The stability of secreted, acid-labile H77/JFH-1 hepatitis C virus (HCV) particles is altered by patient isolate genotype 1a p7 sequences.
Secreted infectious particles generated by the genotype 2a JFH-1 hepatitis C virus infectious clone are resistant to acidic pH, whereas intracellular virions remain acid-labile. Thus, JFH-1 particles are thought to undergo pH maturation as they are secreted from the cell. Here, we demonstrate that both infectious intracellular and secreted genotype 1a (H77)/JFH-1 chimaeric particles display enh...
متن کاملAnalysis of Immumoreactivity of Heterologously Expressed Non-structural Protein 4B (NS4B) from Hepatitis C Virus (HCV) Genotype 1a
Background: Detection of hepatitis C virus specific antibodies is the initial step in chronic HCV diagnosis. HCV NS4B is among the most immunogenic HCV antigens and has been widely used in commercial Enzyme Immunoassays (EIA). Additionally, NS4B, a key protein in the virus replication, can be an alternative target for antiviral therapy. Objectives: Development of a new method for high-level ex...
متن کاملThe p7 polypeptide of hepatitis C virus is critical for infectivity and contains functionally important genotype-specific sequences.
The role of the hepatitis C virus (HCV) p7 protein in the virus life cycle is not known. Previous in vitro data indicated that this 63-aa polypeptide is located in the endoplasmic reticulum and has two transmembrane domains (TMDs) connected by a cytoplasmic loop; the amino- and carboxyl-terminal tails are oriented toward the endoplasmic reticulum lumen. Furthermore, recent in vitro studies sugg...
متن کاملScreening of hepatitis C virus inhibitors using genotype 1a HCV replicon cell lines.
Hepatitis C virus (HCV) replicons are the primary tools for identifying and evaluating anti-HCV compounds during drug discovery research. Genotype 1a and 1b are the most common genotypes in North America and Europe. These genotypes display significant genetic divergence (∼20% at the nucleotide level and ∼14% at the amino acid level), which can translate into marked differences in drug susceptib...
متن کاملIsolation and Characterization of Highly Replicable Hepatitis C Virus Genotype 1a Strain HCV-RMT
Multiple genotype 1a clones have been reported, including the very first hepatitis C virus (HCV) clone called H77. The replication ability of some of these clones has been confirmed in vitro and in vivo, although this ability is somehow compromised. We now report a newly isolated genotype 1a clone, designated HCV-RMT, which has the ability to replicate efficiently in patients, chimeric mice wit...
