Fig. 4From: Isobavachalcone inhibits Pseudorabies virus by impairing virus-induced cell-to-cell fusionIBC inhibits PRV replication at the cell-to-cell fusion step. a RK13 cells were transfected with gB, gH, gL and EGFP expression plasmids, and 6 h later, the medium was replaced with medium containing either ethanol or the indicated doses of IBC. Cell-to-cell fusion was analyzed by fluorescence microscopy. b gB expression was evaluated at the indicated IBC concentrations. c Adenovirus replication was not influenced by IBCBack to article page
