活体成像正变得越来越流行,并被用于可视化细胞运动和功能。与类似于体内分析的体外分析相反,活体成像可用于直接在体内观察和分析细胞。在这篇综述中,我将总结最近的影像学研究自体反应性T细胞浸润到中枢神经系统(CNS),并提供技术背景。在它们的体内旅程中,自身反应性T细胞与许多不同的细胞相互作用。首先,自身反应性T细胞与肺气道中的内皮细胞或脾细胞相互作用,在那里它们获得迁移表型以渗透到中枢神经系统中。到达CNS后,它们在穿过血脑屏障之前与软脑膜血管或脉络丛的内皮细胞相互作用。CNS浸润性T细胞通过识别由局部抗原呈递细胞(APC)呈递的内源性自身抗原而被激活。通过使用基于蛋白质的传感器在体内可视化这种激活。一种这样的传感器检测细胞内钙浓度的变化作为T细胞活化的早期标志。另一种传感器检测活化T细胞的核因子(NFAT)从胞质溶胶到细胞核的易位,作为T细胞活化的确定性标志。重要的是,活体成像不仅仅用于可视化细胞行为。结合精确的分析,活体成像加深了我们对活体器官中细胞功能的了解,并为开发治疗性治疗提供了平台。
Intravital imaging is becoming more popular and is being used to visualize cellular motility and functions. In contrast to in vitro analysis, which resembles in vivo analysis, intravital imaging can be used to observe and analyze cells directly in vivo. In this review, I will summarize recent imaging studies of autoreactive T cell infiltration into the central nervous system (CNS) and provide technical background. During their in vivo journey, autoreactive T cells interact with many different cells. At first, autoreactive T cells interact with endothelial cells in the airways of the lung or with splenocytes, where they acquire a migratory phenotype to infiltrate into the CNS. After arriving at the CNS, they interact with endothelial cells of the leptomeningeal vessels or the choroid plexus before passing through the bloodebrain barrier. CNS-infiltrating T cells become activated by recognizing endogenous autoantigens presented by local antigen-presenting cells (APCs). This activation was visualized in vivo by using protein-based sensors. One such sensor detects changes in intracellular calcium concentration as an early marker of T cell activation. Another sensor detects translocation of Nuclear factor of activated T-cells (NFAT) from cytosol to nucleus as a definitive sign of T cell activation. Importantly, intravital imaging is not just used to visualize cellular behavior. Together with precise analysis, intravital imaging deepens our knowledge of cellular functions in living organs and also provides a platform for developing therapeutic treatments.
