Abstract

Due to their high heterogeneity and complex tumor microenvironment, the treatment of solid tumors by CAR-T cell technology is limited. This study developed bi-specific Trop2/PD-L1 specific third-generation CAR-T cells by lentiviral infection. The specific killing ability of the bi-specific CAR-T cells against Trop2
