Mice infected with a recombinant adeno-associated virus carrying a replication-competent hepatitis B virus genome (rAAV-HBV) via the intravenous route establish a persistent HBV replication in hepatocytes and develop immune tolerance. They serve as models to evaluate antiviral immunity and to assess potential therapeutic approaches for chronic HBV infection. Combining selected HBV variants and different mouse genotypes allows for addressing a broad spectrum of research questions. This …
