活体显微镜技术(IVM)是指将光学显微镜应用于在完整生理条件下对活体动物组织生物学进行实时研究,具备高空间和时间分辨率。随着成像系统、遗传动物模型及成像探针等方面的进展,IVM为细胞生物学、免疫学、神经生物学和癌症研究提供了定量且动态的视角。在本综述中,我们将聚焦于纳米疗法对炎症血管的靶向作用。我们将介绍IVM的基本概念和原理,并展示IVM是一种强大的工具,可用于定量确定纳米疗法与活小鼠体内中性粒细胞或内皮细胞之间相互作用的分子机制。未来,有必要开发新的成像系统和新型成像造影剂,以便更好地理解纳米疗法在体内组织处理过程中的分子机制。
Intravital microscopy (IVM) is the application of light microscopy to real time study biology of live animal tissues in intact and physiological conditions with the high spatial and temporal resolution. Advances in imaging systems, genetic animal models and imaging probes, IVM has offered quantitative and dynamic insight into cell biology, immunology, neurobiology and cancer. In this review, we will focus on the targeting of nanotherapeutics to inflamed vasculature. We will introduce the basic concept and principle of IVM and demonstrate that IVM is a powerful tool used to quantitatively determine the molecular mechanisms of interactions between nanotherapeutics and neutrophils or endothelium in living mice. In the future, it is needed to develop new imaging systems and novel imaging contrast agents to better understand molecular mechanisms of tissue processing of nanotherapeutics in vivo.
