摘要

通过联合荧光探针和超分辨率显微镜描绘复杂的线粒体动态变化在延长的时间尺度是破译线粒体相关疾病的发病机制的关键。然而,一个主要的挑战在于缺乏同时表现出强大的标记稳定性,特殊的光稳定性和最小的细胞毒性的探针。在此,合理的设计和筛选产生了一种新的共价线粒体探针,HZ Mito Red。由于其卓越的共价标记效率,HZ Mito Red表现出优越的线粒体标记稳定性,与Mito Tracker Red (MTR)相比,其稳定性提高了10倍。此外,它还表现出显著的光稳定性,在300张SIM图像后仍能保持80%以上的荧光,而光毒性可以忽略不计,即使在400张SIM图像连续成像后也能保持线粒体的完整性。这些有利的特性促进了高信噪比、长期动态SIM超分辨率成像线粒体在铁凋亡、细胞凋亡和自噬过程中的开拓,实现了线粒体形态前所未有的详细描绘。此外,专为多通道线粒体成像而设计,HZ Mito Deep Red反映了HZ Mito Red卓越的标记稳定性,在300张SIM图像后实现近光毒性的动态跟踪,具有60%的荧光保留率。值得注意的是,HZ水户红和HZ水户深红与细胞免疫荧光染色是相容的。这项研究为深入分析疾病状态下线粒体动力学提供了一个强大而通用的工具。新型共价线粒体荧光探针具有优异的标记稳定性、高光稳定性和低光毒性,可实现线粒体的长期SIM超分辨率动态成像。

Illuminating Mitochondrial Dynamics: Ultrahigh Labeling Stability Probe for Long-Term SIM Super-Resolution Imaging of Mitochondria

Delineating intricate mitochondrial dynamic changes over extended time scales through combined fluorescent probes and super-resolution microscopy is pivotal for deciphering the pathogenesis of mitochondrial-related diseases. However, a major challenge lies in the scarcity of probes that simultaneously exhibit robust labeling stability, exceptional photostability, and minimal cytotoxicity. Herein, rational design and screening yielded a novel covalent mitochondrial probe, HZ Mito Red. Due to its exceptional covalent labeling efficiency, HZ Mito Red exhibits superior mitochondrial labeling stability, with a 10-fold improvement compared to Mito Tracker Red (MTR). Furthermore, it exhibits remarkable photostability, retaining over 80% fluorescence after 300 SIM images, and negligible phototoxicity, preserving mitochondrial integrity even after 400 SIM images of continuous imaging. These advantageous properties facilitated the pioneering of high signal-to-noise, long-term dynamic SIM super-resolution imaging of mitochondria during ferroptosis, apoptosis, and autophagy, achieving unprecedented detailed delineation of mitochondrial morphology. Additionally, engineered for multichannel mitochondrial imaging, HZ Mito Deep Red mirrors the exceptional labeling stability of HZ Mito Red, achieving near-phototoxicity-free dynamic tracking with 60% fluorescence retention after 300 SIM images. Significantly, both HZ Mito Red and HZ Mito Deep Red are compatible with cell immunofluorescence staining. This study provides a robust and versatile tool for the in-depth analysis of mitochondrial dynamics in disease states.

Novel covalent mitochondrial fluorescent probes with excellent labeling stability, high photostability, and low phototoxicity allow long-term SIM super-resolution dynamic imaging of mitochondria.
