纤维蛋白连结素(fibronectin,Fn)是人体血液中的冷性不溶性球蛋白,可分为血浆Fn(PFn)和细胞表面Fn(cFn)两种形式,PFn 主要来源子血管内皮细胞,是单核-巨噬细胞系统的主要调理素,在维持机体对感染的抵抗力方面有重要意义。cFn 则存在于细胞表面及多种组织中,特别是伴有上皮细胞及血管内皮细胞的基底膜上,它主要介导细胞壁糖蛋白粘附和细胞与基质的粘附,维持微血管的完整性、正常通透性及伤口修复。我们测定糖尿病血清Fn 含量,旨在探索
Fibronectin (Fn) is a cold insoluble globulin in human blood. It can be divided into plasma Fn (PFn) and cell surface Fn (cFn). PFn is mainly derived from vascular endothelial cells, - The main opsonin of the macrophage system is important in maintaining the body’s resistance to infection. cFn is found on the cell surface and in many tissues, especially the basement membrane, which is associated with epithelial cells and vascular endothelial cells. It mainly mediates cell wall glycoprotein adhesion and cell-matrix adhesion, maintains microvascular integrity, Normal permeability and wound repair. We measured the serum Fn levels in diabetes, aiming to explore
