Our research confirmed that dual-targeting CAR-T (CARgpc3-egfr) cells exhibited similar proliferative ability and cytotoxicity to CARgpc3 T cells against GPC3+EGFR+ HCC in vitro...In vivo, tumor growth suppression was better for CARgpc3-egfr T cells than for CARgpc3 T cells in GPC3+EGFR+ HCC...our data indicated that dual-targeting CAR-T cells with two CARs against GPC3 and EGFR may maintain relatively effective anti-neoplasm functions in GPC3+EGFR+ HCC in vitro and in vivo, a strategy that may reduce off-tumor toxicity.
