On the other hand, anti‐PD‐L1 immunotherapy induced similar tumor‐suppressive effects in EomesΔNK/ΔNK mice as in control mice (Figure 6F), indicating that NK‐expressed Eomes is required for NK cell support in the antitumor CD8+ T cell response but not for further response to anti‐PD‐L1 immunotherapy. The gene discussed is EOMES; the disease is neoplasm.
