LL-37: Antimicrobial peptide
LL-37, also known as hCAP18, is the C-terminal part of the only human cathelicidin identified to date called human cationic antimicrobial protein (hCAP).
LL-37 exhibits a variety of immunomodulatory functions such as bactericidal action, chemotaxis, activation of chemokine secretion and antisepsis effect [1].The synthetic LL-37 peptide has been shown to suppress the inflammatory response induced by LPS and other TLR ligands [2].
