<p>Figure 7. PDE5 inhibition reverts MDSC suppressive pathways. Splenic CD11b+ cells from C26GM tumor-bearing mice were isolated and added to CFSE-labeled splenocytes containing either (A) naive HA-specific CD8+ (CL4) cells or (B) naive HA-specific CD4+ (6.5) cells. The cultures were stimulated for 4 d with the relevant peptide in the presence or absence of 50 µg/ml sildenafil. Proliferation was evaluated as CFSE dilution by FACS analysis. (C) Splenic CD11b+ cells were magnetically purified from B16GM tumor-bearing C57BL/6-NOS+/+ or C57BL/6-NOS–/– mice and added to CFSE-labeled splenocytes containing naive OVA-specific CD4+ T cells. The cultures were stimulated for 4 d with the relevant peptide in the presence or absence of 50 µg/ml sildenafil. Proliferation was evaluated as CFSE dilution by flow cytometry. Data derived from one of two independent experiments with similar results are reported. Error bar values are shown.
