Serotonin is a chemical nerve cells produce. 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).

The gastric NETs are most likely to derive from ECL cells. 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. In the stomach the EC cells produce 5 HTserotonin while the ECL cells produce from THRS 367 at University of San Diego 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 . The role of EC cell‐derived serotonin in modulating gastrointestinal (GI) motility has been well described .

Vilken effekt har leptin? Vilken effekt har 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.

It is established that hypergastrinaemia can cause ECL cell hyperplasia but it does not affect serotonin cells.
