Adoptive transfer of CD62L+CD44− naïve OT1 CD8+ T cells to Tipe2ΔNK/ΔNK mice or control mice bearing MC38‐OVA tumors showed that donor‐derived tumor‐infiltrating OT1 CD8+ T cells in Tipe2ΔNK/ΔNK mice expressed higher levels of IFN‐γ and TNF‐α (Figure 3C,D). The gene discussed is CD8A; the disease is neoplasm.
