    • Isolated LY6K-derived epitope peptides having Th1 cell inducibility are disclosed herein. Such peptides can be recognized by MHC class II molecules and induce Th1 cells. In preferred embodiments, such a peptide of the present invention can be promiscuously bind to MHC class II molecules and induce LY6K-specific cytotoxic T lymphocytes (CTLs) in addition to Th1 cells. Such peptides are thus suitable for use in enhancing immune response in a subject, and accordingly find use in cancer immunotherapy, in particular, as cancer vaccines. Also disclosed herein are polynucleotides that encode any of the aforementioned peptides, APCs and Th1 cells induced by such peptides and methods of induction associated therewith. Pharmaceutical compositions that comprise any of the aforementioned components as active ingredients find use in the treatment and/or prevention of cancers or tumors including, for example, bladder cancer, cervical cancer, cholangiocellular carcinoma, esophageal cancer, gastric cancer, non-small cell lung cancer (NSCLC), osteosarcoma, pancreatic cancer, soft tissue tumor and head-and-neck malignant tumor(HNMT).
    • 本文公开了具有Th1细胞诱导能力的分离的LY6K衍生的表位肽。 这样的肽可被MHC II类分子识别并诱导Th1细胞。 在优选的实施方案中,本发明的这种肽可以与MHC II类分子混合结合,并诱导除了Th1细胞之外的LY6K特异性细胞毒性T淋巴细胞(CTL)。 因此,这样的肽适合用于增强受试者的免疫应答,并因此在癌症免疫治疗中尤其是用作癌症疫苗时使用。 本文还公开了编码由这些肽诱导的上述肽,APC和Th1细胞中的任何一种的多核苷酸以及与其相关的诱导方法。 包含任何上述组分作为活性成分的药物组合物可用于治疗和/或预防癌症或肿瘤,包括例如膀胱癌,宫颈癌,胆管细胞癌,食道癌,胃癌,非小细胞肺 癌症(NSCLC),骨肉瘤,胰腺癌,软组织肿瘤和头颈恶性肿瘤(HNMT)。

    • 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,两个或几个氨基酸被取代,缺失,插入或添加,只要这些修饰版本保留所需的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。
