RESUMO
@#[Abstract] With the rapid development of nano delivery systems (NDSs) and in-depth understanding of the mechanism of cell pyroptosis, a new tumor treatment strategy formed by an ingenious combination of the two has achieved certain effects in the experimental treatment of some tumors. The strategy of inducing pyroptosis of tumor cells based on NDSs can overcome the defects of using small molecule pyroptosis inducers alone, such as fast elimination in vivo, systemic serious adverse reactions and weak tumor-targeting ability. A variety of NDSs, such as liposomes, hydrogels, polymer micelles, metal-organic frameworks (MOFs) and cell membrane biomimetic nanocarriers, have been used to construct drugs that induce tumor cell pyroptosis. On this basis, a variety of strategies based on NDSs drug-induced tumor cell have been developed, including targeting tumor stem cells, interfering with ion homeostasis, promoting ROS production, inducing epigenetic changes and delivery of gasdermin (GSDM) family proteins, etc. However, to apply these strategies clinically we still faced insufficient understanding of the interaction mechanisms between nanomaterials and biological systems. In future researches, based on a comprehensive understanding of the interaction between nanomaterials and biological systems, if we can develop new and safe NDSs, combined with effective pyroptosis inducers to target and induce tumor cell pyroptosis, so as to overcome apoptosis escape and multidrug resistance, it is expected to bring good news to tumor patients.
