• Background: CD152, also known as CTLA-4, is homologous to the costimulatory molecule CD28. (Ref.1,2) Like CD28, the CD152 molecule binds the family of B7 counter-receptors (CD80/B7-1 and CD86/B7-2) on antigen-presenting cells. (Ref.3) CTLA-4 is not expressed on resting T lymphocytes but is induced 2-3 days following T-cell stimulation via the T cell receptor (TCR) complex. (Ref.1,3,4) Whereas CD28 provides a positive costimulatory signal, CD152/CTLA-4 is a negative regulator of T-cell activation, possibly by inhibiting tyrosine kinase signalling through the TCR through its association with tyrosine phosphatases such as SHP-2. (Ref.1,5,6)
