Differentiated epithelial cells of the INTESTINAL MUCOSA, found in the basal part of the intestinal crypts of Lieberkuhn. Paneth cells secrete GROWTH FACTORS, digestive enzymes such as LYSOZYME and antimicrobial peptides such as cryptdins (ALPHA-DEFENSINS) into the crypt lumen.

Paneth cells represent one of the four major epithelial lineages in the mouse small intestine. It is the only lineage that migrates downward from the stem-cell zone located in the lower portion of the crypt of Lieberkühn to the crypt base. Mature Paneth cells release growth factors, digestive enzyme …

The presence of lysozyme and α-defensins in Paneth cell granules suggested a mucosal immune role years ago , and recent studies implicate the lineage directly in enteric host defense.Paneth cell ontogeny is independent of luminal bacteria, bacterial antigens, or dietary constituents, as shown by normal Paneth cell development in germ-free mice, in Although Paneth cell dysfunction has yet to be shown to directly cause speciﬁc disease states, links have been made between Paneth cells and the development of inﬂammatory bowel disease (IBD) (15, 27). One connection involves the observed reduction in expression of certain Paneth cell-derived defensin proteins in patients with IBD (27). Paneth cells are cells in the small intestine epithelium, alongside goblet cells, enterocytes, and enteroendocrine cells. Some can also be found in the cecum and appendix . They are below the intestinal stem cells in the intestinal glands (also called crypts of Lieberkühn ) and the large eosinophilic refractile granules that occupy most of their cytoplasm .

Named for the 19th-century Austrian physiologist Joseph Paneth, the cell has one nucleus at its base Paneth-celler är specialiserade celler som finns i slemhinnan i tarmsystemet, särskilt i mikroskopiska strukturer som kallas körtlar eller krypter från Lieberkühn. De innehåller flera viktiga ämnen i deras cytoplasma, inklusive enzymer, mineraler och granuler.
