带有 APOL1 变异的转基因小鼠肾小球疾病的单细胞转录信号
背景:APOL1高风险变异导致非洲裔人患肾病。我们试图利用两种小鼠模型来描述细胞特异性 APOL1 变体诱导的途径:我们研究了细菌人工染色体(BAC)/APOL1 转基因小鼠与 HIV 相关肾病(HIVAN)Tg26 小鼠杂交以及 BAC/APOL1 转基因小鼠与干扰素-γ杂交的特点:结果:与 APOL1-G0 小鼠相比,APOL1-G1 小鼠的肾小球疾病都更为严重。HIVAN模型肾小球的大量RNA-seq发现了由APOL1-G1和HIV转基因激活的协同荚膜细胞损伤途径。单核 RNA-seq揭示了荚膜特异性的差异表达基因模式,这些基因是 APOL1 等位基因的一种功能。两种模型荚膜细胞中共同激活的通路(如 mTOR)和差异表达的基因(如 Ccn2)提示了 APOL1 相关肾病的新标记。HIVAN小鼠模型荚膜细胞单核RNA-seq数据显示与人类局灶节段性肾小球硬化症肾小球RNA-seq数据相似。APOL1-G1变体对真核启动因子-2通路的不同影响凸显了两种模型之间的差异:在两种小鼠模型中的这些发现表明,APOL1变体诱导的细胞类型特异性转录组特征既有共同之处,也有不同之处。这些发现为 APOL1 肾小球疾病提供了新的治疗机会。

期刊介绍: The Journal of the American Society of Nephrology (JASN) stands as the preeminent kidney journal globally, offering an exceptional synthesis of cutting-edge basic research, clinical epidemiology, meta-analysis, and relevant editorial content. Representing a comprehensive resource, JASN encompasses clinical research, editorials distilling key findings, perspectives, and timely reviews. Editorials are skillfully crafted to elucidate the essential insights of the parent article, while JASN actively encourages the submission of Letters to the Editor discussing recently published articles. The reviews featured in JASN are consistently erudite and comprehensive, providing thorough coverage of respective fields. Since its inception in July 1990, JASN has been a monthly publication. JASN publishes original research reports and editorial content across a spectrum of basic and clinical science relevant to the broad discipline of nephrology. Topics covered include renal cell biology, developmental biology of the kidney, genetics of kidney disease, cell and transport physiology, hemodynamics and vascular regulation, mechanisms of blood pressure regulation, renal immunology, kidney pathology, pathophysiology of kidney diseases, nephrolithiasis, clinical nephrology (including dialysis and transplantation), and hypertension. Furthermore, articles addressing healthcare policy and care delivery issues relevant to nephrology are warmly welcomed.
