Caffeic acid inhibits HCV replication via induction of IFN α antiviral response through p62-mediated Keap1/Nrf2 signaling pathway
In this study, we showed that CA could notably inhibit HCV replication. Mechanism study demonstrated that CA could induce HO-1 expression, which would trigger the IFNα antiviral response, and the antiviral effect of CA was attenuated when HO-1 activity was inhibited by SnPP (an HO-1 inhibitor). CA could also increase erythroid 2-related factor 2 (Nrf2) expression. When Nrf2 was knocked down by specific siRNA, HO-1 expression was concomitantly decreased while HCV expression was restored. Further study indicated that kelch-like ECH-associated protein 1 (Keap1) expression was decreased by CA in a p62/Sequestosome1 (p62)-depe...
