Core Tip
Core tip: Hepatitis C virus (HCV)-specific cytotoxic T lymphocyte (CTL) response plays an essential role in controlling acute HCV infection but its implication in treatment-induced viral control is controversial. During interferon/ribavirin treatment, HCV traces persist after sustained viral response (SVR) and this correlates with an activated HCV-specific CTL response, suggesting the necessity of this response to obtain an indefinite viral control. Current data propose that viral suppression during interferon/ribavirin treatment and during direct-acting anti-viral regimes could affect HCV-specific CTL restoration. Moreover, the features of this CTL response during treatment could have a predictive value on SVR outcome.
