Abstract

While RNA editing by A-to-I deamination is a requisite for neuronal function in humans, it is under-investigated in single cells. Here we fill this gap by analyzing RNA editing profiles of single cells from the brain cortex of living human subjects. We show that RNA editing levels per cell are bimodally distributed and distinguish between major brain cell types, thus providing new insights into neuronal dynamics.

摘要

虽然通过A到I脱氨基作用进行的RNA编辑是人类神经元功能的必要条件,但在单细胞水平上对其研究不足。在这里,我们通过分析来自活体人类受试者大脑皮层的单细胞RNA编辑谱来填补这一空白。我们表明,每个细胞的RNA编辑水平呈双峰分布,并能区分主要的脑细胞类型,从而为神经元动力学提供了新的见解。
