Synthetic Decapeptide Enhances Bacterial Clearance and Accelerates Healing in the Wounds of Restraint-Stressed Mice

Abstract

Wound healing is a complex process involving four transitional yet concurrent stages: coagulation, inflammation, cell proliferation/epithelialization and remodeling. These overlapping stages occur uneventfully in normal physiology. however,r during psychological stress, the inflammatory response can become dysregulated and result in increased susceptibility to bacterial infection and delayed wound closure. In our restraint stress model, cutaneous wounds of stressed SKH1 mice demonstrated significantly higher levels of bacterial load, and healing progresses at a rate 30% slower, than in non stressed mice. The purpose of this study was to test the hypothesis that a synthetic antimicrobial decapeptide (KSLW) enhances bacterial clearance during stress impaired healing in mice.
