To accomplish this function, dendritic cells are equipped with highly efficient mechanisms to detect pathogens, to capture, process and present antigens, and to initiate T-cell responses.
These mechanisms are developmentally regulated during the DC life cycle in a process termed 'maturation', which was originally defined using Langerhans cells, a dendritic cells type of the epidermis.
Langerhans cells exist in the skin in an immature state dedicated to capturing antigens, and in the subcutaneous lymph nodes in a mature state dedicated to presenting those antigens to T cells. The phenotypic changes undergone by Langerhans cells during maturation, and the correlation of these changes with tissue localization, have been generally considered a paradigm for all dendritic cells.
