Protocol for inducing epidermis-specific gene deletion and establishing a UVB-irradiated skin inflammation model

When skin is exposed to ultraviolet B (UVB) radiation, damaged keratinocytes release double-stranded RNA to trigger an inflammatory response. Here, we present a protocol to induce epidermal-specific Zfp750 gene-deficient mice and establish a UVB-induced skin inflammation model. We detail procedures for detecting gene expressions in the epidermis by quantitative reverse-transcription PCR (RT-qPCR) and analyzing changes in skin immune cell subsets after UVB radiation using flow cytometry. For complete details on the use and execution of this protocol, please refer to Liu et al.¹.
