Research Abstract

In addition to human β-defensins and LL-37, the cutaneous tissue also generates other antimicrobial agents, including psoriasin, dermcidin and catestatin. In this study project, we found that above antimicrobial agents activate and regulate various functions of human keratinocytes and mast cells. Thus, besides their microbiocidal properties, skin-derived antimicrobial agents might also participate in cutaneous host defense, inflammation and innate immune system.
