Core Tip
Core tip: The interactions between hepatitis C virus (HCV) and the host immune system in the liver play a key role in the immunopathogenesis of HCV-induced diseases. We showed here that (-)-epigallocatechin-3-gallate (EGCG) treatment could significantly increase the poly I:C-induced expression of TLR3, RIG-I and interferon (IFN)-λ1 in JFH-1-Huh7 cells. In addition, supplementation with EGCG enhanced poly I:C-mediated viral inhibition in JFH-1-Huh7 cells at both RNA and protein levels. Further investigation of the mechanisms showed that EGCG treatment significantly enhanced the poly I:C-induced expression of IFN-regulatory factor 9 and several IFN-stimulated genes. It would be interesting to investigate the possible use of EGCG in combination with current antiviral drugs for HCV therapy.
