Summary

  • HCV-associated cell damage seems to be largely mediated by the host immune response
    • The hallmark of liver damage associated with HCV infection is a lympho-mononuclear infiltrate mostly represented by CD8+ T cells that are thought to play a major role in viral containment
    • Intrahepatic CD4+ and CD8+ cells are specific for different structural and nonstructural HCV antigens[Koziel 1992; Schirren 2000]
