The dendritic cell is one of the major means by which innate and adaptive immune systems communicate. It is believed that these cells shape the adpative immune response by the reacitons to microbila molecules or signals. Dendritic cells capture, process and present antignes, thus activating CD4+ and C3*+ naive T lymphoces. leading to the induction of primary immune responses, and derive their stimulatory potency form expression of MHC class I, MHC class II, and accesory moelcules, such as CD40, CD54, CD80, CD86, and T-cell activating cyctokines.
