Purpose: Chimeric antigen receptor (CAR)-T cells have shown to play a vital role in antitumor functions in hematological malignancies, but have poor efficacy in solid tumors. To improve the activation and proliferation of CAR-T cell in solid tumors, we constructed an enhanced CAR-T cells to increase the survival of esophageal cancer. Materials and Methods: To construct enhanced CAR-T cells, we chose MUC1 as the target of CAR-T cells. Long-term co-culture of target cells and effector cells was applied to verify the antitumor activity of these enhanced MUC1-CAR-T cells in vitro. Moreover, a mouse xenograft model was established to investigate the effects of enhanced MUC1-CAR-T cells on tumor elimination in vivo. Results: In vitro studies showed that enhanced MUC1-CAR-T cells have long-lasting tumor killing and proliferative capabilities. Moreover, animal experiments verified that enhanced MUC1-CAR-T cells had significant antitumor function and a prolonged half-life by subcutaneous transplantation models of esophageal cancer and PDX models of esophageal cancer, in vivo. Conclusion: These results indicated that enhanced MUC1-CAR-T cells have a significant cytotoxic effect on esophageal cancer, and may likely to provide a novel strategy for the treatment of esophageal cancer.
