One day after P14 cell transfer, recipient mice were infected intratumorally with an LCMV variant lacking the GP33-41 epitope (LCMV ΔGP33) or a wild-type LCMV (Cl-13) to determine whether the activation of virus-specific CD8+ T cells potentiates tumor control (Figure 3I). This evidence concerns the gene CD8A and neoplasm.
