The consequences of a hepatitis A virus (HAV) infection on cell-based antiviral responses and the interactions between virus and host cells resulting in persistent infections are poorly understood. In this report, we show that HAV does inhibit double-stranded (dsRNA)-induced beta interferon (IFN-beta) gene expression by influencing the IFN-beta enhanceosome, as well as dsRNA-induced apoptosis, ...
