背根神经节(DRG)和三叉神经节(TG)是高度专业化的感觉神经元的细胞体簇,负责将有关我们环境的信息传递给中枢神经系统。尽管之前曾努力在分子水平上表征感觉神经元,但仍不清楚 DRG 和 TG 中存在的感觉神经元是否具有不同的表达谱,因此具有独特的分子指纹。为了解决这个问题,我们使用荧光激活细胞分选技术从 Advillin-GFP 转基因小鼠中分离出腰椎 DRG 和 TG 神经元,并进行 RNA 测序。我们的转录组分析表明,尽管非常相似,但许多基因在 DRG 和 TG 神经元中表达存在差异。重要的是,我们鉴定了 24 个在任一神经节中独特表达的基因,包括精氨酸加压素受体和几个同源框基因,为每个群体提供了独特的分子指纹。我们将我们的发现与已发表的研究进行比较,发现先前报道的存在于神经元中的许多基因实际上可能源自神经节中的其他细胞类型。此外,我们的神经元特异性结果与检查整个人类 TG 和 DRG 的数据集非常吻合。我们认为这些数据既可以提高我们对初级传入生物学的理解,也有助于开发药物治疗和基因疗法,以寻找具有独特或受限表达模式的靶点。
The dorsal root ganglia (DRG) and trigeminal ganglia (TG) are clusters of cell bodies of highly specialized sensory neurons which are responsible for relaying information about our environment to the central nervous system. Despite previous efforts to characterize sensory neurons at the molecular level, it is still unknown whether those present in DRG and TG have distinct expression profiles and therefore a unique molecular fingerprint. To address this question, we isolated lumbar DRG and TG neurons using fluorescence-activated cell sorting from Advillin-GFP transgenic mice and performed RNA sequencing. Our transcriptome analyses showed that, despite being overwhelmingly similar, a number of genes are differentially expressed in DRG and TG neurons. Importantly, we identified 24 genes which were uniquely expressed in either ganglia, including an arginine vasopressin receptor and several homeobox genes, giving each population a distinct molecular fingerprint. We compared our findings with published studies to reveal that many genes previously reported to be present in neurons are in fact likely to originate from other cell types in the ganglia. Additionally, our neuron-specific results aligned well with a dataset examining whole human TG and DRG. We propose that the data can both improve our understanding of primary afferent biology and help contribute to the development of drug treatments and gene therapies which seek targets with unique or restricted expression patterns.
