哺乳动物的大脑包含不同的神经元类型,但我们缺乏能够识别和表征它们的单细胞表观基因组分析。DNA甲基化是一种稳定的表观遗传标记,用于区分细胞类型和标记调控元件。我们从单个神经元细胞核中产生了超过6,000个甲基化组,并使用它们来识别额叶皮层中的16个小鼠和21个人类神经元亚群。CG和非CG甲基化表现出细胞类型特异性分布,我们确定了不同类型的神经元之间的差异甲基化调控元件。甲基化特征鉴定了第6层兴奋性神经元亚型和独特的人小清蛋白表达抑制性神经元亚型。我们观察到更强的跨物种保护的调控元件相比,兴奋性抑制神经元。单核甲基化组扩展了脑细胞类型的图谱,并确定了驱动保守脑细胞多样性的调控元件。
The mammalian brain contains diverse neuronal types, yet we lack single-cell epigenomic assays able to identify and characterize them. DNA methylation is a stable epigenetic mark that distinguishes cell types and marks regulatory elements. We generated >6,000 methylomes from single neuronal nuclei and used them to identify 16 mouse and 21 human neuronal subpopulations in the frontal cortex. CG and non-CG methylation exhibited cell type-specific distributions and we identified regulatory elements with differential methylation across neuron types. Methylation signatures identified a layer 6 excitatory neuron subtype and a unique human parvalbumin-expressing inhibitory neuron subtype. We observed stronger cross-species conservation of regulatory elements in inhibitory compared with excitatory neurons. Single-nucleus methylomes expand the atlas of brain cell types and identify regulatory elements that drive conserved brain cell diversity.
