Persistence of HCV in Quiescent Hepatic Cells Under Conditions of an Interferon-Induced Antiviral Response

We developed a cell culture system using hepatoma cells to study persistent HCV infection during the type I or type III IFN-induced antiviral response. The level and range of the antiviral responses were associated with the differentiation status of the cells. We propose that HCV exploits the stochastic nature of the response of hepatocytes to IFN to sustain persistence.
