CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor involved in the activation of cytotoxic T cells (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It consists of four different chains. In mammals, this complex contains one CD3γ chain, one CD3δ chain, and two CD3ε chains. These chains bind to the T cell receptor (TCR) and CD3-zeta (ζ chain) to generate activation signals in T lymphocytes. TCR, CD3-zeta and other CD3 molecules together make up the TCR complex. CD3 is mainly used as a drug target in cancer research. Because CD3 is required for T cell activation, CD3 can be a target for the efficacy of immunosuppressive therapy in type 1 diabetes and other autoimmune diseases.
