Primary induction of ISGs by CMV and gB contributes directly to the antiviral response. GRE cells were treated as indicated (interferon, 100 U/ml). At 6 h posttreatment, the inoculum was removed and the monolayers were challenged with approximately 100 PFU of VSV per well. Plaque formation was visualized by crystal violet staining at 48 h postinfection.
