Clathrin-mediated endocytosis was not involved in EMCV infection Chlorpromazine treatment had no effect on EMCV replication. BHK-21 cells were treated with chlorpromazine, followed by incubation with EMCV at 0.1 MOI. At 9 hpi, cellular lysates or culture medium was collected, and virus replication assay was assessed by WB (a) and endpoint titration (b). Cell viability assay was performed to evaluate the cytotoxicity of the chlorpromazine (c). Pitstop-2 had also no effect on EMCV replication. BHK-21 cells were treated by Pitstop-2 as indicated above and infectivity was assessed by WB (d) and endpoint titration (e). Cell viability assay was performed to evaluate the cytotoxicity of the Pitstop-2 (f). Cultures treated with medium were used as negative control
