In the early (day 20) and late (day 77) stages of tumor development, the accumulation of CD11b+Ly6ChiLy6G- monocytic cells among CD11b+ cells were increased in WT mice treated or not with anti-IL-17 blocking antibody, compared with STAT1-/- mice (p < 0.001, Figure 4A,B). This evidence concerns the gene STAT1 and neoplasm.
