    • Isolated peptides composed of the amino acid sequence of the modified MELK epitope peptide or immunologically active fragments thereof that bind to HLA antigens and have higher cytotoxic T lymphocyte (CTL) inducibility than that of the wild type MELK epitope peptide and thus are suitable for use in the context of cancer immunotherapy or endometriosis immunotherapy, more particularly cancer or endometriosis vaccines are described herein. The present invention further provides peptides that include one, two, or several amino acid insertions, substitutions or additions to the aforementioned peptides or fragments, but yet retain the requisite cytotoxic T cell inducibility. Further provided are nucleic acids encoding any of these aforementioned peptides as well as pharmaceutical substances and compositions including any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical substances and compositions of this invention find particular utility in the treatment of cancers, tumors, and endometriosis.
    • 由修饰的MELK表位肽或其免疫活性片段的氨基酸序列组成的分离肽,其结合HLA抗原并且具有比野生型MELK表位肽更高的细胞毒性T淋巴细胞(CTL)诱导性,因此适用于 本文描述了癌症免疫治疗或子宫内膜异位症免疫治疗的背景,更特别的是癌症或子宫内膜异位症疫苗。 本发明进一步提供了肽,其包括前述肽或片段的一个,两个或几个氨基酸插入,取代或添加,但仍保留所需的细胞毒性T细胞诱导性。 进一步提供了编码这些上述肽中的任何一种的核酸以及包含上述肽或核酸中任何一种的药物物质和组合物。 本发明的肽,核酸,药物和组合物在癌症,肿瘤和子宫内膜异位症的治疗中具有特别的用途。
