[Abstract]  A clear understanding of nanoparticle interactions with living systems at the cellular level is necessary for developing nanoparticle-based therapeutics. Magnetic iron oxide nanoparticles provide unique opportunities to study these interactions because of their responsiveness to magnetic fields. This enables sorting of cells containing nanoparticles from in vivo models. Once sorted, flow cytometry can identify individual cell types, which can be further analyzed for iron content, gene or protein expression changes associated with nanoparticle uptake, and for other biological responses at a molecular level. Here we provide a detailed protocol to sort and identify cells in the tumor microenvironment that have internalized magnetic iron oxide nanoparticles following intravenous ... [摘要]  [摘要] 在开发基于纳米颗粒的治疗方法时,必须对纳米颗粒与生物系统在细胞水平上的相互作用有一个清晰的了解。磁性氧化铁纳米颗粒因其对磁场的响应性而提供了研究这些相互作用的独特机会。这使得能够从体内模型中筛选出包含纳米颗粒的细胞。排序后,流式细胞仪可以识别单个细胞类型,然后可以进一步分析其铁含量,与纳米颗粒摄取相关的基因或蛋白质表达变化以及分子水平的其他生物学反应。在这里,我们提供了详细的协议,用于在静脉内给药后分类和鉴定肿瘤微环境中具有内在磁性氧化铁纳米颗粒的细胞。

[背景]几种基于纳米颗粒的抗癌药物已在临床上使用,因为它们已显示出对诊断,抗癌药物传递和热疗的安全性和有效性(Marchal等,2015 ;Wu等,2015)。然而,在我们对癌症纳米医学的理解上仍然存在重大差距,主要是因为纳米颗粒与免疫细胞之间相互作用的细节仍然未知。其他人和我们已经将纳米粒子免疫细胞的相互作用确定为影响体内纳米粒子命运和在肿瘤中保留的关键变量(Sheen等人,2014;Zanganeh等人,2016; ...
