Increased IFNγ secretion by NK cells primed with VMAPRTLFL was observed in controls (Figure 5A) and patients (Figures 5B, C) compared with unstimulated and control peptide-stimulated cells in the presence of UM-SCC-2A target cells (Figures 5A, B) or of primary tumor cells (Figure 5C). This evidence concerns the gene IFNG and neoplasm.
