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. HTR2A-induced basal progenitor proliferation may therefore have contributed to the evolutionary expansion of human neocortex.
Vid aktivering frisätter EC-celler serotonin för att verka på G-celler verkar utsöndrad histamin från ECL-celler på parietala celler för att
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.

A well differentiated neuroendocrine tumor that arises from the colon or rectum and produces serotonin. Colorectal Enterochromaffin Cell Serotonin-Producing Neuroendocrine Tumor MedGen UID: In contrast to the inconsistent overlap between ChgA and peptide hormone expression, ChgA has consistently been associated with enteroendocrine cells producing and secreting monoamines, ie, the histamine producing enterochromaffin (EC)-like (ECL) cells of the stomach and the serotonin-producing EC cells, which constitute a major population of enteroendocrine cells throughout the GI tract (11, 12). We performed RNA-seq analysis of ECL cells. Neither serotonin-secreting nor ECL cells of the corpus arose from cells expressing Neurod1. Serotonin-secreting cells expressed a number of mast cell genes, but not genes associated with endocrine differentiation; they did not develop in c-Kitwsh/wsh mice and were labeled with transplanted bone marrow cells. Serotonin, or 5-hydroxytryptamine, is an amine that is formed from amino acid 5-hydroxytrytophan in the enterochromaffin cells (EC) and in other similar cells called enterochromaffin-like cells (ECL).
Därför påverkar gastrin inte bara utsöndringen av ECL-celler, utan har också en med hyperplastisk anemi är högre än hos patienter utan ECL-cellproliferation. positivt för pro-silverreaktion, och utsöndrad serotonin och substans P. Denna

Differentiation of gastric ECL cells is altered in CCK2 receptor-deficient mice, Anders Abrahamsson, Expression of Serotonin Receptors 2B and 4 in Human.
som ECL-celler spelar de en avgörande roll i mag-tarmregleringen, speciellt i tarmens De producerar mer än 90% av kroppens totala serotonin, liksom en mängd mikrovillier, som gynnar cellulärt svar på fysiska eller kemiska variationer.
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. However, recent findings revealed that impairments in 5-HT synthesis lead to high levels of … 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. Histamine in turn stimulates parietal cells to secrete acid.
Most serotonin-producing enterochromaffin (EC) cell tumors develop in the intestine, with decreasing frequency in the ileum, cecum, appendix, jejunum, duodenum, distal colon, and rectum. Histamine-secreting enterochromaffin-like cells (ECL cells) are prominent among the endocrine cells of the human gastric oxyntic mucosa. In sporadic cases they can give rise to tumors sometimes unrelated to hypergastrinemia.
