背景:P2X7离子通道是无菌性炎症的关键传感器,已被认为是肾小球肾炎的治疗靶点,P2X7拮抗纳米抗体可减轻实验性肾小球肾炎。然而,人们对 P2X7 在肾脏免疫细胞上的表达却知之甚少:方法:我们采用常规免疫荧光法对小鼠肾脏切片进行检测,同时腹腔注射纳米抗体,然后用流式细胞术分析肾实质T细胞和RNA测序,以阐明P2X7在小鼠肾实质和血管免疫细胞上的表达和功能:我们的研究表明,肾实质T细胞(包括大量自然杀伤T细胞亚群和CD69+组织驻留记忆T细胞)细胞表面的P2X7水平远高于血管T细胞。腹腔注射一次 P2X7 阻断纳米抗体后,实质 T 细胞上的 P2X7 在 30 分钟内被注射的纳米抗体完全占据。这就在细胞制备过程中有效地保护了这些细胞免受 NAD 诱导的细胞死亡。相反,全身注射模拟无菌炎症的 NAD 会导致肾实质中 P2X7hiCD69hi T 细胞的选择性耗竭:我们的研究发现了一种影响肾脏驻留 T 细胞群的新型嘌呤能调控机制。
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.
