2018-03-19 · EC Serotonin-Producing NET of Pancreas is very rare and generally affects middle-aged adults. From available data, it appears that the tumor predominantly appears in the head region of the pancreas, although the body and tail regions may be affected as well.

Carcinoid, predominantly enterochromaffin cell, serotonin producing Rectum and distal colon Carcinoid, predominantly L cell, glucagon-like peptide and pancreatic peptide (PP) producing

Histaminet stimulerar till Avhandlingar om ENTEROCHROMAFFIN CELL. originate from serotonin-producing enterochromaffin (EC) cells in the intestinal mucosa. stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. Typ 2: ECL-cells-NET associerad med MEN1 och Zollinger-Ellisons syndrom .

These results imply that serotonin secreted from the apical ganglion into the blastocoel stimulates the elevation of [Ca2+]i in the larval ectodermal cells through the serotonin receptor cell network. ECL-cell (fysiologi) enskild cell av en typ av celler som finns i magsäckens slemhinna och producerar histamin som en del i regleringen av saltsyrasekretionen G-cellerna producerar gastrin som får ECL-cellerna att frisätta histamin, som i sin tur får parietalcellerna att producera saltsyra. 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. To determine whether pretreatment with NAS could reduce hydrogen peroxide- (H₂O₂-) induced oxidative stress in HepG2 Serotonin/5-hydroxytryptamine (5-HT), often perceived as the brain's “happy chemical,” is—increasingly—assuming a prominent role in immune regulation.

En annan typ av krombindande celler finns bara i magsäcksväggen och kallas enterokromaffin-liknande celler (ECL). 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 producera magsaft.

G and ECL endocrine cells were decreased in stomach of alcoholic subjects and total enteroendocrine cell count in the rat gastric and duodenal mucosa was. It is established that hypergastrinaemia can cause ECL cell hyperplasia but it does not affect serotonin cells.

The enterochromaffin-like (ECL) cell carcinoids of the body and fundic area of the stomach often seen in association with pernicious anaemia are argyrophil with the Sevier-Munger silver stain. 2016-09-01 ECL-cell histamine mobilization in conscious rats: e•ects of locally applied regulatory peptides, candidate neurotransmitters and Also acetylcholine, carbachol, serotonin and the amino acid neurotransmitters aspartate, g-aminobutyric acid, glutamate and glycine were inactive or weakly active as was bradykinin. Chromogranin A expression is used for ECL cell quantitation by subtracting somatostatin- and serotonin-producing cells from the total number of labelled cells to obtain an ECL cell count 14. Kakehasi 14 reported that ECL cells appear to constitute 30-40% of the cells in the oxyntic mucosa when identified using chromogranin A. Serotonin (5-HT) has complex effects on the central nervous system (CNS), neuroendocrine mechanisms, immunological reactions, intestinal microbiome, and cancer. It has been associated with more severe signs and symptoms of colitis, as well as promoting colorectal cancer (CRC) cells toward expansion.

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-cell tumors similar to those in the colon.

Gastrin-producing tumour (with or without function), somatostatin-, or serotonin-producing tumours endogenous toxins and poisons ) --- release mucosal serotonin from entero- chromaffin like cells (ECL cells) which activate 5HT3 receptors.
