Gastrin is produced in antral G cells; histamine is found in mast cells, ECL responding to antigenic challenges with histamine and serotonin release (5, 6).

Our journals promote pharmacology in all its forms by disseminating the latest high quality research in our peer reviewed scientific journals. Serotonin transporters located on the platelet membrane and enterochromaffin cells are responsible for uptake into those cells. Serotonin that escapes uptake and liver metabolism reaches the lung where is it then metabolized (Tyce, 1990). THE 5-HT RECEPTOR FAMILIES The diverse effects of serotonin are mediated via 5-HT receptors. 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 EC cells function as luminal sensors, and increasing pressure in the colonic lumen leads to a change in the level of endogenous, luminal 5‐HT .

Serotonin (also known as 5-hydroxytryptamine or 5-HT) is a naturally occurring substance that functions as a neurotransmitter to carry signals between nerve cells (called neurons) throughout your body. Se hela listan på frontiersin.org ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. ECL-Zellen sind neuroendokrine Zellen der Magenschleimhaut, die Histamin ausschütten und dadurch die Magensäureproduktion der Parietalzellen des Magens anregen. Sie gehören zum enterischen endokrinen System und sind damit Teil des diffusen neuroendokrinen System (DNES). 2 Nomenklatur Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat.

It sends signals between your nerve cells. 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. Furthermore, the so-called 窶徘eripheral serotonin,窶・which is almost entirely derived from the EC cells, has been shown also to control the functions of brown adipose tissue (16窶・span class="xrefLink" id="jumplink-B18">18). Carcinoid, predominantly enterochromaffin cell, serotonin producing Rectum and distal colon Carcinoid, predominantly L cell, glucagon-like peptide and pancreatic peptide (PP) producing Preparations of these cells were used for both in vitro serotonin release experiments and transcriptional profiling. The presence of cell contamination with other NE cells (47), as well as the high chemical doses (10 5–10 4 M) required to elicit seroto-nin release in these cells (46), suggests the need to develop homogenous ileal EC cell creting enteroendocrine cells and harbor histamine-secret-ing enterochromaffin-like (ECL) cells, somatostatin-secret-ing D cells, and a few serotonin-secreting enterochromaffin (EC) cells (77, 239) (FIGURE 1). In contrast, the antral or pyloric glands contain foveolar surface mucous cells and Muc6-expressing deep mucous cells.
