[The analysis of immunoreactivity of individual B-cell epitopes of hepatitis C virus (Flaviviridae: Hepacivirus: Hepatitis С virus) NS4a antigen].

Introduction: Chronic viral hepatitis C (CHC) is a ubiquitous infectious disease, a significant limitation of which WHO attributes to the use of a new highly effective antiviral therapy. Previously, two B-cell epitopes were identified in NS4a antigen of the hepatitis C virus (HCV). It was shown that certain titers of antibodies (ABs) to the extended C-terminal epitope (1687-1718 a.
