Abstract

Dendritic cells in the skin, called Langerhans cells, are the obvious candidates for transporting antigen from the epidermis to the lymph nodes and for activating T cell defense. However, as Serbina and Pamer discuss in their Perspective, at least in the case of viral antigens, it seems that other dendritic cell subsets residing in the dermis are the most important players in T cell-mediated defense against viral infection of the skin.
