Hepatitis B virus taxonomy and hepatitis B virus genotypes [PDF]

World Journal of Gastroenterology, 2007
Hepatitis B virus (HBV) is a member of the hepadnavirus family. Hepadnaviruses can be found in both mammals (orthohepadnaviruses) and birds (avihepadnaviruses). The genetic variability of HBV is very high. There are eight genotypes of HBV and three clades of HBV isolates from apes that appear to be additional genotypes of HBV.

Hepatitis B Virus Mutants

Intervirology, 1999
During hepatitis B virus (HBV) infection, selection and takeover of mutant viruses are frequent events driven by both humoral and cellular host-immune response and antiviral therapy. Therefore, dynamic studies of the variations of viral mutants over time within the overall viral population in relation with the host-virus interactions are extremely ...

Drug-related mutational patterns in hepatitis B virus (HBV) reverse transcriptase proteins from Iranian treatment-Naïve chronic HBV patients [PDF]

, 2013
Background: Immunomodulators and Nucleotide analogues have been used globally for the dealing of chronic hepatitis B virus (HBV) infection. However, the development of drug resistance is a major limitation to their long-term effectiveness.

Augmented epigenetic repression of hepatitis B virus covalently closed circular DNA by interferon-α and small-interfering RNA synergy

mBio
The persistence of hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) is a key obstacle for HBV cure. This study aims to comprehensively assess the effect of interferon (IFN) and small-interfering RNA (siRNA) combination on the cccDNA ...
