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,^[1] LFA-3 receptor, erythrocyte receptor and rosette receptor.^[2]

Function

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.^[3]

In addition to its adhesive properties, CD2 also acts as a co-stimulatory molecule on T and NK cells.^[4]

Diagnostic relevance

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.^[5]

Classification

Due to its structural characteristics, CD2 is a member of the immunoglobulin superfamily; it possesses two immunoglobulin-like domains in its extracellular portion.^[4]

Interactions

CD2 has been shown to interact with CD2BP2,^[6] Lck^[7] and PSTPIP1.^[8]
