Abstract

Official abstract text for this publication.

The present invention relates to peptides, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated cytotoxic T cell (CTL) peptide epitopes, alone or in combination with other tumor-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses. The present invention relates to 95 novel peptide sequences and their variants derived from HLA class I molecules of human tumor cells that can be used in vaccine compositions for eliciting anti-tumor immune responses.

First claim

Opening claim text (preview).

The invention claimed is: 1. An isolated peptide comprising the amino acid sequence selected from the group consisting of SEQ ID NO: 23, SEQ ID NO: 68, SEQ ID NO: 69, and SEQ ID NO: 70, wherein the peptide is capable of inducing T cells cross-reacting with said peptide, and wherein said peptide is not a full-length polypeptide, and wherein the peptide is in the form of a pharmaceutically acceptable salt. 2. The peptide according to claim 1 having the ability to bind to a molecule of the human major histocompatibility complex (MHC) class-I or -II. 3. The peptide according to claim 1 , wherein the peptide consists essentially of the amino acid sequence selected from the group consisting of SEQ ID NO: 23, SEQ ID NO: 68, SEQ ID NO: 69, and SEQ ID NO: 70. 4. The peptide according to claim 1 , wherein the peptide is modified and/or includes non-peptide bonds. 5. The peptide according to claim 1 , wherein the peptide is a fusion protein comprising 80 N-terminal amino acids of the HLA-DR antigen-associated invariant chain (Ii) as derived from GenBank Accession Number X00497. 6. A peptide according to claim 1 for use in medicine. 7. The peptide of claim 1 , wherein said peptide having the amino acid sequence selected from the group consisting of SEQ ID NO: 23, SEQ ID NO: 68, SEQ ID NO: 69, and SEQ ID NO: 70.
