Dermcidin-1L (DCD-1) is a 47-amino acid antimicrobial peptide (AMP). It is expressed in eccrine sweat glands, secreted into sweat at a concentration of 1-10µg/mL, and transported to the epidermal surface. Unlike most AMPs, which are cationic, DCD has a net negative charge.
DCD-1 displays antimicrobial activity thereby limiting skin infection by potential pathogens in the first few hours after bacterial colonization. Highly effective against E.coli, E.faecalis, S.aureus and C.albicans. Optimal pH and salt concentration resemble the conditions in sweat. Also exhibits proteolytic activity.
