| 摘要 |
The invention provides HCV fusion proteins that include a mutated NS3 protea se domain, 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 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 t o immunize a mammal against HCV.
