ABSTRACT:
The present invention is directed to a molecule comprising a polypeptide having substantial homology with a CTL epitope selected from the group consisting of ADLMGYIPLV (Core131-140; SEQ ID NO:1), LLALLSCLTV (Core178-187; SEQ ID NO:2), QLRRHIDLLV (SEQ ID NO:55), LLCPAGHAV (NS31169-1177; SEQ ID NO:26), KLVALGINAV (NS31406-1415; SEQ ID NO:28), SLMAFTAAV (NS41789-1797; SEQ ID NO:34), LLFNILGGWV (NS41807-1816; SEQ ID NO:35), and ILDSFDPLV (NS52252-2260; SEQ ID NO:42). Such molecules are used for the treatment and prevention of acute or chronic HCV hepatitis; suitable pharmaceutical compositions and methods using such compositions are disclosed.
