ECL cells

Enterochromaffin-like or ECL cells are a distinctive type of neuroendocrine cell in the gastric mucosa underlying the epithelium. They are most prevalent in the acid-secreting regions of the stomach. ECL cells synthesize and secrete histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide ECL cells histologically appear similar to EC cells and are hence named as such. They are however a different cell type and do not possess any serotonin synthesizing mechanisms. [citation needed] Development. In developing chick embryos, EC cells have been found in biopsies of developing GIT tissue before the migration of neural crest cells Enterochromaffin-like (ECL) cells, in contrast to EC cells, are confined to a single region of the gut, the gastric fundus, where they form the major endocrine cell population. ECL cells have no lumenal connection ( Fig. 6 ). The cells are argyrophil but nonargentaffin

Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise ECL cells synthesize and secrete histamine in response to stimulation by the hormones gastrin and pituitary adenylyl cyclase-activating peptide. Gastrin itself is secreted by cells in the epithelium of the stomach, but travels to ECL cells via the blood ECL cells load with Fluo-4 dyes to a greater extent than do parietal cells, presumably due to accumulation of the dye in secretory vacuoles. ECL cells in the rabbit gastric glands used in this study can be identified by this loading characteristic, their size, number, location, and the accumulation of acridine orange in their secretory vacuoles ECL Cell Attachment Matrix.

Enterochromaffin-like (ECL) cells: produce histamine (Int J Mol Sci 2019;20:E2444) Limited to the gastric body and fundus Secrete histamine in response to gastrin produced by G cells Represent 30% of all endocrine cells Long term gastrin stimulation causes enterochromaffin-like cell hyperplasia (e.g. in atrophic gastritis Unlike parietal cells, ECL cells are capable of proliferation and are stimulated to do so by gastrin. The absence of gastrin in the gastrin KO mouse is associated with reduced parietal cell mass, inactivation of ECL cells and subsequent reduction of actively secreting parietal cells ECL cell carcinoid — enterochromaffin like cell carcinoid a small, circumscribed, often polypoid tumor of the gastric fundus, consisting of enterochromaffin like (ECL) cells and believed to be secondary to hypergastrinemia, which stimulates the proliferation of ECL.

Prepare ECL mix (following the proportion of solution A and B provided by the manufacturer). Incubate the membrane for 1-2 minutes [Figure 10]. (Tip: Use a 1000 μL pipette to ensure that ECL covers the top and bottom of the membrane) enterochromaffin-like (ECL) cells are endocrine cells of the gastric mucosa, constituting ∼1-3% of the fundic epithelial cell volume. ECL cells display typical features of neuroendocrine cells and can be detected by staining with bivalent cations using the Grimelius staining protocol ( 52 , 94 ) The ECL cells are the predominant endocrine cell population in the oxyntic mucosa. They produce histamine, chromogranin A/pancreastatin and an as yet unidentified peptide hormone. They respond to gastrin by the release of secretory products; more long-term responses include adaptation to the gastrin stimulus, hypertrophy and hyperplasia

In life-long oncogenicity studies of these H2-receptor antagonists, as well as with the H+,K+-ATPase inhibitor omeprazole, gastric enterochromaffin-like cell (ECL cell) hyperplasia and carcinoids have been found. The purpose of this paper is to summarize available evidence for the Gastrin Hypothesis to explain the development of ECL-cell. 類腸嗜鉻細胞( Enterochromaffin-like cells ),常簡稱ECL細胞( ECL cells )是一種胃黏膜上的神经分泌细胞,常分布於胃壁細胞附近。ECL細胞能分泌組織胺,輔助胃酸的分泌。這種細胞被認為屬於一種 腸道內分泌細胞 ( 英语 : enteroendocrine cells ) 。 參 AC in ECL cells stimulates gastric acid secretion via the actions of histamine acting at the parietal cell and in whole animals leads to proliferation of ECL cells when administered chronically.

Enterochromaffin-like (ECL) cells through histamine and X cells that secrete ghrelin activate parietal cells via paracrine and neural pathways, respectively. Gastrin secreted from G cells binds directly on parietal cells or stimulates acid secretion mediated by histamine release from ECL cells

  4. At similar gastrin levels, ECL-cell hyperplasia of the same magnitude developed during both ranitidine and omeprazole treatment. Antrectomy prevented the development of ECL-cell hyperplasia during omeprazole treatment, indicating that the hyperplasia was not due to the drug treatment per se, but rather to the hypergastrinemia. Both the hypergastrinemia and the ECL-cell hyperplasia were found to be reversible
  5. There is experimental support for the view that sympathetic nerve stimulation may activate the ECL cells directly as well as indirectly: the sympathetic transmitters noradrenaline and adrenaline are capable of acting directly on β-adrenergic receptors on the ECL cells (Lindström et al. 1997; Lindström & Håkanson, 2001), but there is also evidence suggesting that they may activate ECL cells in situ in an indirect manner (through vasoconstriction-evoked ischaemia) (Norlén et al. 2001.

ECL cells synthesize and secrete histamine.These cells are stimulated by the hormones gastrin (not depicted in the adjacent diagram) and pituitary adenylyl cyclase-activating peptide.G cells are stimulated by vagal stimulation through the neurotransmitter gastrin-releasing peptide; this causes the G cells to secrete gastrin, which in turn stimulates ECL cells to release histamine Proteins participating in vesicular docking and fusion have been identified in the nervous system. Such proteins appear to be important for the molecular regulation of exocytosis also in non-neuronal cells. The enterochromaffin-like (ECL) cells of the gastric acid-secreting (oxyntic) mucosa secrete histamine and chromogranin A-derived peptides, such as pancreastatin. Using immunohistochemistry.

ECL cells are numerous in the rat stomach. They produce and store histamine and chromogranin-A (CGA)-derived peptides such as pancreastatin and respond to gastrin with secretion of these products. Numerous electron-lucent vesicles of varying size and a few small, dense-cored granules are found in the cytoplasm. Using confocal and electron microscopy, we examined these organelles and their. Gastrin is a powerful stimulator of ECL cells in situ (Håkanson et al. 1974, 1994; Kitano et al. 2000b). As expected, it was found to mobilize ECL-cell histamine equally well on either side of the stomach . Food intake is known to cause vagal excitation and gastrin release. This is followed by stimulation of the ECL cells ECL cells were used without any prior stimulation, and their size, cytoplasmic complexity and autofluorescence were characterized. The ECL cell is a small, dense cell (8-10 µm) that contains abundant granules and secretory vesicles storing histamine and presents high cytoplasmic complexity [32,33,35]

ECL cells: biology and pathobiology

The enterochromaffin-like (ECL) cell in the oxyntic mucosa has a key role in the regulation of gastric secretion since it synthesizes and releases the histamine regulating the acid secretion from the parietal cell. Gastrin is the main regulator of the ECL cell function and growth. Long-term hypergastrinemia induces ECL cell hyperplasia, and if continued, neoplasia. ECL cell carcinoids occur in. ECL cells are histamine-containing endocrine/paracrine cells in the oxyntic mucosa of the stomach. They play a key role in the control of acid secretion because of their ability to secrete histamine, which stimulates adjacent acid-producing cells (for reviews see Håkanson et al. 1994, 1998).Like most peptide hormone-producing cells, ECL cells contain chromogranin A(CGA) and/or CGA-derived.
