Cevap
The correct answer is c. MHC I molecule.TCR (T cell receptor) on CD8+ T cells recognizes fragments of peptide bound in MHC I molecules. CD8+ T cells, also known as cytotoxic T cells, play a crucial role in the immune response by targeting and killing infected or cancerous cells. The TCR on CD8+ T cells specifically recognizes and binds to peptide fragments presented by MHC I molecules on the surface of infected or abnormal cells. This interaction triggers the activation and cytotoxic activity of the CD8+ T cells.
