    • Isolated peptides derived from SEQ ID NO: 42 and fragments thereof that bind to an HLA antigen and induce cytotoxic T lymphocytes (CTL) and thus are suitable for use in the context of cancer immunotherapy, more particularly cancer vaccines, are described herein. The inventive peptides encompass both the afore-mentioned amino acid sequences and modified versions thereof, in which one, two, or several amino acids are substituted, deleted, inserted or added, provided such modified versions retain the requisite HLA binding and/or CTL inducibility of the original sequences. Further provided are nucleic acids encoding any of the aforementioned peptides as well as pharmaceutical agents, substances and/or compositions that include or incorporate any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical agents, substances and compositions of this invention find particular utility in the treatment of cancers and tumors, including, for example, bladder cancer, breast cancer, cervical cancer, cholangiocellular carcinoma, CML, colorectal cancer, esophageal cancer, NSCLC, lymphoma, pancreatic cancer, prostate cancer, renal carcinoma and SCLC.
    • 衍生自SEQ ID NO:42的分离的肽及其与HLA抗原结合并诱导细胞毒性T淋巴细胞(CTL)的片段,因此适用于癌症免疫治疗,特别是癌症疫苗的上下文中。 本发明的肽包括上述氨基酸序列及其修饰形式,其中一个,两个或若干个氨基酸被取代,缺失,插入或添加,只要这些修饰版本保留必需的HLA结合和/或CTL诱导性 的原始序列。 还提供了编码任何前述肽的核酸以及包括或掺入任何前述肽或核酸的药物,物质和/或组合物。 本发明的肽,核酸,药物,物质和组合物在治疗癌症和肿瘤方面特别有用,包​​括例如膀胱癌,乳腺癌,子宫颈癌,胆管细胞癌,CML,结肠直肠癌,食管癌 ,NSCLC,淋巴瘤,胰腺癌,前列腺癌,肾癌和SCLC。

    • Peptide vaccines against cancer are described herein. In particular, the present invention describes epitope peptides derived from IQGAP3 that elicit CTLs. The present invention also provides established CTLs that specifically recognize HLA-A24 or HLA-A02 positive target cells pulsed with the peptides. Antigen-presenting cells and exosomes that present any of the peptides, as well as methods for inducing antigen-presenting cells are also provided. The present invention further provides pharmaceutical agents containing the IQGAP3 polypeptides or polynucleotides encoding thereof, as well as exosomes and antigen-presenting cells as active ingredients. Furthermore, the present invention provides methods for treating and/or prophylaxis of (i.e., preventing) cancers (tumors), and/or prevention of postoperative recurrence thereof, as well as methods for inducing CTLs, methods for inducing anti-tumor immunity, using the IQGAP3 polypeptides, polynucleotides encoding the polypeptides, exosomes or antigen-presenting cells presenting the polypeptides, or the pharmaceutical agents of the present invention. The cancers to be targeted include, but are not limited to, renal, esophageal, gastric, lung, breast, bladder and pancreatic cancer.
    • 本文描述了针对癌症的肽疫苗。 特别地,本发明描述衍生自引起CTL的IQGAP3的表位肽。 本发明还提供了特异性识别用肽脉冲的HLA-A24或HLA-A02阳性靶细胞的已建立的CTL。 还提供了呈递任何肽的抗原呈递细胞和外来体以及诱导抗原呈递细胞的方法。 本发明还提供含有IQGAP3多肽或其编码的多核苷酸以及作为活性成分的外来体和抗原呈递细胞的药剂。 此外,本发明提供了治疗和/或预防(即预防)癌症(肿瘤)和/或预防其术后复发的方法,以及诱导CTL的方法,诱导抗肿瘤免疫的方法,使用 IQGAP3多肽,编码多肽的多核苷酸,呈递多肽的外来体或抗原呈递细胞,或本发明的药剂。 要靶向的癌症包括但不限于肾,食管,胃,肺,乳腺,膀胱和胰腺癌。
