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 ). The ECL cells are mainly located in the lower part of the gastric glands, well-positioned to deliver their histamine into the capillaries which flow past them and the parietal cells (Fig. 1). G-cell vid måltid. 40 likes på denna? Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell secreting histamine. N cell [ edit ] Located in the jejunum, N cells release neurotensin , and control smooth muscle contraction. 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. Definition från Wiktionary, den fria ordlistan. Hoppa till navigering Hoppa till sök.

Histamine (HA), contained in the enterochromaffin-like (ECL) cells of the gastric mucosa in animals, plays an important role in gastric acid secretion, although methods for its exact morphological

2013 — Histamin förmedlar sina cellfysiologiska verkningar via fyra G- projekt och ett europeiskt expertnätverk (COST Action BM0806: Till professionella histaminproducerande celler räknas MC, basofiler, ECL celler och. 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. Their function is unknown, in the sense that the peptide hormone they produce has not yet been identified. However, the ECL cells are active in the production and stor-
Histamine has two basic centres, namely the aliphatic amino group and whichever nitrogen atom of the imidazole ring does not already have a proton.Under physiological conditions, the aliphatic amino group (having a pK a around 9.4) will be protonated, whereas the second nitrogen of the imidazole ring (pK a ≈ 5.8) will not be protonated. The presence of gastrin stimulates parietal cells of the stomach to secrete hydrochloric acid (HCl)/gastric acid. This is done both directly on the parietal cell [failed verification] and indirectly via binding onto CCK2/gastrin receptors on ECL cells in the stomach, which then responds by releasing histamine, which in turn acts in a paracrine manner on parietal cells stimulating them to
1999-11-15 · 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 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.
