Figure 5

Synthetic diagram analyzing the impact of the IFN-γ production by peripheral blood mononuclear cells on the clinical outcome according to EBV status in blood and tumor tissue. PBMC EBV^- means <5 EBV DNA copies/μg, PBMC EBV⁺ means >5 EBV DNA copies/μg. Tumor EBV^- means <10 EBV DNA copies/μg and tumor EBV⁺ means >10 EBV DNA copies/μg. The intensity of the color is proportional to the amount of cytokine (IFN- γ or TNF-α) production (the black color indicates negative or control basal level, the red color indicates positive or high level).
