Immunopharmacology Comments
CD2 is a cell surface glycoprotein expressed on most human T cells and natural killer (NK) cells [3] as well as by the majority of T cell lymphomas and leukemias. CD2 functions as a cell adhesion and co-stimulatory molecule. It is known to bind lymphocyte function-associated antigen-3 (LFA-3/CD58), a surface molecule expressed by antigen presenting cells and epithelial cells. The CD2/CD58 interaction promotes the initial stages of cell contact and facilitates T-cell receptor (TCR) triggering. CD2 is used as a specific marker for T cells and NK cells, and to distinguish B cell neoplasms from T cell lymphomas and leukemias.
