Morphogenesis of Infectious Hepatitis C Virus Particles
More than 170 million individuals are currently infected with hepatitis C virus (HCV) worldwide and are at continuous risk of developing chronic liver disease. Since a cell culture system enabling relatively efficient propagation of HCV has become available, an increasing number of viral and host factors involved in HCV particle formation have been identified. Association of the viral Core, whi...
متن کاملRecombinant infectious bursal disease virus carrying hepatitis C virus epitopes.
The delivery of foreign epitopes by a replicating nonpathogenic avian infectious bursal disease virus (IBDV) was explored. The aim of the study was to identify regions in the IBDV genome that are amenable to the introduction of a sequence encoding a foreign peptide. By using a cDNA-based reverse genetics system, insertions or substitutions of sequences encoding epitope tags (FLAG, c-Myc, or hep...
متن کاملConstruction and characterization of infectious intragenotypic and intergenotypic hepatitis C virus chimeras.
Chronic liver disease caused by infection with hepatitis C virus (HCV) is an important global health problem that currently affects 170 million people. A major impediment in HCV research and drug development has been the lack of culture systems supporting virus production. This obstacle was recently overcome by using JFH1-based full-length genomes that allow production of viruses infectious bot...
متن کاملApolipoprotein E but not B is required for the formation of infectious hepatitis C virus particles.
Our previous studies have found that hepatitis C virus (HCV) particles are enriched in apolipoprotein E (apoE) and that apoE is required for HCV infectivity and production. Studies by others, however, suggested that both microsomal transfer protein (MTP) and apoB are important for HCV production. To define the roles of apoB and apoE in the HCV life cycle, we developed a single-cycle HCV growth ...
متن کاملImmunization with hepatitis C virus-like particles protects mice from recombinant hepatitis C virus-vaccinia infection.
We have recently demonstrated that immunization with hepatitis C virus-like particles (HCV-LPs) generated in insect cells can elicit both humoral and cellular immune responses in BALB/c mice. Here, we evaluate the immunogenicity of HCV-LPs in HLA2.1 transgenic (AAD) mice in comparison to DNA immunization. HCV-LP immunization elicited a significantly stronger humoral immune response than DNA imm...
