Abstract
Hepatitis B is a worldwide health problem and the main cause of liver cirrhosis, liver failure, and liver cancer. The steady state of hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) in HBV infected hepatocytes and virus specific immune tolerance contribute to the chronic persistent infection and hard-to-cure of hepatitis B. The presently available therapeutics for hepatitis B can control viral replication, but rarely eliminate HBV surface antigen (HBsAg) or HBV cccDNA. The "cure" of hepatitis B, which is characterized by the HBsAg loss or HBsAg seroconversion, and cccDNA clearance, has been the goal of researchers for years. In recent years, with the robust progress in understanding the HBV pathogenesis and the rapid development of gene editing technology, the "cure" of hepatitis B becomes prospective. This paper aims to summarize the potential strategies for the "cure" of hepatitis B.
