Ontogeny of hepatitis C virus (HCV) hypervariable region 1 (HVR1) heterogeneity and HVR1 antibody responses over a 3 year period in a patient infected with HCV type 2b.

Hypervariable region 1 (HVR1) sequences of 96 clones at six time-points representing 27 variants in two major and one minor group were identified in a patient with chronic hepatitis C virus (HCV) infection over 3 years. Major and selected minor variants were used to design synthetic peptides corresponding to the HVR1 C terminus. Peptide ELISA reactivity with IgG was plotted against the correspo...

Genetic and serological evidence for multiple instances of unrecognized transmission of hepatitis C virus in hemodialysis units.

We investigated the unrecognized patient-to-patient transmission of hepatitis C virus (HCV) in hemodialysis units by performing phylogenetic and serological analyses of hypervariable region 1 (HVR1) of HCV. Of the 62 patients in one center, 11 were positive for HCV RNA. A total of 24 HVR1 sequences, including the minor population of sequences of HCV isolates, from each patient were closely rela...

Hepatitis C virus lacking the hypervariable region 1 of the second envelope protein is infectious and causes acute resolving or persistent infection in chimpanzees.

Persistent infection with hepatitis C virus (HCV) is among the leading causes of chronic liver disease. Previous studies suggested that genetic variation in hypervariable region 1 (HVR1) of the second envelope protein, possibly in response to host immune pressure, influences the outcome of HCV infection. In the present study, a chimpanzee transfected intrahepatically with RNA transcripts of an ...

HVR1-mediated antibody evasion of highly infectious in vivo adapted HCV in humanised mice

OBJECTIVE HCV is a major cause of chronic liver disease worldwide, but the role of neutralising antibodies (nAbs) in its natural history remains poorly defined. We analysed the in vivo role of hypervariable region 1 (HVR1) for HCV virion properties, including nAb susceptibility. DESIGN Analysis of HCV from human liver chimeric mice infected with cell-culture-derived prototype genotype 2a reco...

Hepatitis C virus population dynamics in human lymphocytes and hepatocytes infected in vitro.

We previously found two cell lines (MT-2 and PH5CH) that were susceptible to hepatitis C virus (HCV) infection. Analysis of the infectivity of sera from HCV-positive blood donors for MT-2 and PH5CH cells suggested the cell tropism of HCV. To investigate further the cell tropism of HCV, the dynamics of HCV populations during culture were examined using three MT-2 clones and three PH5CH clones, i...
