Enteroendocrine cells
From Wikipedia, the free encyclopedia
Enteroendocrine cells are specialized endocrine cells of the gastrointestinal tract. They produce hormones such as serotonin[1], somatostatin, motilin, cholecystokinin, gastric inhibitory peptide, neurotensin, vasoactive inhibitory neuropeptide, and enteroglucagon.
Most enteroendocrine cells are found in the islets of Langerhans, but they are also found in other locations. For example, the G cells (which secrete gastrin) are located primarily in the stomach.[2]. Enteroendocrine cells are also found in the duodenum.[3]
Enterochromaffin-like cell and enterochromaffin cells are also considered enteroendocrine cells.[4]
