| 摘要 |
The invention provides truncated HCV NS5 polypeptides and fusion proteins comprising the truncated NS5 polypeptides, fused to at least one other HCV epitope derived from another region of the HCV polyprotein. The fusions can be used in methods of stimulating an immune response to HCV, for example a cellular immune response to HCV, such as activating hepatitis C virus (HCV)<specific T cells, including CD4<+> and CD8<+> T cells. The method can be used in model systems to develop HCV?specific immunogenic compositions, as well as to immunize a mammal against HCV. |
