利用纳米颗粒(NPs)进行细胞内细胞器靶向的研究正在迅速兴起。因此,针对以线粒体功能障碍为特征的疾病,如癌症、中枢神经系统疾病、心血管疾病等,利用纳米技术靶向线粒体这一细胞发动机的领域也在快速增长。优化NP靶向线粒体的能力需要对这个亚细胞细胞器中的颗粒进行量化,并从细胞中分离线粒体。目前可用的方法中使用的常规梯度离心法可能不适合于含NP的线粒体分离,因为这些颗粒在离心力的作用下经历布朗运动,产生不可重复性的结果。目前只有一种无离心法分离线粒体的方法,但这种方法需要免疫沉淀。因此,迫切需要一种可靠的离心法和无免疫沉淀法来支持基于纳米技术的线粒体靶向这一日益增长的领域。在这里,我们报道了一种线粒体靶向的磁性纳米粒子Mito-Magto,它避免了离心法和免疫沉淀法分离功能强大、呼吸活跃的纯线粒体,可用于分析和量化各种NPs的线粒体靶向性,为日益增长的线粒体纳米医学领域提供重要工具。
The field of intracellular organelle targeting using nanoparticles (NPs) is mushrooming rapidly. Thus, the area of nanotechnology-enabled targeting of mitochondrion, the cellular powerhouse, for diseases characterized by mitochondrial dysfunctions such as cancer, diseases of the central nervous system, cardiovascular diseases is also growing at a rapid pace. Optimization of NP’s ability to target the mitochondria requires quantification of the particles in this subcellular organelle and isolation of mitochondria from cells. Conventional gradient centrifugation used in currently available methods may not be appropriate for NP containing mitochondria isolation as these particles undergo Brownian motion under centrifugal forces yielding irreproducible results. There is only one method for centrifugation free mitochondria isolation, however this method requires immune-precipitation. Thus, a reliable centrifugation and immune-precipitation free method is urgently needed to support this growing field of nanotechnology-based mitochondria targeting. Here, we report a mitochondria-targeted magnetic NP, Mito-magneto, to avoid centrifugation and immune precipitation methods for isolation of functional, respiration active pure mitochondria which can be used to analyze and quantify mitochondria targeting properties of various NPs to provide an important tool for the growing field of “mitochondrial nanomedicine”.
