Targeted impairment of innate antiviral responses in the liver of chronic hepatitis C patients.

Innate sensing of viral infection activates a global defense response including type I interferon (IFN) and IFN-stimulated genes (ISGs) expression. We previously reported that HCV NS3/4A protease, an essential protein in viral polyprotein processing, can abrogate antiviral signaling pathways and effectors' response when ectopically expressed in human hepatocytes by cleaving antiviral adaptor CARDIF. However, whether HCV mediates evasion of innate immunity in patients with chronic infection remains unclear.
