Influenza A virus infection reduced GFP fluorescence in lungs of SP-C^GFP mice. Representative false-colored In Vivo Imaging System images of lungs from one uninfected C57BL/6 mouse, one uninfected SP-C^GFP mouse, and one SP-C^GFP mouse each at 2 and 6 dpi (A) and effect of infection with influenza A/WSN/33 virus on GFP fluorescence intensity in isolated lungs from SP-C^GFP mice (n = 10/group, B). Red oval, area over which fluorescence was quantified. #P < 0.001 vs. uninfected mice. ‡P < 0.005 vs. 2 dpi. Data are presented as means ± SE.
