    • A composition comprising an interleukin-15(IL-15) protein and peptides specific to HCV(hepatitis C virus) is provided to activate cell mediated immunity by activating cytotoxic T lymphocytes and natural killer cells from an HCV infected patient, recruit memory T cells as effective T cells and decrease regulatory T cells significantly by overcoming immunosuppression caused by TGF-beta, thereby effectively preventing and treating chronic hepatitis and liver cancer caused by HCV virus. A pharmaceutical composition for preventing or treating chronic hepatitis or liver cancer caused by HCV comprises an IL-15 protein or a gene encoding the same and peptides having amino acid sequences described as SEQ ID : NOs. 1 to 10 and is characterized in that the IL-15 activates cytotoxic T lymphocytes(CTL) specific to the HCV. The composition further comprises at least one selected from the group consisting of cytokines such as GM-SCF, IL-12, IL-7 an IL-2, costimulatory molecules such as CD40 ligand, 4-1BB ligand, Flt-3 ligand, hsp(heat shock protein), B7-1, B7-2 and MICA/B, anti-viral agents and antibodies.
    • 提供包含白细胞介素-15(IL-15)蛋白和HCV特异性肽(丙型肝炎病毒)的组合物,通过激活来自HCV感染患者的细胞毒性T淋巴细胞和天然杀伤细胞来激活细胞介导的免疫,将记忆T细胞作为 通过克服由TGF-β引起的免疫抑制,显着降低调节性T细胞,从而有效预防和治疗由HCV病毒引起的慢性肝炎和肝癌。 用于预防或治疗由HCV引起的慢性肝炎或肝癌的药物组合物包含IL-15蛋白或编码该基因的基因和具有SEQ ID NO:所示氨基酸序列的肽。 1至10,其特征在于IL-15激活特异于HCV的细胞毒性T淋巴细胞(CTL)。 组合物还包含选自细胞因子如GM-SCF,IL-12,IL-7和IL-2中的至少一种,共刺激分子如CD40配体,4-1BB配体,Flt-3配体,hsp (热休克蛋白),B7-1,B7-2和MICA / B,抗病毒剂和抗体。
