高血压的跨器官单细胞分析,这一成果由美国亚利桑那大学
该研究团队对血管紧张素II治疗小鼠、达尔盐敏感大鼠和自发性高血压大鼠的6个器官和组织的高血压和终末器官损伤进行了单细胞分析。该课题组人员确定了与血压和肾损伤相关的基因程序,包括保守的血管平滑肌细胞程序和跨段肾小管程序,以及组织特异性内皮适应和选择器官中细胞类型的协调变化。与人类基因组数据的整合揭示了模型特异性和共享的细胞类型-性状链接。该研究团队优先选择了一个非编码变异(rs28451064),并进行了主题基因组编辑,以证明其在体内对血压和局部基因等位基因特异性调控的影响。他们的研究为高血压研究提供了多模型、跨器官的细胞抵抗。
研究人员表示,高血压是疾病负担和死亡率的主要诱因。

Abstract: Hypertension is a leading cause of disease burden and mortality. Here, we present a single-cell analysis of hypertension and end-organ damage across six organs and tissues in angiotensin II–treated mice, Dahl salt–sensitive rats, and spontaneously hypertensive rats. We identified gene programs associated with blood pressure and renal injury, including a conserved vascular smooth muscle cell program and cross-segment renal tubular programs, along with tissue-specialized endothelial adaptations and coordinated changes across cell types in select organs. Integration with human genomic data revealed model-specific and shared cell type–trait links. We prioritized a noncoding variant (rs28451064) and used genome editing to demonstrate its in vivo effect on blood pressure and allele-specific regulation of local genes. Our study provides a multimodel, cross-organ cellular resource for hypertension research.
