LL-37: A Multifunctional Antimicrobial Peptide
LL-37 is the only human cathelicidin antimicrobial peptide derived from the CAMP gene. It is produced by epithelial cells, neutrophils, macrophages and other immune cells, where it contributes to innate immune defense against bacterial, viral, and fungal pathogens.
LL-37 is a cationic, amphipathic peptide that binds to negatively charged microbial membranes and disrupts them, which is considered its primary antimicrobial mechanism. In addition to direct antimicrobial activity, LL-37 also modulates immune responses and influences inflammatory signaling pathways.
Research shows that LL-37 also contributes to tissue repair and wound healing. Studies demonstrate that LL-37 promotes endothelial cell migration, angiogenesis, and re-epithelialization, supporting tissue regeneration and recovery. LL-37 additionally acts as a chemoattractant for immune cells, linking innate and adaptive immune responses.
