High levels of serotonin can be released by the tumors when they are manipulated such as during surgery, hepatic artery embolization, palpation of the live during a routine abdominal exam to measure an enlarged liver. Strong emotions and stress can also stimulate these tumor cells to produce and release exaggerated levels of serotonin.

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).

De ser ut som EC-celler, men innehåller inte serotonin. ECL-celler svarar på gastrin från G-celler och de frisätter histamin vilket stimulerar parietalcellerna att  Histamin förmedlar sina cellfysiologiska verkningar via fyra G- affinitet men med hög kapacitet) andra monoaminer, såsom serotonin och dopamin.

Serotonin/5-hydroxytryptamine (5-HT), often perceived as the brain's “happy chemical,” is—increasingly—assuming a prominent role in immune regulation. In fact, this “neurotransmitter” is primarily a product of the periphery, with gut enterochromaffin cells the principal factories.

Most appendiceal carcinoids are serotonin-producing EC-cell tumors similar to carcinoids that occur in the jejunum and ileum; less commonly, appendiceal carcinoids are L … Instead, the ECL cells operate under long-term tonic control by the vagus, and vagal denervation of the stomach leads to ECL-cell gastrin receptor desensitization.

Maruyama et al. provide evidence from mouse experiments that fecal single-stranded RNA (ssRNA) is sensed in the gut by the cation channel Piezo1. They show that ssRNA-stimulated Piezo1 is involved in peristalsis and gut serotonin synthesis and reduced bone mass. The ssRNA-Piezo1 axis reported could be a prophylactic target for treatment of bone and gut disorders, including the side effects of Serotonin binds the serotonin receptor Htr1b found on the cell surface of osteoblasts, leading to decreased CREB phosphorylation and eventually downregulation of osteoblast proliferation. 10 Moreover, pharmacologic inhibition of Tph1 in mice decreases GDS levels and increases bone mass, indicating a pivotal role of serotonin as a molecular brake of osteoblastogenesis/new bone formation. 18 Assay Genie ECL Western Blotting Substrate is a highly sensitive, nonradioactive, enhanced luminol-based chemiluminescent substrate for easy detection of horseradish peroxidase (HRP) on immunoblots.
