The IFNγ ELISpot performed at 42 weeks after tumor injection in those mice that were still alive strongly suggests that the magnitude of TRP2-specific T cell response correlates with the survival increase (663, 403 and 62 mean SFC/106 cells in IDLV-hTRP2, LV-mTRP2, and IDLV-mTRP2, respectively). Here, IFNG is linked to neoplasm.
