IL28B Genotype Is Associated With Differential Expression of Intrahepatic Interferon-Stimulated Genes in Patients With Chronic Hepatitis C

Abstract

The good response IL28B variant was strongly associated with lower level ISG expression. The results suggest that IL28B genotype may explain the relationship between hepatic ISG expression and HCV treatment outcome, and this is independent of miR-122 expression. IL28B-type was not associated with intrahepatic IL28B messenger RNA expression in vivo. Further investigation of the precise molecular mechanism(s) by which IL28B genetic variation influences HCV outcomes is warranted.
