Abstract

Background

Chemotherapeutic drugs, the indispensable therapy in the treatment of gastric cancer, contain many problems such as high organ toxicity and insufficient therapeutic effect. The development of nanodrug delivery carriers with both tumor targeting function and immune stimulation ability possesses the potential to remedy these practical defects.

Methods and results

In this study, a tumor targeting nanosystem that combines chemotherapy with immunotherapy was applied to the treatment and prognosis of gastric cancer. The fusion vector of iPSCs and DCs exosomes, which simultaneously possess the ability of tumor targeting and immune factor recruitment, effectively improved the in vivo efficacy of chemotherapy drugs and released the suppressed T lymphocytes under the action of modified PD-1 antibody to dredge the immunotherapy process. In addition, extensive recruitment of immune cells to clean the environment while exposing vast tumor antigens efficiently amplified the anti-tumor immune effect and ensured the good prognosis.

Conclusions

Nanodrug delivery system DOX@aiPS-DCexo could effectively inhibit the expansion process of gastric cancer MFC through synergistic chemotherapy and immunotherapy and demonstrated the capacity of improving prognosis.
