Hepatitis C virus (HCV) is a global public health problem that mediates a persistent infection
in nearly 200 million people. HCV is efficient in establishing chronicity due in part to the
inefficiency of the host immune system in controlling and counteracting HCV-mediated
evasion strategies. HCV persistence is linked to the ability of the virus to suppress the RIG-I
pathway and interferon production from infected hepatocytes, thus evading innate immune
defenses within the infected cell. This review describes the virus and host processes that …
Hepatitis C virus (HCV) is a global public health problem that mediates a persistent infection in nearly 200 million people. HCV is efficient in establishing chronicity due in part to the inefficiency of the host immune system in controlling and counteracting HCV-mediated evasion strategies. HCV persistence is linked to the ability of the virus to suppress the RIG-I pathway and interferon production from infected hepatocytes, thus evading innate immune defenses within the infected cell. This review describes the virus and host processes that regulate the RIG-I pathway during HCV infection. An understanding of these HCV–host interactions could lead to more effective therapies for HCV designed to reactivate the host immune response following HCV infection.
