| Research Abstract |
Catestatin, initially believed to act as an neuroendocrine regulator, is an antimicrobial agent found in the skin keratinocytes and fibroblasts, and is over-expressed during wound healing and infection. In this study, we observed that Catestatin and the newly discovered antimicrobial peptides known as IDRs stimulated various functions of human keratinocytes and neutrophils, leading to the wound healing acceleration. Thus, in addition to their microbiocidal properties, skin-derived antimicrobial agents might also participate to the regulation of cutaneous host defense, inflammation and innate immune system through activation of keratinocytes.
