IFNγ increases the expression of iNOS but does not stimulate the intracellular redistribution of iNOS. Distribution of iNOS (red) within untreated (B6) or IFNγ-treated (B6/IFNγ) macrophages was visualized 20 h post-infection with gfp-expressing Salmonella (green). Insets show detailed intracellular distribution of iNOS and Salmonella. IFNγ-treated macrophages isolated from iNOS-deficient mice (iNOS/IFNγ) were used as controls. Original magnification of 1000×.
