Caveolin-1 is important for infection by virions and ISVPs. 293 cells were transfected with empty vector or vector expressing dominant-negative caveolin-1. Cells were infected with T1L virions or ISVPs 24 h after transfection and then fixed and stained for μNS at 24 hpi. The number of transfected cells that were also μNS positive (infected) was determined by flow cytometry. The relative percentage of infected cells compared to empty vector (pEGFP-N1)-transfected controls is displayed. Error bars represent the standard errors of the means from three independent experiments.
