FIG. 4.
Influenza virus infection results in differential IRF3 nuclear translocation in Calu-3 cells. Polarized Calu-3 cells were infected with viruses at an MOI of 1. Cells were fixed and stained for influenza virus NP (green) and IRF3 (red) at 8 h p.i. (A) Immunofluorescent staining of virus-infected cells. (B) Assessment of rate of infection and IRF3 nuclear translocation in virus-infected cells. Error bars indicate standard deviations.
