New perspectives on the hepatitis B virus life cycle in the human liver

Abstract

The central role of the transcriptional template of the hepatitis B virus (HBV), covalently closed circular DNA (cccDNA), has been difficult to study in patients with chronic hepatitis B (CHB) infection. In this issue of the JCI, Zhang and colleagues reveal a mosaic distribution of viral antigens and nucleic acids and a mismatch between HBV cccDNA, RNA, and expression of the hepatitis B surface antigen (HBsAg). These unusual patterns varied over the natural history of CHB, prompting the authors to propose a new three-stage model of the HBV life cycle at the single-cell level.
