Model describing the inhibition of HCV replication by andrographolide. Andrographolide induces p38 MAPK activation and subsequently increases Nrf2-mediated HO-1 expression, leading to the generation of biliverdin against HCV replication by enhancement of antiviral IFN responses and inhibition of HCV NS3/4A protease activity.
