A complete understanding of the molecular features of humoral immune response could be of pivotal importance in the management of persistent viruses as HCV. In this study, 24 HCV-positive samples, characterized by classical virological parameters, are evaluated using a new assay for the quantitation of antibody subpopulations directed against discrete epitopes on surface glycoprotein E2, a key viral protein. The results, besides confirming the usefulness of this new approach, highlight the extreme heterogeneity of anti-HCV/E2 response as far as single epitopes are concerned. The specific epitopes under study are also demonstrated to be widely shared among different genotypes.
