FIG. 2.

Effects of various drugs on infection of VCMs by RDV. (A) VCMs were incubated for 30 min with 400 μM dansylcadaverine, 4 mM chlorpromazine, 400 μg/ml genistein, and 20 nM bafilomycin A1, as indicated, or without drugs (control) and then inoculated with RDV. Cells were fixed and processed for immunofluorescence staining with virus-specific IgG conjugated to FITC. Bars, 35 μm. (B) VCMs were treated with various concentrations of dansylcadaverine, chlorpromazine, genistein, and bafilomycin A1, as indicated. Viral infection was quantified as the percentage of FITC-stained, drug-treated cells relative to the number of untreated control cells. The data shown are the means and standard deviations of the results from three independent experiments.
