  • T cell modified by chimeric antigen receptor (CAR) is considered one of the most promising tumor therapies for its almost magic effect in the treatment of hematologic malignancies. Encouraged by breakthroughs in this area, we produced Trop-2-redirected chimeric antigen receptor-modified T (Trop-2 CAR-T) cells and tested their function on ovarian cancer cells in vitro molecular cloning. Gene recombination technology was introduced to construct the Trop-2 CAR vector. The expression of Trop-2 CAR on 293T cells was tested by western blot. The effect of Trop-2 CAR-T cells on the proliferation of ovarian cancer cells was evaluated by CCK-8 assay. We found that Trop-2 CAR-T cells prominently inhibited the growth of ovarian cancer cells with Trop-2 antigen expression (P<0.05), moreover, high levels of IFN-γ and IL-2 were detected in supernatant by ELISA (P<0.01). These results suggest that Trop-2 CAR-T cells have the potential to be a clinical treatment for patients with Trop-2 positive ovarian cancer.
