摘要: PROBLEM TO BE SOLVED: To provide a cell therapy method for treating tumors. SOLUTION: Artificial antigen presenting cells [AAPC; (Drosophila melanogaster)] transfected with human HLA class I and defined accessory molecules are used to stimulate CD8+T cells from both normal donors and cancer patients. The class I molecules expressed to a high density on the surface of the Drosophila cells are empty, and allow for efficient addition of a plurality of peptides that brings the generation of polyclonal responses recognizing tumor cells endogenously expressing the specific peptides. The generated responses are robust, antigen-specific and reproducible when the peptide epitope is a defined immunogen. The artificial antigen expression system can be adapted to treat most cancers in a significant majority of the population. COPYRIGHT: (C)2011,JPO&INPIT
