Supertype epitopes, oligonucleotides coding the same which induce effective CTL response against HCV and the use thereof

摘要

The present invention relates to a supertype epitope which effectively induce a cell-mediated immune response and its use, specifically, a supertype epitope which effectively induce the cytotoxic T lymphocytes specific to HCV and come from conservative region of a HCV polyprotein, an expression vector comprising the oligonucleotide coding the said supertype epitope, a vaccine composition comprising the said supertype epitope or the said expression vector and its use for treatment of hepatitis C. The HCV supertype epitope of the present can be applied to various individuals because it binds to various HLA molecule and can induce antigen-specific immune response, be used to develop therapeutics for hepatitis C by virus hepatitis C and the vaccines for a liver disease related to that as a strong and effective tool, the expression vector comprising the oligonucleotide coding a HCV supertype epitope and the DNA vaccine comprising it can be used as a strong and effective tool for immune response suppressed hepatitis and liver disease related to that.
