Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system .. immune system. immune system. antigen. antigen. present. Antigen presentation. They act as messengers between the innate and the adaptive immune systems .. innate. Innate immune system. Dendritic cells are present in those tissues that are in contact with the external environment , such as the skin -LRB- where there is a specialized dendritic cell type called the Langerhans cell -RRB- and the inner lining of the nose , lungs , stomach and intestines .. present. Antigen presentation. skin. skin. Langerhans cell. Langerhans cell. nose. Human nose. lungs. lungs. stomach. stomach. They can also be found in an immature state in the blood .. blood. blood. Once activated , they migrate to the lymph nodes where they interact with T cells and B cells to initiate and shape the adaptive immune response .. At certain development stages they grow branched projections , the dendrites that give the cell its name -LRB- δενδρον or dendron being Greek for `` tree '' -RRB- .. dendrites. Dendrite ( non-neuronal ). While similar in appearance , these are structures distinct from the dendrites of neurons .. dendrites. Dendrite ( non-neuronal ). Immature dendritic cells are also called veiled cells , as they possess large cytoplasmic ` veils ' rather than dendrites .. dendrites. Dendrite ( non-neuronal )
