Background: LL-37 is a peptide belonging to the cathelicidin family of antimicrobial peptides. Recent investigations have suggested that the expression of antimicrobial peptides is an important mechanism for resistance to microbial infection.
Objective: The aim of this study was to determine whether LL-37 is expressed in papillomavirus-infected epidermis from patients with condyloma acuminatum or verruca vulgaris.
