Although the prevalence of HBV infection tributes to the persistence of HBV replication due to the bio- has decreased markedly with the effective application of logical mechanism of cccDNA formation, which itself remains ’ vaccines, it s still an arduous task to clear the hepatitis B unclear. Eliminating the cccDNA is critical to cure the HBV surface antigen after routine antiviral therapy, as the viral infection.8 rebound often occurs after therapy withdrawal. Therefore, the Recently, Zhu et al.9 conducted a systemic review of HBV 1 situation of dealing with HBV infection is still challenging. As cccDNA and its potential role as the therapeutic target of HBV such, eliminating HBV infection has become an important task infection. Pegylated-IFNa and nucleotide analogues (NAs) are for governments all over the world. In 2016, the Global Health the standard therapy methods, currently.

NAs can inhibit HBV replication important insight into the detailed action of the HBV lifestyle by targeting the viral RNA-dependent DNA polymerase, and that has promoted development of therapeutic strategies several NAs, such as lamivudine, entecavir, telbivudine and so against HBV infection. HBV infection begins with the low- on, have been approved for clinical use. Although an effective affinity interaction between HBV and the heparin sulfate antiviral response has been observed with the use of IFNa and proteoglycans located on the host hepatocytes, followed by NAs, the cccDNA still could not be cleared completely, at HBV binding to the sodium taurocholate cotransporting poly- 10 3 present. peptide and then its entry into the hepatocytes. The HBV 9 genome is a relaxed circular DNA with a length of 3.2 kb, Zhu et al. reviewed several gene therapy strategies that which can be transported into the nuclear compartment in have been proposed
