我们对轴突内翻译的作用的认识大多来自于对轴突中少量单个mRNA的表征。然而,最近的两项研究,使用大规模的方法,以提供一个更全面的表征轴突转录组,导致发现了数千个轴突mRNA。轴突中明显丰富的mRNA增加了局部翻译比以前认为的功能更多的可能性。在这里,我们回顾了最近的研究,轴突mRNA的轮廓,并讨论如何识别轴突转录可能指向未被重视的作用,在轴突的本地翻译。
Much of our knowledge on the roles of intra-axonal translation derives from the characterization of a small number of individual mRNAs that were found to be localized in axons. However, two recent studies, using large-scale approaches to provide a more comprehensive characterization of the axonal transcriptome, have led to the discovery of thousands of axonal mRNAs. The apparent abundance of mRNAs in axons raises the possibility that local translation has many more functions than previously thought. Here, we review the recent studies that have profiled axonal mRNAs and discuss how the identification of axonal transcripts might point to unappreciated roles for local translation in axons.
