Research Abstract |
In this study, to investigate the function of B7-H1 on KC, we generated transgenic (tg) mice overexpressing B7-H1 under the control of human keratin 14 (K14) promoter (B7-H1 tg). In DNFB hapten-induced contact hypersensitivity model, it suggests that B7-H1 on KC may directly downregulate the effector function of CD8 T cells at skin inflammatory site. Furthermore, it indicates that B7-H1 on KC accelerates carcinogenesis by promoting epithelial-mesenchymal transition via down-regulation of E-cadherin on KC in a methylcholantrene(MCA)-induced model of squamous cell carcinoma(SCC).
