Depletion of CD4+CD25+ regulatory T cells can promote local immunity to suppress tumor growth in benzo[a]pyrene-induced forestomach carcinoma

Figure 8 Expression of Foxp3 protein of RLNs (A) and PLNs (B) in BaP-only-treated mice at wk 32 and quantified by flow cytometry (C). Foxp3 expression was determined as described in Materials and Methods. The histogram demonstrates FITC-conjugated Foxp3 staining (solid peak) and isotype control (hollow peak). ^aP < 0.05 vs control mice.
