The scarcity of targetable proteins broadly expressed on cancer cells, but not on healthy cells, is an obstacle for chimeric antigen receptor (CAR)-T cell therapy. Here the authors establish that a functionally impaired version of P2X purinoceptor 7, non-functional P2X7 (nfP2X7), fulfils these criteria, and demonstrate that CAR-T cells targeting nfP2X7 efficiently and selectively kill breast and prostate cancer cells in mouse models.
