    Production of Recombinant Hepatitis B virus (HBV) and Detection of HBV in Infected Human Liver Organoids
    Authors:  Tanvir Hossain, Shahla Romal and Tokameh Mahmoudi, date: 04/20/2022, view: 401, Q&A: 0

    The absence of long term, primary untransformed in vitro models that support hepatitis B virus (HBV) infection and replication have hampered HBV pre-clinical research, which was reflected in the absence of a curative therapy until recently. One of the limitations for in vitro HBV research has been the absence of high titer and pure recombinant HBV

    Generation, Maintenance and HBV Infection of Human Liver Organoids
    Authors:  Shahla Romal, Tanvir Hossain and Tokameh Mahmoudi, date: 03/20/2022, view: 905, Q&A: 0

    Hepatitis B virus (HBV) infection represents a major public health problem infecting approximately 400 million people worldwide. Despite the availability of a preventive vaccine and anti-viral therapies, chronic HBV infection remains a major health issue because it increases the risk of developing liver cirrhosis and hepatocellular carcinoma

    Quantification of Hepatitis B Virus Covalently Closed Circular DNA in Infected Cell Culture Models by Quantitative PCR
    Authors:  Bingqian Qu and Stephan Urban, date: 04/05/2019, view: 5389, Q&A: 0
    [Abstract] Persistence of the human hepatitis B virus (HBV) requires the maintenance of covalently closed circular (ccc)DNA, the episomal genome reservoir in nuclei of infected hepatocytes. cccDNA elimination is a major aim in future curative therapies currently under development. In cell culture based in vitro studies, both hybridization- and ...
    Sleeping Beauty Transposon-based System for Rapid Generation of HBV-replicating Stable Cell Lines
    Authors:  Jin-Wei Zheng, Jia-Li Cao and Quan Yuan , date: 07/05/2018, view: 6971, Q&A: 0
    [Abstract] The stable HBV-transfected cell lines, which based on stable integration of replication-competent HBV genome into hepatic cells, are widely used in basic research and antiviral drug evaluation against HBV. However, previous reported strategies to generate HBV-replicating cell lines, which primarily rely on random integration of exogenous DNA by ...
    In vitro Drug Susceptibility Assay for HBV Using Southern Blotting
    Authors:  Sung Hyun Ahn, Yong Kwang Park and Kyun-Hwan Kim, date: 04/20/2015, view: 9731, Q&A: 0
    [Abstract] Antiviral agents for the suppression of hepatitis B virus (HBV) have been used for treating chronic hepatitis B. However, the emergence of drug-resistant HBV is still a major problem for antiviral treatment. To identify and characterize the drug-resistant HBV, the construction of HBV replicon and in vitro drug susceptibility assay are ...
