Description: The antimicrobial peptide LL-37 is the only known member of the cathelicidin family of peptides expressed in humans. LL-37 is a multifunctional host defense molecule essential for normal immune responses to infection and tissue injury. hCAP-18 (the only member of the cathelicidin AMP family in humans) contains an N-terminal domain, a cathelin domain and a C-terminal LL-37 domain. LL-37 is extracellularly cleaved from hCAP-18 by proteinase 3 and belongs to the class of linear alpha peptides. LL-37 owes its name to the fact that it consists of 37 amino acids that begin with two leucine residues. Human LL-37 is able to defend against various bacterial and fungal pathogens. The host defense peptide LL-37 has emerged as a novel modulator of tumor growth and metastasis in carcinogenesis of various types of cancers. LL-37 is an antimicrobial peptide able of inducing various effects. It acts as an anti- and pro- inflammatory factor. Cathelicidins are able to directly and selectively destroy membranes of various microbes and cancer cells, but they do not attack normal cells. The role of cathelicidins in cancer is double-sided. They play an important role in killing cancer cells and may provide a new possibility for the development of cancer therapeutics. However, they also can participate in carcinogenesis. Due to its activity spectrum LL-37 could be applied in pharmacotherapy. Cathelicidin peptides could serve as a template for the development of modern anti-microbial and anti-viral drugs. LL-37 is an excellent candidate to develop into therapeutics for infected wounds.
