Supplementary Figure S5 shows that MOC2 tumor-bearing mice display a preferential TH2 phenotype, as demonstrated by an increased secretion of IL-4, particularly when stimulated in vitro with MOC2 parental or MOC2-CIITA cells, while MOC2-CIITA vaccinated mice express a preferential TH1 phenotype when stimulated in vitro with either parental MOC2 or, more importantly, with MOC2-CIITA cells. This evidence concerns the gene CIITA and neoplasm.
