Epitopes of hepatitis C virus
The invention provides compositions containing HCV epitopes, which are recognized by cytotoxic T lymphocytes. Such polypeptides are used in prophylactic vaccines, immunotherapies, and assays to monitor the progress or success of immune interventions. The compositions are optimized to elicit an immune response in a genetically-diverse population of individuals.
1. An immunogenic composition comprising a purified Hepatitis C Virus (HCV) polypeptide, wherein said HCV polypeptide is HLA-Cw7 restricted and consists of the amino acid sequence of SEQ ID NO:52.
2. An immunogenic composition comprising a purified Hepatitis C Virus (HCV) polypeptide, wherein said HCV polypeptide is HLA-A29 restricted and consists of the amino acid sequence of SEQ ID NO:51.
