Figure 5. IRF-1 promotes IFN-γ expression in infiltrating NK cells and NKT cells.

Representative images of FACS assay for IFN-γ expression in NKT cells (A), NK cells (B), CD3+T cells (C), CD4+T cells (D) and CD8+ T cells (E) of single cell suspensions prepared from same volume of tumors overexpressing IRF-1 (IRF-1) vs. negative control (NC). (F, G)The statistical summary of IFN-γ expression cells rate in tumors with IRF-1 vs. NC. Each data point (F & G) represents one mouse (n=5). Data represent mean ± SD, **p<0.01. (NS, no significant).
