 Cathelicidin

Cathelicidin antimicrobial peptides (CAMP) "LL-37" and "FALL-39" are polypeptides that are primarily stored in the lysosomes of macrophages and polymorphonuclear leukocytes (PMNs); in humans, the "CAMP" gene encodes the peptide precursor CAP-18, which is cleaved into the active forms LL-37 and FALL-39.Cathelicidins serve a critical role in mammalian innate immune defense against invasive bacterial infection.
