Illustration of a cell membrane with a T cell receptor (dark blue, centre) in complex with an MHC (major histocompatibility complex) class II-peptide complex (purple). The T cell receptor activates the immune response to antigens in T cells. The antigen (light green) is a peptide from a tumour cell, bacteria or virus. At centre left is a CD4 protein (light blue). After binding to the MHC-antigen complex, The T cell receptor (blue) sends a signal cascade through an attached G-protein into the T-lymphocyte cell, that activates an immune response.

Activation of T-cell immune response, illustration. Array of proteins interacting on the surface membranes of a T-cell (across bottom) and an antigen presenting cell (APC, across top). Shown here is the interaction of MHC-II (red) with the T-cell receptor (TCR, blue), and CD4 (light blue) and B7-1 (orange) with CD-28 (dark blue), activating T-cells. The interaction of B7-1 (orange) with CTLA-4 (purple) and PD-L1 (yellow) with PD-1 (purple) deactivates T-cells. T-cells are a key part of the immune system.
