CD2 （cluster of differentiation 2） is a cell adhesion molecule found on the surface of T cells and natural killer （NK） cells. It has also been called T-cell surface antigen T11/Leu-5, LFA-2, LFA-3 receptor, erythrocyte receptor and rosette receptor. It interacts with other adhesion molecules, such as lymphocyte function-associated antigen-3 （LFA-3/CD58） in humans, or CD48 in rodents, which are expressed on the surfaces of other cells. CD2 is a specific marker for T cells and NK cells, and can therefore be used in immunohistochemistry to identify the presence of such cells in tissue sections. The great majority of T cell lymphomas and leukaemias also express CD2, making it possible to use the presence of the antigen to distinguish these conditions from B cell neoplasms.
