细胞器大小的变化通常与其功能的改变有关。内皮细胞储存冯维勒布兰德因子 (vWF),这是一种对 Weibel-Palade 小体 (WPB) 止血至关重要的糖蛋白,Weibel-Palade 小体 (WPB) 是一种雪茄状的分泌颗粒,有多种尺寸。我们最近表明,强制改变 WPB 的大小会改变该货物的活性。我们现在发现,用他汀类药物处理的内皮细胞会产生更短的 WPB,并且它们在胞吐作用时释放的 vWF 显示出将血小板募集到内皮细胞表面的能力降低。在研究 WPB 大小变化的其他功能后果时,我们还报告说,胞吐作用时形成的内皮表面相关 vWF 会招募可溶性血浆 vWF,并且通过缩短 WPB 的治疗(包括他汀类药物)可以减少这一过程。这些结果表明,vWF在内皮表面对血小板和血浆vWF的胞吐后粘附活性反映了它们储存细胞器的大小。因此,我们的研究结果表明,通过影响其 vWF 货物的粘附活性,WPB 大小的变化可能代表了一种调节血管壁血小板聚集的新模式。
Changes in the size of cellular organelles are often linked to modifications in their function. Endothelial cells store von Willebrand Factor (vWF), a glycoprotein essential to haemostasis in Weibel-Palade bodies (WPBs), cigar-shaped secretory granules that are generated in a wide range of sizes. We recently showed that forcing changes in the size of WPBs modifies the activity of this cargo. We now find that endothelial cells treated with statins produce shorter WPBs and that the vWF they release at exocytosis displays a reduced capability to recruit platelets to the endothelial cell surface. Investigating other functional consequences of size changes of WPBs, we also report that the endothelial surface-associated vWF formed at exocytosis recruits soluble plasma vWF and that this process is reduced by treatments that shorten WPBs, statins included. These results indicate that the post-exocytic adhesive activity of vWF towards platelets and plasma vWF at the endothelial surface reflects the size of their storage organelle. Our findings therefore show that changes in WPB size, by influencing the adhesive activity of its vWF cargo, may represent a novel mode of regulation of platelet aggregation at the vascular wall.
