LL-37 (CAP18), the only human antimicrobial peptide that has been identified in the cathelici-din gene family, is produced in neutrophils and also induced in keratinocytes during inflammatory skin disorders [17, 43]. In vivo, LL-37 provides protection against necrotic skin infection caused by group A streptococci and it also exerts antimicrobial activity against a wide variety of Gram-positive and Gram-negative bacteria [52]. Similar to defensins, LL-37 plays multiple roles in the fight against pathogens: in addition to its antibiotic effect, it has the potential to recruit mast cells, neutrophils, mono-
