Antigen-Presenting Cells

Medical Definition: Heterogeneous group of immunocompetent cells that mediates the cellular immune response by processing and presenting antigens to the T-cell receptor. Traditional antigen-presenting cells include MACROPHAGES; DENDRITIC CELLS; LANGERHANS CELLS; and B-LYMPHOCYTES. Follicular dendritic cells (DENDRITIC CELLS, FOLLICULAR) are also considered to be antigen-presenting cells by some authors.

Canadian Medical Guide Definition Dendritic Cells - Immunocompetent cells of the lymphoid and hemopoietic systems and skin. They are also called interdigitating, reticular, and veiled cells. They function morphologically and phenotypically by processing antigens or presenting them to T-cells, thereby stimulating cellular immunity.
