The aim of this study was the identification and characterization of class I HLA peptides presented on malignant hematopoietic cells in terms of their suitability for peptide-specific immunotherapies. Therefore, primary leukemia cells from eight patients were analyzed by an immunopeptidomic approach. After peptide/HLA class I immunoprecipitation and consecutive masspectrometric measurment, potential tumor antigens were identified and further validated. In conclusion, some of the identified tumor antigens might serve as targets for passive antitumor immunization approaches, especially in an allogeneic setting.
