Fig. 3From: Lycopene improves the efficiency of anti-PD-1 therapy via activating IFN signaling of lung cancer cellsThe combined therapy of lycopene and anti-PD-1 synergistically regulates cancer cell death cytokine. IFNγ+/CD8+ (a), perforin+/CD8+ (b), granzyme B+/CD8+ (d) population in tumor-infiltrated T cells was measured by flow cytometry analysis. *p < 0.05 vs. control, #p < 0.05 vs. Anti-PD-1 (n = 6)Back to article page
