| Outline of Final Research Achievements |
Interleukin-17 (IL-17) is a proinflammatory cytokine. The role of this cytokine in the wound healing process is not fully clarified. In this study, IL-17A knockout mice showed promoted wound healing and decreased neutrophil accumulation compared with wild-type mice, and the administration of recombinant IL-17A led to delayed wound closure, accelerated neutrophilic accumulation and improved wound repair with treatment of a neutrophil elastase inhibitor. Neutrophils, macrophages and gamma-delta T cels showed IL-17A expression after wounding in wild-type mice.
These results indicated that IL-17A hampared the wound healing process and neutrophilic inflammation caused by IL-17 led to impaired wound healing in skin.
