Abstract:
The present invention provides isolated peptides or the fragments derived from SEQ ID NO: 42, which bind to an HLA antigen and induce cytotoxic T lymphocytes (CTL). The peptides may include one of the above mentioned amino acid sequences with substitution, deletion, or addition of one, two, or several amino acids sequences. The present invention also provides pharmaceutical compositions including these peptides. The peptides of this invention can be used for treating cancer.
Abstract:
The present invention provides KOC1-derived epitope peptides having the ability to induce cytotoxic T cells. The present invention further provides polynucleotides encoding the peptides, antigen-presenting cells presenting the peptides, and cytotoxic T cells targeting the peptides, as well as methods of inducing the antigen-presenting cells or CTLs. The present invention also provides compositions and pharmaceutical compositions containing them as an active ingredient. Further, the present invention provides methods of treating and/or preventing cancer, and/or preventing postoperative recurrence thereof, using the peptides, polynucleotides, antigen-presenting cells, cytotoxic T cells or pharmaceutical compositions of the present invention. Methods of inducing an immune response against cancer are also provided.
Abstract:
Isolated IMP-3-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 promiscuously bind to MHC class II molecules and induce IMP-3-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, chronic myelocytic leukemia, colon cancer, rectum cancer, esophageal cancer, gastric diffuse-type cancer, non-small-cell lung cancer (NSCLC), small-cell lung cancer (SCLC), lymphoma, osteosarcoma, ovarian cancer, renal carcinoma, soft tissue tumor, testicular tumor, and HNC.
Abstract:
Peptide vaccines against cancer are described herein. In particular, isolated epitope peptides derived from the KNTC2 gene that elicit CTLs and thus are suitable for use in the context of cancer immunotherapy are provided. The inventive peptides encompass both KNTC2-derived peptides 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 CTL inducibility of the original sequences. Further provided are polynucleotides encoding such peptides as well as pharmaceutical compositions that include any such peptides or polynucleotides as active agents. Antigen-presenting cells and isolated CTLs that target such peptides, as well as methods for inducing the antigen-presenting cell, or CTL are also provided. Furthermore, the present invention provides methods for the treatment and/or prophylaxis (i.e., prevention) of cancers (tumors), and/or the prevention of a metastatic- or post-operative recurrence thereof, as well as methods for inducing CTLs, methods for inducing anti-tumor immunity, using the peptides derived from KNTC2, polynucleotides encoding the peptides, or antigen-presenting cells presenting the peptides, or the pharmaceutical compositions of the present invention.
Abstract:
The present invention provides peptides having an amino acid sequence as set forth in SEQ ID NO: 7, 8, 9, 10, 11, 12, 192, 195, 197, 209, 225, 226, 228, 230, 240, 241, 243, 244, 249, 253, 254 or 255, as well as peptides having the above-mentioned amino acid sequences in which 1, 2, or several amino acids are substituted, deleted, or added, wherein the peptides possess cytotoxic T cell inducibility. The present invention also provides drugs for treating or preventing a disease associated with the over-expression of MPHOSPH1 and/or DEPDC1, e.g. cancers, containing these peptides as an active ingredient. The peptides of the present invention can also be used as vaccines.
