How LL37 Works

LL-37 is the only human cathelicidin antimicrobial peptide. It adopts an amphipathic alpha-helical structure that directly disrupts microbial membranes through electrostatic interactions with negatively charged lipid bilayers, creating pores that cause bacterial lysis. Beyond direct antimicrobial activity, LL-37 modulates innate immunity by serving as a chemotactic agent for neutrophils, monocytes, and T-cells, promoting wound repair biology through keratinocyte migration and angiogenesis, and modulating TLR signaling.
