Figure 24-48Recognition by T cells of foreign peptides bound to MHC proteins

Cytotoxic T cells recognize foreign peptides in association with class I MHC proteins, whereas helper T cells recognize foreign peptides in association with class II MHC proteins. In both cases, the peptide-MHC complexes are recognized on the surface of an antigen-presenting cell or a target cell.
