EOMES and neoplasm: Although we already observed accelerated tumor growth in both Tbx21ΔNK/ΔNK mice and EomesΔNK/ΔNK mice compared with control mice, we found that both Tbx21ΔNK/ΔNK mice and EomesΔNK/ΔNK mice displayed similar tumor growth as control mice after CD8+ T cell depletion (Figure 5A,B), indicating that NK‐expressed T‐bet and Eomes‐mediated tumor control was dependent on CD8+ T cells.
