Fig. 5: P2X7 and A2A combined antagonism decreases P2X7 and A2A expression in the metastatic niche.

A–J BALB/c mice were injected intravenously with CT26 Luc2 cells and treated intraperitoneally with placebo, AZ10606120 (2 mg/Kg), SCH58261 (1 mg/Kg), or a combination of both drugs. Percentage of lung cells positive for P2X7 A and A2A F staining (n = 4).
