CD antigens, also called cluster of differentiation, are cell surface antigens of leukocytes and found in various immune cell populations like B cells, T cells, dendritic cells, natural killer (NK) cells, macrophages, monocytes, granulocytes and stem cells. CD antigens express different protein receptors on the cell surface, which help to determine the type and maturation stage of the detected cells. Thus they are important for immune reactions of organisms. Special drugs, such as monoclonal antibodies, have been designed to identify a particular type of CD antigens thus to attack only this specific type of cell.
