Based on the provided abstracts, information about the dermcidin (DCD) gene function is limited. The gene encodes a protein that functions as an antimicrobial peptide involved in innate immune responses. DCD expression can be upregulated in human hair follicles by synthetic odorants like Sandalore® through olfactory receptor OR2AT4 activation 1. This upregulation produces antimicrobial activity against various microorganisms, with Sandalore®-conditioned medium containing higher DCD content showing preferential activity favoring Staphylococcus epidermidis and Malassezia restricta over S. aureus and M. globosa, while exhibiting antimicrobial activity against Cutibacterium acnes 1. The study demonstrates that DCD production was previously thought to be exclusive to sweat and sebaceous glands, but can also occur in hair follicles when stimulated appropriately 1. However, the provided abstracts contain insufficient information about DCD's primary molecular mechanisms, detailed protein structure, broader physiological roles, or clinical disease relevance beyond its antimicrobial function in hair follicle microbiome management. Additional research would be needed to fully characterize this gene's complete functional profile.
