The upregulating Tregs in tumors was associated with the compromised therapeutic efficiency of PD-L1 treatment. A The Foxp3 IHC assay for the tumor tissue in (B). The pictures were magnified for 400 times. Scale bar: 50 μm. B The Foxp3 IHC assay for the spleen in the corresponding host of tumors in (B). The pictures were magnified for 400 times. Scale bar: 50 μm. C The detection of Tregs in the tumors of (B) with flow cytometry. The Tregs was defined as CD45+CD3+CD4+CD25+Foxp3+
