Acquired Immunity
Dendritic Cells
Dendritic cells reside in the skin, lymph nodes, and tissues throughout the body. Most dendritic cells are Recognition . That is, they ingest, process, and present antigens, enabling helper T cells to recognize the antigen. Dendritic cells present antigen fragments to T cells in the lymph nodes. Another type of dendritic cell, the follicular dendritic cell, is present in lymph nodes and presents unprocessed (intact) antigen that has been linked with antibody (antibody-antigen complex) to B cells. Follicular dendritic cells help B cells respond to an antigen. After T and B cells are presented with the antigen, they become activated.
