Zusammenfassung
Background: Direct-acting antiviral drugs (DAA) with or without Ribavirin or PEG-Interferon-alpha efficiently suppress and clear hepatitis C virus (HCV) infection. However, it remains controversial if robust HCV suppression also affects viral immune-escape and restores HCV-directed adaptive immune responses in vivo. Methods: In order to address these issues we monitored HCV-specific T-cell response from 20 chronically HCV infected patients throughout treatment with Sofosbuvir, Ribavirin and PEG-Interferon-alpha. HCV-specific CD4 and CD8 T-cell responses were identified by ex vivo HCV epitope pool stimulation and…
