Abstract
Ultraviolet rays are a potential threat to nature. It can accelerate skin aging by causing skin damage, cell infiltration, and inflammation. The present study investigated UV-irradiated mouse skin through single-cell sequencing. We observed that UV-irradiated mouse skin mainly induced inflammation of fibroblasts and demonstrated differential gene expression. Cell prediction revealed the significance of macrophages in tissue repair. Furthermore, cell culture studies substantiated vitamin D-induced inhibitory effect on skin inflammation. These findings thus indicate some references for skin photo-protection.
