In anatomy, the<unk>  or<unk> astrin cell, is a type of cell in the stomach and duodenum that secretes<unk> astrin. It works in conjunction with<unk> astric chief cells and parietal cells.<unk> s are found deep within the pyloric<unk> lands of the stomach antrum, and occasionally in the pancreas and duodenum. The vagus nerve innervates the<unk> s.<unk> astrin-releasing peptide is released by the post-ganglionic fibers of the vagus nerve onto<unk> s during parasympathetic stimulation. The peptide hormone bombesin also stimulates<unk> astrin from<unk> s.<unk> astrin-releasing peptide, as well as the presence of amino acids in the stomach, stimulates the release of<unk> astrin from the<unk> s.<unk> astrin stimulates enterochromaffin-like cells to secrete histamine.<unk> astrin also targets parietal cells by increasing the amount of histamine and the direct stimulation by<unk> astrin, causing the parietal cells to increase HCl secretion in the stomach.
