LL-37 (CAP-18)
LL-37, a 37-amino-acid cathelicidin peptide, exhibits antimicrobial and immunomodulatory effects by disrupting bacterial membranes and modulating immune responses through receptors like FPRL1 and TLRs. It promotes wound healing, angiogenesis, and cytokine release while suppressing excessive inflammation, making it a candidate for treating infections, chronic wounds, and inflammatory disorders.
