寿司(此处可能是笔误,应为SVEP1),即含血管性血友病因子A、表皮生长因子五聚素结构域蛋白1(SVEP1),是一种细胞外基质蛋白,是人类冠状动脉疾病的一个致病位点,可促进动脉粥样硬化。我们先前已证明SVEP1可诱导血管平滑肌细胞(VSMC)增殖以及动脉壁的炎症表型,从而促进动脉粥样硬化斑块的形成。已知与SVEP1相互作用的唯一受体是整合素α9β1,这是一种由血管平滑肌细胞以及髓系来源的单核细胞和巨噬细胞表达的细胞表面受体。我们先前的体外研究表明,整合素α9β1对于SVEP1诱导的血管平滑肌细胞增殖和炎症是必需的;然而,在动脉粥样硬化发展过程中,整合素α9β1在这些细胞类型中所介导的潜在机制仍知之甚少。 在此,我们利用细胞特异性基因靶向技术,在动脉粥样硬化小鼠模型中研究了整合素α9β1受体对血管平滑肌细胞和髓系细胞的影响。有趣的是,我们发现在高脂肪饮食喂养8周或16周后,无论是在血管平滑肌细胞还是髓系细胞中去除整合素α9β1,都不会影响血管中动脉粥样硬化斑块的形成或复杂性。 我们的研究结果表明,这两种细胞类型中的整合素α9β1并不介导SVEP1在动脉粥样硬化发展过程中的体内效应。相反,我们的研究结果提示,可能存在其他潜在受体,或者存在其他表达整合素α9β1的细胞类型,它们负责在动脉粥样硬化发展过程中由SVEP1诱导的信号传导。
Sushi, von Willebrand factor type A, EGF pentraxin domain-containing protein 1 (SVEP1), an extracellular matrix protein, is a human coronary artery disease locus that promotes atherosclerosis. We previously demonstrated that SVEP1 induces vascular smooth muscle cell (VSMC) proliferation and an inflammatory phenotype in the arterial wall to enhance the development of atherosclerotic plaque. The only receptor known to interact with SVEP1 is integrin α9β1, a cell surface receptor that is expressed by VSMCs and myeloid lineage-derived monocytes and macrophages. Our previous in vitro studies suggested that integrin α9β1 was necessary for SVEP1-induced VSMC proliferation and inflammation; however, the underlying mechanisms mediated by integrin α9β1 in these cell types during the development of atherosclerosis remain poorly understood. Here, using cell-specific gene targeting, we investigated the effects of the integrin α9β1 receptor on VSMCs and myeloid cells in mouse models of atherosclerosis. Interestingly, we found that depleting integrin α9β1 in either VSMCs or myeloid cells did not affect the formation or complexity of atherosclerotic plaque in vessels after either 8 or 16 weeks of high fat diet feeding. Our results indicate that integrin α9β1 in these two cell types does not mediate the in vivo effect of SVEP1 in the development of atherosclerosis. Instead, our results suggest either the presence of other potential receptor(s) or alternative integrin α9β1-expressing cell types responsible for SVEP1 induced signaling in the development of atherosclerosis.
