In this study, we found that neutralization of low-pH intracellular compartments by niclosamide not only inhibited the early stage of the DENV viral life cycle, such as viral RNA replication, independent of the entry step but also the late stage, specifically, the maturation of virus particles into infectious virions. Indeed, niclosamide treatment www.nature.com/scientificreports www.nature.com/scientificreports/ during the first 6 h of infection reduced DENV replication in BHK-21 cells harbouring dengue replicons to a level comparable to that of ribavirin, suggesting that the drug affects viral RNA replication and/or translation independent of its effect on entry, membrane fusion and genome release. ./cache/cord-355179-wmfwl2bh.txt ./txt/cord-355179-wmfwl2bh.txt
