Hence the skin provides defense in depth against will infection . </P> <P> The skin acts as a barrier, a kind of sheath, made of several layers of cells and their related glands . The skin is a dynamic organ that contains different cells which contains elements of the innate and the adaptive immune system which are activated when the tissue is under attack by invading pathogens . Shortly after infection, the immune adaptive response is induced by dendritic cells (Langerhans cells) present in the epidermis; they are responsible to capture, process, and present the antigens to T lymphocytes in local lymphoid organs . As result, T lymphocytes express the CLA molecule . Lymphocytes move to the epidermis where they reside as memory T cells, they will thus be activated and will trigger an inflammatory response .
