    摘要:

    胆固醇流出在维持细胞正常结构和功能中发挥着关键的生理作用,然而其在调节血管新生中的作用一直未明. 近日,美国加州大学医学院的研究人员发现(Nature, 2013,498:118-122), 载脂蛋白A-I结合蛋白(apoA-I binding protein,AIBP)介导的内皮细胞胆固醇流出在调节血管新生中起着关键的作用. 研究者在小鼠离体主动脉和斑马鱼的血管新生实验中发现,AIBP和高密度脂蛋白(high density lipoprotein, HDL)协同调控胆固醇流出,抑制血管内皮生长因子(vascular endothelial growth factor,VEGF)刺激的血管新生.

    Abstract:

    Cholesterol efflux is indispensable for maintaining the structure and function of cells, while it's function in regulating angiogenesis is not clear still. Recently an issue published on Nature(2013,498:118-122) by researchers from Department of Medicine, University of California, USA found that apoA-Ⅰ binding protein (AIBP) can mediate cholesterol efflux and plays a key role in the control of angiogenesis. Based on the ex vivo aortic ring of mice and zebrafish, the researchers have found that AIBP together with HDL can facilitate cholesterol efflux so as to inhibit angiogenesis induced by vascular endothelial growth factor(VEGF).
