一、粘附分子的定义和由来在细胞与细胞、细胞与基质之间存在的相关多种糖蛋白，统称为细胞粘附分子。脑缺血再灌注时，参与的细胞粘附分子有3组：（）整合素组（integrinfamily）：白细胞与血管内皮细胞是否粘附取决于白细胞表面的整合素。所有的整合素的亚单位都含有CDll和CD First, the definition and origin of adhesion molecules in cells and cells, cells and matrix related to the existence of a variety of glycoproteins, collectively referred to as cell adhesion molecules. During cerebral ischemia-reperfusion, there are 3 groups of cell adhesion molecules involved: () integrinfamily: whether leukocyte and vascular endothelial cells adhere depends on the integrins on the surface of white blood cells. All integrin subunits contain CD11 and CD
