G蛋白偶联受体在血管发育中的作用

血管发育包括血管发生和血管生成两个阶段。近年研究表明, G蛋白偶联受体广泛参与调控成血管细胞的分化、迁移和接合, 尖端细胞和柄细胞命运决定, 内皮细胞的增殖、迁移和管腔形成等多个过程。文章以血管发育中的这些关键事件为主线, 总结了G蛋白偶联受体家族成员特别是视紫红质类和卷曲类受体在调节血管发育方面的最新研究进展。文章着重介绍了斑马鱼作为模式生物在血管发育生物学研究中的独特优势, 并展望了利用斑马鱼深入开展G蛋白偶联受体相关研究的广阔前景。

G protein-coupled receptors in vascular development

The vascular development consists of two continuous processes: vasculogenesis and angiogenesis. Some researches showed that G protein-coupled receptors (GPCRs) play important roles in these processes, including the regulation of differentiation, migration and coalescence of angioblasts, fate decision of tip and stalk cells, proliferation and migration of endothelial cells and tube formation. For the key events of vasculogenesis and angiogenesis, we summarize the recent advance of GPCRs, especially Class A and F. In particular, the advantages, of zebrafish, which has been widely used in developmental biology as a vertebrate model, are introduced. Using zebrafish will bring the great potential and prospect to demonstrate the role of GPCRs in vascular development in the future.
