Abstract: The present invention relates to novel tumor-associated antigens, which elicit independently from a presentation via MHC a CD8-positive T-cell response. GM-CSF-Receptor alpha chain (CSF2RA) and Tyrosinase-related protein 2 (TRP-2) were found to be targets of CD8-positive T-cell clones which could detect the proteins on the surface of HLA I negative melanoma cells. Thus, the invention provides proteins, protein fragments and polypeptides of the novel antigens for use in medicine, for example for the treatment, diagnosis and prevention of a tumor disease. Furthermore provided are nucleic acids expressing the antigens of the invention, binding agents specific for the antigens of the invention, such as T-cell receptor chains and isolated T cells which are reactive against the antigens of the invention or which express the T-cell receptors of the invention.

Abstract: The present invention relates to certain melanoma-associated oligopeptides that are recognized by CD8-positive cytotoxic T-lymphocytes (CTLs) as peptide antigen and which elicit a CTL-induced lysis and/or apoptosis of tumor cells. The present invention also relates to the use of these melanoma-associated oligopeptides in cancer therapy.

Abstract: The present invention relates to a method for identifying the preferential target antigens of antitumoural T-cells of a tumour patient, comprising: a) providing T-cells from the blood of at least one tumour patient, b) providing dendritic cell (DCs) and/or B-lymphocytes (BLCs) that are autologous for said tumour patient, wherein said DCs and BLCs were transfected beforehand with a selection of mRNAs encoding for T-cell-immunogenic tumour-associated antigens (TAA), and express these, c) contacting said T-cells with the DCs and/or BLCs, d) identifying of those T-cells that recognize antigens of the DCs and/or BLCs, and e) identifying of the preferential target antigens of antitumoural T-cells of the at least one tumour patient on the basis of the T-cells that recognize antigens of the DCs and/or BLCs. The method can furthermore comprise the expansion of the T-cells that recognize the antigens of the DCs and/or BLCs.

Abstract: The invention relates to nucleic acid molecules coding for a tumor rejection antigen precursor. Specifically, the tumor rejection antigen precursor, or ‘TRAP”, is processed into at least one tumor rejection antigen, which is presented by HLA-A2 molecules. Ramifications of the discovery are also set forth.
