冷冻电子断层扫描已经完全进入了聚光灯下。热情高涨。对我们来说幸运的是,这是一个令人兴奋的时刻,但在宣布胜利之前还有一段路要走。尽管它的潜力,冷冻电子断层扫描具有许多固有的挑战。我们如何通过厚的细胞样本,甚至可能是组织成像?我们如何在嘈杂拥挤的细胞质环境中识别感兴趣的蛋白质?我们如何针对特定时刻的动态细胞过程的断层成像?在这篇评论中,我们涵盖了冷冻电子断层扫描的历史,它是如何来的,粗略地说,以及许多方法,已开发克服其内在的局限性。文中讨论的主要冷冻EM里程碑的时间轴。每起事件的引文如下:(1)(1979):;(2)(2004):;(3)(2007):;(4)(2008):NA;(5)(2012):和;(6)(2014/VPP):;(7)(2014/cryo-PALM):;(8)(2018):;(9)(2019):;(10)(2017):。生物化学;细胞生物学;结构生物学
Cryo-electron tomography has stepped fully into the spotlight. Enthusiasm is high. Fortunately for us, this is an exciting time to be a cryotomographer, but there is still a way to go before declaring victory. Despite its potential, cryo-electron tomography possesses many inherent challenges. How do we image through thick cell samples, and possibly even tissue? How do we identify a protein of interest amidst the noisy, crowded environment of the cytoplasm? How do we target specific moments of a dynamic cellular process for tomographic imaging? In this review, we cover the history of cryo-electron tomography and how it came to be, roughly speaking, as well as the many approaches that have been developed to overcome its intrinsic limitations. Timeline of major cryo-EM milestones discussed in the text.
