The skin is a major surface organ that translates external signals from the environment into local and systemic immune responses. As such, it is also strongly involved in fighting against cutaneous pathogens transmitted by arthropod vectors to the host. By harboring various skin-resident as well as highly motile immune cells and unique molecules, the skin orchestrates resulting immune responses against pathogens. Only an understanding of the complexity of skin immunity will lead to a better assessment of vector-induced alterations of resulting antipathogen immunity.

Dendritic cells (DC) are key elements of the immune system. In peripheral tissues, they function as sentinels taking up and processing antigens. After migration to the draining lymph nodes, the DC either present antigenic peptides by themselves or transfer them to lymph node-resident DC. The skin is the primary interface between the body and the environment and host's various DC subsets, including dermal DC (dDC) and Langerhans cells (LC). Because of their anatomical position in the epidermis, LC are believed to be responsible for induction of adaptive cutaneous immune responses. The functions of LC and dDC in the skin immune system in vivo are manifold, and it is still discussed controvers…
