ECL cells in the oxyntic mucosa of the mouse and rat stomach express CCK2 receptors, which enable them to respond to gastrin by the production and release of histamine. We have studied CCK2 receptor-deficient mice and rats subjected to pharmacological CCK2 receptor blockade in an attempt to demonstrate the importance of gastrin signaling for ECL-cell differentiation and proliferation.

addition to parietal ceils, enterochromaffin-like (ECL) ceils and D cells are known to be involved in the regulation of acid secretion from the fundic mucosa, and it is possible that, besides parietal cells, these cells possess PG receptors, thus being under the control of mucosal PG. 5

The e•ect of CCK2-receptor blockade was investigated by the use of YF476, a potent and selective CCK2 receptor antagonist, which is known to prevent gastrin from mobilizing ECL-cell histamine addition to parietal ceils, enterochromaffin-like (ECL) ceils and D cells are known to be involved in the regulation of acid secretion from the fundic mucosa, and it is possible that, besides parietal cells, these cells possess PG receptors, thus being under the control of mucosal PG. 5 Depletion of ECL-cell histamine resulted in an increase in the concentration of HDC mRNA. This was shown to be independent of gastrin since antrectomy did not prevent this increase in a-FMH-treated rats. The increase in HDC mRNA might be mediated via the auto-feedback H3 receptor on the ECL cell. By combining long-term hypergastrinemia with Abstract.

We used the mastomys rodent to generate an in vivo hypergastrinemia model using long-term histamine-2 receptor blockade (loxtidine 1 Acute CCK2 receptor blockade inhibits gastrin-evoked but not histamine-induced acid secretion. Studies both in vivo/in situ and in vitro have suggested that while acetylcholine seems capable of activating parietal cells, it does not affect histamine secretion from ECL cells. 19 timmar sedan · Pain receptors linked to the generation of energy-burning brown fat cells Vascular smooth muscle-derived Trpv1+ progenitors have found to be a source of cold-induced Enterochromaffin-like cells, located within the gastric glands of the stomach, release histamine that stimulates nearby parietal cells by binding to the apical H 2 receptor. Stimulation of the parietal cell induces the uptake of carbon dioxide and water from the blood, which is then converted to carbonic acid by the enzyme carbonic anhydrase. addition to parietal ceils, enterochromaffin-like (ECL) ceils and D cells are known to be involved in the regulation of acid secretion from the fundic mucosa, and it is possible that, besides parietal cells, these cells possess PG receptors, thus being under the control of mucosal PG. 5 2007-10-04 · Since the ECL cell exhibits all three classes of receptor we evaluated and compared the effects of the gastrin receptor antagonist, (YF476), lanreotide (SST agonist) and novel dopaminergic agents (BIM53061 and BIM27A760) on ECL cell histamine secretion and proliferation.

The circulating pancreastatin concentration is raised, was lowered when the action of gastrin on the ECL cells was blocked by the CCK2 receptor antagonists. The histamine- and pancreastatin- containing ECL cells in the acid-producing mucosa of the rat stomach operate under the control of circulating gastrin. The present work examines how cholecystokinin (CCK)-B/gastrin receptors regulate the activity of the ECL cells. The oxyntic mucosal histidine decarboxylase (HDC) activity and the circulating pancreastatin concentration are two markers for the Luminescence imaging is performed after 20 min incubation. 81 Applied to the monitoring of internalization of the adenosine A1 receptor (A 1 AR) and β 2 adrenergic receptor (β 2 AR) in live cells, a decrease of the luminescent signal is observed when internalized receptors are excluded from interactions with the cell‐impermeable LgBiT.

Discussion: It is proposed that the G-cells and the ECL cells are coupled by the couplet molecules gastrin and histamine and by a prior asymmetrical cell division . Regulation of ECL cell secretion.

cells called enterochromaffin-like (ECL) cells. ECL cells also have receptors for gastrin and acetylcholine, which stimulate histamine release. Histamine binds to the H2 receptor on the parietal cell, resulting in activation of adenylyl cyclase, which increases intra- cellular cyclic adenosine monophosphate (cAMP) and activates protein kinases that stimulate acid secretion by the H+/K+-ATPase.

Pulmonary neuroendocrine cells in the respiratory tract are known as bronchial Kulchitsky cells. The gastrin-ECL cell pathway has been investigated extensively in situ (gastric submucosal microdialysis), in vitro (isolated ECL cells) and in vivo (intact animals). Gastrin acts on CCK2 receptors to control the synthesis of ECL-cell histamine, accelerating the expression of the histamine-forming enzyme histidine decarboxylase (HDC) at both Activation of the enterochromaffin-like (ECL) cell is accepted as the main source of histamine participating in the regulation of acid secretion and is functionally and trophically controlled by gastrin, which is mediated by gastrin/CCK-2 receptors expressed on the ECL cell. Enterochromaffin-like (ECL) cells also bear gastrin receptors, and recent evidence indicates that this cell may be the most important target of gastrin with regard to regulating acid secretion. Stimulation of ECL cells by gastrin leads to histamine release, and histamine binding to H2 receptors on parietal cells is necessary for full-blown acid secretion .
