FOLH1 and prostate neoplasm: To investigate the antitumor activity of this engineered-T cell for prostate tumors expressing prostate stem cell antigen (PSCA), prostate-specific membrane antigen (PSMA) or both antigens in vivo, they intravenously injected the dual-receptor T cell showing CAR and CCR with a specificity for PSCA and PSMA, respectively, and then tested only for the robust proliferation and tumor eradication in mice bearing the double-positive tumors.
