1. The glands contain mucus cells and G cells that secrete gastrin . 2. This results in higher levels of gastrin and stomach acid being secreted. 3. Dipeptides activate G-cells found in the stomach to secrete gastrin . 4. Its release is stimulated by gastrin and acetylcholine and inhibited by somatostatin. 5. The diagnosis may be supported by high serum gastrin levels ( ). 6. In addition, the source of the increased gastrin production must be discovered. 7. These include serotonin, neurotensin, cholecystokinin ( CCK ), and gastrin . 8. The receptor is called the gastrin -releasing peptide ( GRP ) receptor. 9. Gastrin is a hormone produced by enteroendocrine G cells in the pyloric glands.10. Other than gastrin , these hormones all act to turn off the stomach action.
