Research Abstract

The immune suppressive effect of UVB, which is a risk factor of skin cancer onset and is used as a remedy of skin inflammatory diseases, was studied. UVB-induced immune suppression was induced by the migration of epidermal Langerhans cells into lymph nodes. In addition, dermal dendritic cells located in the dermis were essential to induce the contact hypersensitivity response corresponding human contact dermatitis.
