T cell receptor B7 molecule 插畫檔

T cell receptor B7. Molecular model of the T cell receptor B7 bound to the viral Tax peptide and MHC class I molecule HLA-A2. T cell receptors are protein complexes found on the surface of a type of white blood cell called T lymphocytes (or T cells), part of the body's immune system. Antigens (foreign proteins) are presented to T cell receptors by MHC molecules to effect an immune response.
