Description
LL-37 is the only cathelicidin antimicrobial peptide produced by humans, a 37-amino-acid fragment cleaved from the precursor protein hCAP-18. Its dual activity — direct antimicrobial action against bacteria alongside immune-modulatory signalling — makes it a distinct research subject from the thymic and pineal peptides elsewhere in this catalogue, sitting instead at the intersection of innate immunity and wound-healing research.
Because LL-37 is naturally present in skin, gut, and mucosal tissue, it’s frequently studied in dermatological and gut-barrier research alongside its antimicrobial-resistance research applications, an active area given rising interest in alternatives to conventional antibiotics.
