WebIn mouse small bowel, the bactericidal cryptdin 1–6 peptides are specific to Paneth cells, and cryptdin-4 is the most potent of the known mouse cryptdins (3). Studies of mice lacking matrilysin (matrilysin-deficient), MMP-7,1 a metalloproteinase that activates Paneth cell pro-cryptdins, have shown that the resulting deficiency in activated WebCryptdins constitute the primary bactericidal activity The majority of microbicidal peptide activity in Paneth cell secretions can be attributed to cryptdins.

"Cryptdin is a portmanteau of crypt and defensin. Defensins are 2-6 kDa, cationic, microbicidal peptides active against many Gram-negative and Gram-positive bacteria, fungi, and enveloped viruses, containing three pairs of intramolecular disulfide bonds. See more Alpha defensins are a family of mammalian defensin peptides of the alpha subfamily. In mammals they are also known as cryptdins and are produced within the small bowel. Cryptdin is a portmanteau See more HNP-1, HNP-2 and HNP-3 are encoded by two genes DEFA1 and DEFA3 localized at chromosome 8, location 8p23.1. DEFA1 and DEFA3 encode identical peptides except the conversion of the first amino acid from alanine in HNP-1 to aspartic acid in See more Cryptdins are the protein products of a related family of highly polymorphic genes that are specifically expressed by mouse Paneth cells at the base of intestinal crypts. They were first characterized as products of cDNAs derived from mouse small intestinal … See more With the ability to kill gram-positive and gram-negative bacteria, fungi, spirochetes and some enveloped viruses, cryptdins are classified as … See more Initially human alpha defensin peptides were isolated from the neutrophils and are thus called human neutrophil peptides.
