    摘要: The invention provides a method of activating hepatitis C virus (HCV)-specific T cells, including CD4+ and CD8+ T cells. HCV-specific T cells are activated using fusion proteins comprising HCV NS3, NS4, NS5a, and NS5b polypeptides, polynucleotides encoding such fusion proteins, or polypeptide or polynucleotide compositions containing the individual components of these fusions. The method can be used in model systems to develop HCV-specific immunogenic compositions, as well as to immunize a mammal against HCV.

    摘要: Chimeric antigens derived from hepatitis B virus (HBV) and hepatitis C virus (HCV) are described which form virus-like particles when co-expressed with an excess of hepatitis B virus surface antigen (HBsAg). The chimeric antigens are fusion proteins containing an immunogenic peptide derived from an HCV protein coupled to the amino terminus of HBsAg. Also described are nucleic acid constructs and vectors for transfection of cells and expression of the chimeric antigens. The invention further provides methods for producing HBV/HCV virus-like particles containing the chimeric antigens, cell lines for producing the virus-like particles, combination vaccines containing the virus-like particles, and DNA vaccines that express the virus-like particles.
