Explanation:
Detailed explanation-1: -Cells that present foreign antigens in the context of MHC can be recognized by antigen-sensitive cells such as CD8+ and CD4+ T cells. Cytotoxic CD8+ T cells recognize peptides on MHC class I molecules and CD4+ T cells recognize peptides binding to MHC class II molecules.
Detailed explanation-2: -CD4 and CD8 co-receptors on the surface of T cells. Cytotoxic T cells (TC) express CD8, which recognizes class I MHC proteins, whereas helper T cells (TH) express CD4, which recognizes class II MHC proteins.
