T-cell receptor MHC complex. Computer model showing the structure of a T-cell surface glycoprotein CD4 (purple) complexed to the H-2 class II histocompatibility antigen A-K alpha chain (green) beta chain (yellow) and ovotransferrin (red). CD4 is a receptor found on T-cell white blood cells of the immune system. Antigens (foreign proteins) are presented to T cell receptors by MHC molecules to effect an immune response. | |
