Visualization of Lysosomal Dynamics during Autophagy by Fluorescent Probe

is proposed for real-time monitoring of lysosomal kinetic motility. Using this probe, the dynamic process of lysosomes under starvation induction was successfully explored through fluorescence imaging. Importantly, we observed a new pattern of lysosomal dynamic movement, in which an irregular lysosome was slowly cleaved into two different-sized touching lysosomes and then fused to form a new round lysosome. This research provides a powerful fluorescence tool to understand the dynamic motility of intracellular lysosomes under fluorescence imaging.
