Abstract

The present invention relates to peptides, proteins, 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 T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

First claim

The invention claimed is:

1. A method of treating a patient who has melanoma, wherein the cancer comprises cancer cells that overexpress the ZNF761, the ZNF765, the ZNF813, or the ZNF845 polypeptide and present at their surface in a complex with an MHC class I molecule a peptide consisting of the amino acid sequence of SEQ ID NO: 365, comprising administering to said patient a population of autologous activated cytotoxic T cells that bind the peptide consisting of the amino acid sequence of SEQ ID NO: 365 in the complex with the MHC class I molecule, and thereby target and kill the cancer cells.

2. The method of claim 1 , wherein the autologous activated cytotoxic T cells are produced by contacting T cells obtained from the patient with an antigen presenting cell that expresses the peptide in a complex with the MHC class I molecule on the surface of the antigen presenting cell, for a period of time sufficient to activate said T cells obtained from the patient.
