[Deciphering the links between hepatic viruses and interferons: molecular interactions and therapeutic implications].

Interferons (IFNs) are cytokines that play a key role in the innate immune response, possessing antiviral, antiproliferative, and immunomodulatory properties. Currently, IFNs are used clinically as treatments for lymphomas, multiple sclerosis, and chronic viral infections such as hepatitis B, C, D, and E virus infections. HEV infection can lead to fulminant hepatitis, while chronic infections with HBV, HCV, and HDV are the leading global causes of hepatocellular carcinoma.
