We found that there was no difference between P0 and P3 cells in terms of CTL effector cytokine (IFN-γ) production of AH1-specific CTLs mixed with AH1-epitopic peptide–loaded tumor cells, suggesting that P0 and P3 cells had similar T cell activation capabilities and potentials to be recognized by the CTLs (Supplemental Figure 6B). The gene discussed is IFNG; the disease is neoplasm.
