We evaluated the association between variations in hepatitis C virus (HCV) core protein and hepatitis severity in patients with chronic HCV infection who achieved remission without viral eradication and had a biochemical response to interferon (IFN) therapy, to evaluate the effect of HCV core sequence in the absence of the influence of host factors. METHODS. Using serum from 10 patients with a biochemical response and 10 patients with no response, we measured serum levels of interleukin (IL)-1 beta , IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IFN- gamma , and tumor necrosis factor- alpha before and after IFN therapy. Expression vectors with the core region were transfected into Huh7 cells, and cytokine induction was evaluated by reporter assay.
