title: Interferon-gamma response by peripheral blood mononuclear cells to hepatitis C virus core antigen is reduced in patients with liver fibrosis.
abstract: Liver fibrosis was correlated with immunological parameters. Peripheral blood mononuclear cells (PBMCs) from patients with low fibrosis scores had more [corrected] interferon (IFN)-gamma-producing cells than did patients with higher fibrosis scores, when stimulated with hepatitis C virus (HCV) core antigen. Irrespective of liver fibrosis score, cells from all cytomegalovirus (CMV)-seropositive patients had similar IFN-gamma responses, when stimulated by CMV antigen, so patients with fibrosis did not have a broad-spectrum immunodeficiency. IFN-gamma response by PBMCs to HCV core antigen may provide a useful marker of the severity of liver disease in patients with hepatitis C.
