Type of secretory epithelial cell found in the small bowel within crypts of Lieberkühn and, to an extent, on the right side of the colon. They are thought to play a role in the innate immunity of the bowel through the production of immunoregulatory and antimicrobial proteins including the defensins.[1] Dysfunction of the Paneth cells has been linked to the inflammatory bowel disease.[2] The presence of Paneth cells in biopsies of the left side of colon is regarded as pathological and due to chronic inflammation.
