parietal cell การใช้

• This creates a diffuse from the cytoplasm into the parietal cell canaliculi.
• Mucous neck cells are located within gastric glands, interspersed between parietal cells.
• The parietal cells secrete hydrochloric acid the main component of gastric acid.
• A big meal also kicks the parietal cells into overdrive, producing more acid.
• This is the major stimulus for acid secretion by parietal cells.
• Another important secretion of the parietal cells is intrinsic factor.
• The vagus normally stimulates the stomach's parietal cells to secrete acid and intrinsic factor.
• All three of these stimulate parietal cells to secrete hydrochloric acid and intrinsic factor.
• The pylorus also contains scattered parietal cells and neuroendocrine cells.
• Once present, acetylcholine activates G cells and parietal cells.
• Histamine also stimulates H + secretion from parietal cells.
• The presence of serum antibodies to parietal cells and to intrinsic factor are characteristic findings.
• Parietal cells contain an extensive secretory network ( called H + / K + ATPase.
• Gastrin acts on parietal cells directly and indirectly too, by stimulating the release of histamine.
• However the decrease in pH caused by activation of parietal cells further activates gastric chief cells.
• One, the parietal cells in the body of the stomach are stimulated to release H +.
• KCNE2 is also highly expressed in parietal cells of the gastric epithelium, also at the apical side.
• Intrinsic factor antibodies are much less sensitive than parietal cell antibodies, but they are much more specific.
• Chloride and hydrogen ions are secreted separately from the cytoplasm of parietal cells and mixed in the canaliculi.
• KCNE2 protein is most readily detected in the choroid plexus epithelium, gastric parietal cells, and thyroid epithelial cells.
