Definitions
- the present invention relates to a peptide derived from MUC1, more specifically, an immunogenic peptide that presents an antigen to T cells through binding to a human leukocyte antigen, and a pharmaceutical composition for treating or preventing cancer using the same.
- Product, immunity-inducing agent, and method for producing antigen-presenting cells are included in the present invention.
- cancer cells In vivo, it is thought that cancer cells always occur accidentally, but usually a specific cancer antigen-exclusion reaction due to innate immunity occurs, and then a specific immune response is induced and lymphatic It is assumed that cancer cells are eliminated by spheres.
- HLA human leukocyte antigen
- lymphocytes In order for cancer cell-derived antigens to be recognized, human leukocyte antigen (HLA) present on the cell surface and lymphocytes must form a complex. HLA molecules that are major histocompatibility antigens are roughly classified into class I molecules (HLA-A type, B type, C type) and class II molecules (HLA-DP type, DQ type, DR type).
- CTLs cytotoxic T cells
- CTL epitopes cancer antigens consisting of 8 to 11 amino acids presented on HLA class I molecules on the surface of cancer cells receive T cell antigens on CTLs. It is induced by being specifically recognized by the body (TCR).
- JP-A-8-151396 discloses an oligopeptide comprising a specific amino acid sequence. Is described as having HLA binding properties.
- HLA binding properties Many peptides having HLA binding properties are known, but there is a further demand for peptides that can be used for the treatment or prevention of various cancers. Moreover, since HLA is a gene rich in polymorphism, there is also a demand for a multitype immunogenic peptide corresponding to a plurality of HLA types.
- the present invention has been made in view of the above circumstances, and is an immunogenic peptide that binds to an HLA class I molecule, particularly a peptide capable of inducing CTL, and a pharmaceutical composition for treating or preventing cancer using the same.
- An object of the present invention is to provide an immune inducer, a method for producing antigen-presenting cells, and the like.
- the present invention includes the following inventions.
- a peptide comprising 8 or more consecutive amino acid residues in the amino acid sequence represented by any of SEQ ID NOs: 1 to 12 and consisting of 11 or less amino acid residues.
- the peptide according to (1) wherein one or several amino acids are substituted, inserted, deleted or added in the amino acid sequence and have immunogenicity.
- the second amino acid is substituted with tyrosine, phenylalanine, methionine, tryptophan, valine, leucine or glutamine, and / or the C-terminal amino acid is substituted with phenylalanine, leucine, isoleucine, tryptophan, methionine or valine.
- a pharmaceutical composition for treating or preventing cancer comprising the peptide according to any one of (1) to (3).
- the pharmaceutical composition according to (4) which is in the form of a vaccine.
- An immunity-inducing agent comprising the peptide according to any one of (1) to (3).
- the immunity-inducing agent according to (7) which induces cytotoxic T cells.
- a method for producing an antigen-presenting cell having CTL-inducing activity comprising a step of contacting the peptide according to any one of (1) to (3) and an antigen-presenting cell in vitro.
- the peptide of the present invention has a high HLA binding property and a high CTL inducing ability, it is highly expected to be useful as a cancer vaccine.
- Application to various immunotherapy, especially dendritic cell therapy is also envisaged.
- Mucin is a large glycoprotein expressed in various normal and malignant epithelial cells (Devine PL and McKenzie IF: Mucins: structure, function, and associations with malignancy.Bioessays 14: 619-625, 1992.
- MUC1 is a unique glycoprotein expressed through the cell membrane on the cell surface (Gendler SJ, Lancaster CA, Taylor-Papadimitriou J, Duhig T, Peat N, Burchell J, Pemberton L, (Lalani EN and Wilson D: Molecular cloning and expression of human tumor-associated polymorphic epithelial mucin.
- MUC1 glycomodification of cancer cells is incomplete (Hanisch FG, Stadie TR, Deutzmann F and Peter-Katalinic J: MUC1 glycoforms in breast cancer-cell line T47D as a model for carcinoma-associated alterations of O-glycosylation Eur J Biochem 236: 318-327, 1996.) Induction of killer T cells against MUC1 has been reported in pancreatic cancer, breast cancer, ovarian cancer, etc.
- FIG. 1 shows an ELISA assay when a sample from a patient receiving dendritic cell / CTL therapy for MUC1 (HLA type: 24: 02/33: 03) was stimulated with the peptide of SEQ ID NO: 1, 3, 5 or 10. The results (number of IFN- ⁇ producing cells) are shown.
- FIG. 2 shows an ELISA assay when samples from patients receiving dendritic cell / CTL therapy for MUC1 (HLA type: 24: 02/33: 03) were stimulated with peptides of SEQ ID NO: 1, 3, 5 or 10 The results (number of IFN- ⁇ producing cells) are shown.
- FIG. 1 shows an ELISA assay when a sample from a patient receiving dendritic cell / CTL therapy for MUC1 (HLA type: 24: 02/33: 03) was stimulated with the peptides of SEQ ID NO: 1, 3, 5 or 10. The results (number of IFN- ⁇ producing cells) are shown.
- FIG. 1 shows an ELISA
- FIG. 3 shows an ELISA assay when a sample from a patient who received dendritic cell / CTL therapy for MUC1 (HLA type: 02: 06/24: 02) was stimulated with the peptide of SEQ ID NO: 1, 3, 5 or 10. The results (number of IFN- ⁇ producing cells) are shown.
- FIG. 4 shows that samples from patients receiving dendritic cell / CTL therapy for MUC1 (HLA type: 02: 01/02: 06) were stimulated with peptides of SEQ ID NO: 1, 2, 3, 5, 10 or 11 The results of the ELISA assay (number of IFN- ⁇ producing cells) are shown.
