The comprehensive examination of the tumor cells remaining after killing assay—96 h or 120 h after impedance assay respectively—revealed that besides killing IL-2/IL-12/IL-18 alone is able to instruct γδ T cells to drive cancer cells also into senescence and terminal growth arrest, as recently shown by us as a consequence and combinational effect of IFN-γ and TNF-α secreted by TH1 immune effector cells [40]. The gene discussed is IFNG; the disease is neoplasm.
