Neurons exhibit spatial compartmentalization of gene expression where localization of messenger RNAs (mRNAs) to distal processes allows for site-specific distribution of proteins through local translation. Recently, there have been reports of coordination between mRNA transport with vesicular and organellar trafficking. In this review, we will highlight the latest literature on axonal and dendritic local protein synthesis with links to mRNA-organelle cotransport followed by emerging technologies necessary to study these phenomena. Recent high-resolution imaging studies have led to insights into the dynamics of RNA-organelle interactions, and we can now peer into these intricate interactions within subcellular compartments of neurons.
神经元表现出基因表达的空间分隔,其中信使核糖核酸(mRNA)定位于远端突起,使得蛋白质能够通过局部翻译进行位点特异性分布。最近,有报道称mRNA运输与囊泡和细胞器运输之间存在协调。在这篇综述中,我们将重点介绍有关轴突和树突局部蛋白质合成的最新文献,以及与mRNA-细胞器共运输的联系,随后介绍研究这些现象所需的新兴技术。最近的高分辨率成像研究使我们对RNA-细胞器相互作用的动力学有了深入了解,现在我们可以深入观察神经元亚细胞区室内的这些复杂相互作用。
