IL10 and neoplasm: Although we observed slight increases in Il10 and Gzmb expression in DCs and NK cells (Fig. 5f,g), when we attempted to validate these results in vivo using tumor-bearing Pd1fl/fl and Pd1fl/flFoxp3ERT2Cre mice, no difference in IL-10 or GzmB protein expression in DCs or NK cells was found (Fig. 5h,i).
