    • 摘要: 细胞焦亡在多种肿瘤的发生、发展过程中发挥关键作用,其诱导可通过多种机制实现。受益于纳米递送系统(NDS)的应用以及对细胞焦亡调控机制的更深入理解,产生了通过纳米载体药物递送系统诱导肿瘤细胞焦亡的新疗法,其在部分疾病的实验治疗中显示出显著疗效。多种纳米载体被用于递送诱导细胞焦亡药物,包括脂质体、水凝胶、聚合物胶束、外泌体、金属有机框架、蛋白质纳米颗粒、细胞膜仿生纳米载体、碳纳米管、树状大分子、聚合物缀合物和聚合物纳米颗粒等。利用NDS开发了一系列焦亡策略,包括干细胞靶向、离子稳态的破坏、活性氧生成的增加、表观遗传修饰的诱导以及气体蛋白Gasdermin家族蛋白的运输。这些策略的临床应用尚面临诸多挑战。本文综述了细胞焦亡的最新研究成果和NDS的应用进展,介绍了不同种类的纳米载体在递送药物过程中的应用与发展。

       

      Abstract: The phenomenon of pyroptosis has gained increasing prominence in recent decades as a significant contributor to cellular mortality. The process of pyroptosis plays a crucial role in the regulation of various types of cancers. The induction of pyroptosis can be achieved through various mechanisms, including the activation of small molecule pyrogen inducers. The use of small molecule pyrogen inducer alone, however, has limitations. On one hand, we benefit from the utilization of nano delivery systems (NDS). On the other hand, there is an enhanced comprehension of the underlying mechanism governing pyroptosis. A novel therapeutic strategy, resulting from a clever amalgamation of the two approaches, has demonstrated significant efficacy in experimental treatment of certain diseases. A variety of nanocarriers, including liposomes, hydrogels, polymer micelles, exosomes, metal-organic frameworks protein nanoparticles, cell membrane biomimetic nanocarriers, carbon nanotubes, dendrimers, polymer conjugates and polymer nanoparticles are utilized for the delivery of drugs that induce pyroptosis in cells. By integrating the aforementioned approaches, a diverse range of pyroptosis strategies have been developed utilizing NDS, encompassing stem cell targeting, disruption of ion homeostasis, augmentation of reactive oxygen species generation, induction of epigenetic modifications, and transportation of gaseous protein gasdermins family proteins. However, the clinical application of these strategies still encounters numerous challenges that need to be addressed, including limited comprehension of NDS, incomplete understanding of the interaction mechanisms between nanomaterials and biological systems, and insufficient knowledge regarding nanocarrier materials. In this study, we aim to advance the field of pyroptosis in cancer treatment. The induction of pyroptotic cell death is believed to hold great promise as an ideal therapeutic approach for the management, regulation, and treatment of numerous types of cancers.
