肾移植过程中免疫细胞中 NLRP1 炎症小体的激活与供体器官年龄有关吗?
炎症会导致多种疾病。在这一过程中,炎性体复合物的形成起着关键作用。虽然炎症小体在肾脏疾病中已被广泛研究,但它们在肾移植中的作用尚未完全阐明。在此,我们对接受老年或年轻供体器官的不同年龄组患者进行了肾移植前和肾移植后几个时间点的炎症小体通路几个组分的基因和蛋白表达情况进行了评估。我们的研究结果表明,在肾移植过程中,NLRP1 炎症小体在多个免疫细胞群(主要是单核细胞、CD4+ 和 CD8+ 细胞)中被激活,其水平在接受年龄较大器官的患者中逐渐升高,而在接受年龄较小器官的老年患者中则相反。尽管使用了免疫抑制剂治疗,一些患者的炎症仍然存在。这些结果提出了一个假设:供体的年龄是移植后炎症小体激活的一个关键因素,应考虑使用特异性 NLRp1 炎症小体抑制剂来提高肾移植的长期成功率。

期刊介绍: Antioxidants & Redox Signaling (ARS) is the leading peer-reviewed journal dedicated to understanding the vital impact of oxygen and oxidation-reduction (redox) processes on human health and disease. The Journal explores key issues in genetic, pharmaceutical, and nutritional redox-based therapeutics. Cutting-edge research focuses on structural biology, stem cells, regenerative medicine, epigenetics, imaging, clinical outcomes, and preventive and therapeutic nutrition, among other areas. ARS has expanded to create two unique foci within one journal: ARS Discoveries and ARS Therapeutics. ARS Discoveries (24 issues) publishes the highest-caliber breakthroughs in basic and applied research. ARS Therapeutics (12 issues) is the first publication of its kind that will help enhance the entire field of redox biology by showcasing the potential of redox sciences to change health outcomes. ARS coverage includes: -ROS/RNS as messengers -Gaseous signal transducers -Hypoxia and tissue oxygenation -microRNA -Prokaryotic systems -Lessons from plant biology
