动脉粥样硬化是一种与斑块形成相关的慢性炎症性疾病,可通过血栓形成或斑块破裂转化为急性临床事件。间充质干细胞(MSC)表现出治疗各种疾病,包括动脉粥样硬化的治疗效果。本研究通过microRNA测序和生物信息学分析,发现microRNA-145(miR-145)与动脉粥样硬化相关。MSC来源的富含miR-145的exosomes可以有效地将miR-145从MSC递送至人脐静脉内皮细胞(HUVECs)。富含miR-145的外泌体的治疗可以下调JAM-A,抑制体外迁移,并减少体内动脉粥样硬化斑块。我们的研究表明,MSC衍生的富含miR-145的外泌体具有预防动脉粥样硬化的巨大潜力。
Atherosclerosis is a chronic inflammatory disease associated with the development of plaques that can be converted into an acute clinical event by thrombosis or plaque rupture. Mesenchymal stem cells (MSCs) exhibit therapeutic effects for the treatment of various diseases, including atherosclerosis. In this study, we show that microRNA-145 (miR-145) is associated with atherosclerosis by microRNA sequencing and bioinformatics analysis. MSC-derived miR-145-rich exosomes could efficiently deliver miR-145 from MSCs to human umbilical vein endothelial cells (HUVECs). Treatment of miR-145-rich exosomes could downregulate JAM-A, inhibit migration in vitro, and reduce atherosclerotic plaque in vivo. Our study suggests that MSC-derived miR-145-rich exosomes have great potential for atherosclerosis prevention.
