimulation by gastrin (CCK-2 receptor subtype) and PACAP (PAC1 receptor subtype), but not by acetylcholine. PYY and the neurotransmitter galanin inhibit ECL cell histamine release by binding to PYY type 1 and galanin type 1 receptors, respectively. 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.

De indelas i 3 undergrupper: ECLom typ 1: Utvecklas vanligen hos patienter med kronisk atrofisk gastrit. Den patofysiologiska bakgrunden är stigande gastrinnivåer som svar på utebliven syrasekretion i ventrikeln. 2. Which cell organelles are well-developed in secretory cells? In secretory cells, such as the secretory cells of endocrine glands, organelles related to the production, processing and “export” of substances are widely present and well-developed. These organelles are the rough endoplasmic reticulum and the Golgi apparatus.

These cells are stimulated by the hormones gastrin (not depicted in the adjacent diagram) and pituitary adenylyl cyclase-activating peptide . G cells are stimulated by vagal stimulation through the neurotransmitter gastrin-releasing peptide ; this causes the G cells to secrete gastrin, which in turn stimulates ECL cells to release histamine.

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. Histamine in the stomach occurs in endocrine cells (so-called enterochromaffin-like (ECL) cells), mast cells, and neurons. The ECL cells are peptide hormone-producing cells.

The labeling of ECL cells was only modestly reduced by cycloheximide, an inhib- itor of protein synthesis, whereas the labeling of A- like and other endocrine cells was almost abolished. In contrast, the labeling of ECL cells was markedly Received December 15,1978.

The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast cells. We studied the consequences of depleting ECL-cell histamine by continuous infusion of the HDC inhibitor a-fluoromethylhistidine 2003-08-05 VPAC. PACAP elevated [Ca2+]i in ECL and parietal cells of superfused gastric glands, but only the parietal cell signal was inhibited by ranitidine, showing the absence of PAC1 on parietal cells, and demonstrating functional coupling between the cell types.

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).

“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.

… Those characteristics did not depend on cell thickness of the ECL cell. … NAID 110009624242; 交流駆動型電気化学発光素子の試作と基本的な電気的特性 Cells are the basic building materials for all living things. But much of the lives of cells are still unknown and unexplored. More knowledge about cells wil crine cells only lightly.
