Targeting of mRNAs to neuronal dendrites and axons plays an integral role in intracellular signaling, development, and synaptic plasticity. Single-molecule imaging of mRNAs in neurons and brain tissue has led to enhanced understanding of mRNA dynamics. Here we discuss aspects of mRNA regulation as revealed by single-molecule detection, which has led to quantitative analyses of mRNA diversity, localization, transport, and translation. These exciting new discoveries propel our understanding of the life of an mRNA in a neuron and how its activity is regulated at the single-molecule level.
将信使核糖核酸（mRNA）靶向运输至神经元树突和轴突在细胞内信号传导、发育及突触可塑性方面发挥着不可或缺的作用。对神经元和脑组织中mRNA进行单分子成像已增进了我们对mRNA动态变化的理解。在此，我们将探讨单分子检测所揭示的mRNA调控的各个方面，这些研究成果已促成了对mRNA多样性、定位、运输及翻译的定量分析。这些令人振奋的新发现推动了我们对神经元中mRNA生命周期及其在单分子水平上的活性调控方式的理解。
