Three new studies report genetic variants near IL28B, which encodes interferon-λ3 (interleukin 28B), are associated with response to treatment of chronic hepatitis C virus infection with interferon-alfa/ribavirin combination therapy. This renews interest in how interferons suppress viremia and could lead to improved clinical decisions for chronic HCV infection treatment based on individual genotype.
