And in the 1990s, it became known as a potent professional antigen presenting cell (APC), and it played an important role in immune induction and immunomodulation. Dendritic cells in the body make up only about 0.3% of the total circulating leukocytes, but are composed of heterogeneous populations with a phenotype distinct from macrophages. Dendritic cells are differentiated in that they are powerful antigen presenting cells, unlike B cells or macrophages with relatively weak antigen presenting ability.
