(HCV) is a single-stranded positive-sense RNA hepatotropic virus. Despite cellular defenses, HCV is able to replicate in hepatocytes and to establish a chronic infection that could lead to severe complications and hepatocellular carcinoma. An important player in subverting the host response to HCV infection is the viral nonstructural protein NS5A, which, in addition to its role in replication and assembly, targets several pathways involved in the cellular response to viral infection.
