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.
