NK cell effector functions require YTHDF2.(A) Representative histograms showing expression of the indicated molecules in splenic NK cells from Ythdf2WT and Ythdf2ΔNK mice. (B and C) Representative plots (B) and quantification (C) of IFN-γ expression by splenic NK cells from Ythdf2WT and Ythdf2ΔNK mice when stimulated with or without IL-12 plus IL-18 or YAC-1 mouse lymphoma cells (n = 6 per group; at least three independent experiments). (D) Mice were treated with an injection of poly(I:C) (200 µg i.p.) for 18 h. Poly(I:C)-activated NK cells were isolated from the spleen and cocultured with MHC class I–deficient RMA-S cells at a ratio of 5:1, 2.5:1, and 1.25:1. Cytotoxicity of NK cells was evaluated by standard 51Cr release assays (n = 3 per group; at least two independent experiments). Data are shown as mean ± SD and were analyzed by two-way ANOVA with Šídák post-test. **, P < 0.01; ***, P < 0.001; ****, P < 0.0001. E:T, effector:target.
