细胞死亡对人类健康至关重要,并与各种严重疾病有关。因此,迫切需要产生新的细胞死亡调节剂用于疾病治疗。纳米颗粒(NPs)现在经常用于各种领域,包括消费品和医药。金纳米粒子具有稳定性好、易于修饰等优点,可用于疾病诊断和治疗。在进入人体后,GNP接触血液中的人体细胞,靶向器官和免疫系统。这种性质导致细胞功能紊乱,甚至细胞死亡。因此,GNP可以作为强大的细胞死亡调节剂。然而,目前,我们还远没有建立GNP的理化性质与细胞死亡之间的构效关系,并预测GNP诱导的细胞死亡。在这篇综述中,GNP的大小,形状和表面性质被观察到在调节各种细胞死亡方式和相关信号通路中发挥关键作用。这些结果可以指导纳米药物GNP的设计。
Cell death is crucial to human health and is related to various serious diseases. Therefore, generation of new cell death regulators is urgently needed for disease treatment. Nanoparticles (NPs) are now routinely used in a variety of fields, including consumer products and medicine. Exhibiting stability and ease of decoration, gold nanoparticles (GNPs) could be used in diagnosis and disease treatment. Upon entering the human body, GNPs contact human cells in the blood, targeting organs and the immune system. This property results in the disturbance of cell function and even cell death. Therefore, GNPs may act as powerful cell death regulators. However, at present, we are far from establishing a structure–activity relationship between the physicochemical properties of GNPs and cell death, and predicting GNP-induced cell death. In this review, GNPs’ size, shape, and surface properties are observed to play key roles in regulating various cell death modalities and related signaling pathways. These results could guide the design of GNPs for nanomedicine.
