The present invention provides isolated peptides having the amino acid sequence of SEQ ID NO: 34 or fragments thereof, which bind to HLA antigen and induce cytotoxic T lymphocyte (CTL). The present invention further provides peptides which include one, two, or several amino acid insertions, substitution or addition to the aforementioned peptides or fragments, but still have the cytotoxic T cell inducibility. Further provided are nucleic acids encoding any of these aforementioned peptides as well as pharmaceutical substances or compositions including any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical substances or compositions of the present invention may be used for treating cancer or tumor.

The invention is directed to methods of screening for HLA antibodies comprising detecting antibodies specific for native HLA antigens and denatured HLA antigens. The invention also provides for method of predicting whether a transplant recipient has an increased risk for rejecting the transplanted organ.

Isolated peptides derived from SEQ ID NO: 21 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 above 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, AML, bladder cancer, breast cancer, cervical cancer, cholangiocellular carcinoma, CML, colorectal cancer, esophagus cancer, gastric cancer, gastric diffuse-type cancer, lung cancer, lymphoma, prostate cancer, SCLC and soft tissue tumor.

Isolated peptides composed of the amino acid sequence of SEQ ID NO: 33 or fragments thereof that bind to HLA antigens and have cytotoxic T lymphocyte (CTL) inducibility and thus are suitable for use in the context of cancer immunotherapy, more particularly cancer 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 agents, substances and compositions including 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.

The invention is directed to methods of screening for HLA antibodies comprising detecting antibodies specific for native HLA antigens and denatured HLA antigens. The invention also provides for methods of removing antibodies specific for denatured HLA antigens or antibodies specific for native HLA antigens from a serum sample. In addition, the invention also provides for method of predicting whether a transplant recipient has an increased risk for rejecting the transplanted organ.

The present invention provides isolated peptides or the fragments derived from SEQ ID NO: 18, 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 the present invention can be used for treating cancer.

The present invention provides isolated peptides or the fragments derived from SEQ ID NO: 35, 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.

Disclosed is a peptide consisting of the identical amino acid sequence or a substantially identical amino acid sequence to the amino acid sequence depicted in SEQ ID NO:4, wherein the peptide binds to an HLA antigen and is recognized by cytotoxic T cells. The peptide of the present invention can be used in vivo or in vitro as an agent for inducing CTL, that is, cancer vaccine, and exerts therapeutic or ameliorating effects on tumors such as osteosarcoma, renal cancer, and others. The peptide of the present invention is also useful as a tumor marker directed to tumors such as sarcoma, renal cancer, and others.

The present invention provides isolated peptides having the amino acid sequence of SEQ ID NO: 43 or immunologically active fragments thereof, which bind to HLA antigen and have cytotoxic T lymphocyte (CTL) inducibility. The present invention further provides peptides which include one, two, or several amino acid insertions, substitution or addition to the aforementioned peptides or fragments, but still have the cytotoxic T cell inducibility. Further provided are nucleic acids encoding any of these aforementioned peptides as well as pharmaceutical agents and compositions including any of the aforementioned peptides or nucleic acids. The peptides, nucleic acids, pharmaceutical agents and compositions of this invention may be used for treating cancer or tumor.

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.
