As shown in Supplementary Figure S9B–S9D, opposite from the effect of IFN-γ neutralization, IL-17A neutralization decreased tumor number and load both in WT and SHP2CD4−/− mice, suggesting that IL-17A may counteract the effect of IFN-γ to promote tumor, even though it is overridden by IFN-γ. Here, IL17A is linked to neoplasm.
