An MHC- I Molecule on an Antigen-Presenting Cell Presenting a Bound Viral Epitope to a Naive T8-Lymphocyte with a Matching TCR/CD8 on its Surface

Naive T8-lymphocytes via the unique T-cell receptors and CD8 molecules on their surface recognize peptide epitopes from endogenous antigens bound to MHC-I molecules on antigen presenting cells (APCs). Different T-cell receptors recognize different epitopes.
