Dermcidin

Dermcidin is an antimicrobial peptide that is produced by human sweat glands. It was first identified in 2001 and is known to play a crucial role in the immune system's first line of defense against pathogens.

Function

Dermcidin is secreted into sweat and transported to the skin's surface, where it provides protection against invading microorganisms. It is effective against a broad range of bacteria, including E. coli, E. faecalis, S. aureus, and C. albicans.

Unlike other antimicrobial peptides, dermcidin does not rely on membrane disruption to kill bacteria. Instead, it forms channels in the bacterial membrane, which leads to an imbalance in ion concentrations and ultimately cell death.

Clinical significance

Dermcidin may have potential therapeutic applications, particularly in the treatment of antibiotic-resistant infections. However, more research is needed to fully understand its mechanisms of action and potential uses in medicine.
