In vivo proliferation of hepadnavirus‐infected hepatocytes induces loss of covalently closed circular DNA in mice
Marc Lutgehetmann, Tassilo Volz, Anne Köpke, Tim Broja, Eike Tigges, Ansgar W. Lohse, Eberhard Fuchs, John M. Murray, Joerg Petersen, Maura Dandri – 23 June 2010 – Chronic hepatitis B virus (HBV) infection is maintained by the presence of covalently closed circular DNA (cccDNA), the template of viral transcription and replication. In quiescent hepatocytes, cccDNA is a stable molecule that can persist throughout the hepatocyte lifespan.
