IFNG and neoplasm: The concentrations of IFN-γ (more than 573.72 ± 25.77 pg/mL; Figure 3D) and Gzm B (more than 1708.09 ± 48.47 pg/mL; Figure 3E) were significantly higher in the culture supernatant of SNK cells than in PBNK cells at an E:T ratio of 5:1 and the control group (tumor cells: 22.64 ± 5.95 pg/mL and SNK cells: 44.60 ± 4.53 pg/mL) (p < 0.05; Figure 3D,E).
