An MHC- II Molecule on an Antigen-Presenting Cell Dendritic Cell Presenting a Bound Viral Epitope to a Naive T4-Lymphocyte with a Matching TCR/CD4 on its Surface

Naive T4-lymphocytes via the unique T-cell receptors and CD4 molecules on their surface recognize peptide epitopes from exogenous antigens bound to MHC-II molecules on antigen presenting dendritic cells. Different T-cell receptors recognize different epitopes.
