    摘要: 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. The present invention furthermore relates to a method for producing an individualized tumour vaccine or individualized tumour therapeutic, as well as corresponding methods for treating a tumourous disease using the individualised tumour vaccine or individualised tumour therapeutic.
