Det enda jag hittat i form av forskning kring att höja serotonin med kost I magsäckens slemhinna finns s.k. ECL-celler som frisätter histamin

Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. What Is Serotonin? 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.

Tumörerna utgår från de så kallade ECL-cellerna (enterochromaffin like cells). Vid aktivering frisätter EC-celler serotonin för att verka på G-celler verkar utsöndrad histamin från ECL-celler på parietala celler för att (ECL, EC, G) vesikulär monoamintransportör typ 2 (VMAT2) serotonin gastrin skall ECL-cell proliferationer >0,5 mm klassas som neuroendokrina tumörer D-cells → Somatostatin L-celler → GLP-1.

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

Serotonin, a neurotransmitter with numerous functions in the central nervous system (CNS), is emerging as an important signaling molecule in biological processes outside of the CNS. Recent advances have implicated serotonin as a regulator of inflammation, proliferation, regeneration, and repair. The role of serotonin in tumor biology in vivo has not been elucidated. Using a genetic model of Xing et al. uncover a novel role of the serotonin receptor HTR2A distinct from its function in neurotransmission, and that role is to increase basal progenitor proliferation in the embryonic ferret and fetal human neocortex.

Serotonin-expressing cells of the gastric corpus of mice appear to be bone marrow-derived mucosal mast cells. Gene expression analysis of ECL cells indicated that they are endocrine cells of epithelial origin that do not express the same transcription factors as their intestinal enteroendocrine cell …

Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. In the present study we assessed the usefulness and 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. 2016-12-29 In this issue of Blood, León-Ponte and colleagues not only consolidate serotonin's importance to T-cell activation but also tender a paradigm whereby the monoamine is provided by the immune cell itself.Critical to any outcome from 5-HT exposure—whether the source be autocrine or paracrine—is a capacity for target cells to sense the monoamine. Oxidative stress plays an important role in the pathogenesis of liver diseases. N-Acetyl-serotonin (NAS) has been reported to protect against oxidative damage, though the mechanisms by which NAS protects hepatocytes from oxidative stress remain unknown.

Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. There are different neuroendocrine cells in the stomach: G cells (antrum), D cells (corpus and antrum), EC-like (ECL) cells (corpus and fundus), D1 cells, EC cells, parietal cells, and X cells, which have different products and are prone to tumor formation. The gastric NETs are most likely to derive from ECL cells.

These cells also secrete histamine and kinins, which likewise have important messenger functions in glandular secretions and on blood vessels. Enterochromaffin cells are enteroendocrine and neuroendocrine cells with a close similarity to adrenomedullary chromaffin cells secreting serotonin. Enterochromaffin-like cell. Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell secreting histamine.

Serotonin exerts many actions and, like histamine, displays many species differences, making generalizations difficult. The actions of serotonin are mediated through a remarkably large number of cell membrane receptors. The serotonin receptors that have been char-acterized thus far are listed in Table 16–3.
