Though the infiltrating Ly6G+ NPs and Ly6C+ monocytes (Ly6C+ Mos) were comparable between the tumour tissues of WT and KO mice (Figure 1C), the expression of IL‐6 was moderately reduced in the infiltrating Ly6G+ NPs and Ly6C+ Mos (Figures 1D and S2c). This evidence concerns the gene IL6 and neoplasm.
