线粒体是真核生物生存所必需的。这些双膜细胞器通常形成与许多细胞结构相互作用的高度动态的管状网络。它们高度卷曲的连续内膜将细胞器分隔开,这对线粒体功能至关重要。由于线粒体小管的直径通常接近光学显微镜的衍射极限,因此使用常规光学显微镜观察亚线粒体结构或蛋白质分布通常具有挑战性(如果不是不可能的话)。这使得超分辨率显微镜在研究线粒体方面特别有价值和吸引力。超分辨率显微镜包括一套不同的方法,扩展分辨率以及纳米技术,甚至克服衍射极限。在这篇综述中,我们提供了一个概述,最近的研究使用超分辨率显微镜调查线粒体,讨论的优势和各种方法的机会,以解决线粒体生物学中的具体问题,并强调潜在的未来发展。
Mitochondria are essential for eukaryotic live. These double-membrane organelles often form highly dynamic tubular networks interacting with many cellular structures. Their highly convoluted contiguous inner membrane compartmentalizes the organelle, which is crucial for mitochondrial function. Since the diameter of the mitochondrial tubules is generally close to the diffraction limit of light microcopy, it is often challenging, if not impossible, to visualize sub-mitochondrial structures or protein distributions using conventional light microscopy. This renders super-resolution microscopy particularly valuable, and attractive, to study mitochondria. Super-resolution microscopy encompasses a diverse set of approaches that extend the resolution as well as nanoscopy techniques that even overcome the diffraction limit. In this review, we provide an overview on recent studies using super-resolution microscopy to investigate mitochondria, discuss the strengths and opportunities of the various methods to address specific questions in mitochondrial biology and highlight potential future developments.
