Description
LL-37 is the only human cathelicidin-derived antimicrobial peptide and a widely used tool compound in innate-immunity research. Laboratory investigators study LL-37 for its membrane-interacting antimicrobial activity, immunomodulatory signaling, chemotactic effects on immune cells, and its role in host-defense and wound-environment models in vitro and in preclinical systems. It is examined for interactions with bacterial membranes, biofilm models, and Toll-like receptor signaling. Supplied for in-vitro and laboratory research only — not for human or veterinary use.
