Non-small cell lung cancer (NSCLC) is a highly malignant tumor, with a significant mortality and morbidity. With the development of tumor immunotherapy, chimeric antigen receptor T cells (CART) gets increasingly attention and achieves prominent contributions in the treatment of hematologic malignancies. However, CART therapy for NSCLC proceeds slowly and further researches need to be investigated. In our study, we performed bioinformatics analysis to evaluate the significant role of CD147 in NSCLC. The expression level of CD147 was detected in human NSCLC cell lines and NSCLC tissues. Meanwhile, CD147-CART was constructed and identified. Cell cytotoxicity and cytokine secretion were performed to evaluate the efficacy of CD147-CART. We also constructed cell-derived xenograft (CDX) model and patient-derived xenograft (PDX) model, which was used to further investigate the safety and efficacy of CD147-CART in vivo. Our observations show that CD147 is a specific tumor antigen of NSCLC and plays an essential role in NSCLC progression, which can be used as a target for CART therapy in NSCLC. CD147-CART cells exhibit robust cytotoxicity and cytokine production in vitro, suggesting a strong anti-tumor activity against NSCLC tumor cells. Importantly, CD147-CART cells have strong anti-tumor activity against NSCLC cells in vivo in both CDX and PDX models and no adverse side effects. Our findings show that CD147-CART immunotherapy for NSCLC is safe and effective, which is an ideal and promising medical patch for treating NSCLC. |
