Interestingly, we found that in the CB2-/- mice, while macrophages and PMN-MDSCs showed no differences between groups, anti-tumor eosinophils and M-MDSCs were significantly decreased (p = 0.031 and p = 0.02, respectively), and DCs were increased two-fold (p = 0.0008, Figure 7B,C). This evidence concerns the gene CNR2 and neoplasm.
