conclusions this study demonstrated the detection of hcv-specific ifn-γ responses in hcv antibody and rna negative individuals, with a tendency for hcv-specific ifn-γ responses to be associated with hcv exposure. the potential role of hcv-specific ifn-γ responses in those who remained hcv rna negative is of value for the development of novel hcv therapeutics. objectives in a cohort of hcv antib...
