动脉粥样硬化病变是动脉内膜的不对称局灶性增厚,由脂质、各种细胞类型和细胞外基质(ECM)组成。这些病变导致血管闭塞,这是西方世界最常见的死亡原因。血管闭塞的主要原因是动脉粥样硬化病变破裂,随后血栓形成。纤连蛋白(FN)是最早沉积在动脉粥样硬化易感部位的ECM蛋白之一,并被认为促进动脉粥样硬化病变的形成。在这里,我们报告,动脉粥样硬化倾向载脂蛋白E-空小鼠缺乏肝细胞来源的血浆FN(pFN)喂养的促动脉粥样硬化饮食显示显着减少FN沉积在动脉粥样硬化倾向的地区,这导致显着更小,更少的动脉粥样硬化斑块。然而,pFN缺陷小鼠的动脉粥样硬化病变缺乏血管平滑肌细胞,并且未能形成纤维帽。因此,我们的研究结果表明,虽然FN通过增加致动脉粥样硬化斑块面积来延缓动脉粥样硬化的过程,但它促进了保护性纤维帽的形成,这在人体中可防止斑块破裂和血管闭塞。
Atherosclerotic lesions are asymmetric focal thickenings of the intima of arteries that consist of lipids, various cell types and extracellular matrix (ECM). These lesions lead to vascular occlusion representing the most common cause of death in the Western world. The main cause of vascular occlusion is rupture of atheromatous lesions followed by thrombus formation. Fibronectin (FN) is one of the earliest ECM proteins deposited at atherosclerosis-prone sites and was suggested to promote atherosclerotic lesion formation. Here, we report that atherosclerosis-prone apolipoprotein E-null mice lacking hepatocyte-derived plasma FN (pFN) fed with a pro-atherogenic diet display dramatically reduced FN depositions at atherosclerosis-prone areas, which results in significantly smaller and fewer atherosclerotic plaques. However, the atherosclerotic lesions from pFN-deficient mice lacked vascular smooth muscle cells and failed to develop a fibrous cap. Thus, our results demonstrate that while FN worsens the course of atherosclerosis by increasing the atherogenic plaque area, it promotes the formation of the protective fibrous cap, which in humans prevents plaques rupture and vascular occlusion.
