Zika virus replication and cytopathic effects in liver cells.

ABSTRACT: Zika virus (ZIKV) has emerged globally as an important pathogen, since it has been recognized as a cause of microcephaly and other neurologic processes and sequalae in newborns. The virus shares homology with Hepaciviruses and therefore may be a cause of hepatitis. We sought to characterize ZIKV replication in hepatocyte-derived cell lines. Huh7.5 and HepG2 cells were infected with ZIKV and replication potential was evaluated by multiple methods including plaque assay, qRT-PCR, negative-strand ZIKV RNA production, and ZIKV NS1 protein production. Growth curves in cells and supernatant were compared to replicative capacity in Vero cells. Overall, viral replication in both hepatocyte lines approximated that observed in the Vero cells. Cell cytopathology was observed after 3 days of infection
