白细胞在炎症反应中起重要作用,炎症过程的一个重要特征就是白细胞活化后黏附并穿越血管内皮细胞,向炎症部位渗出,发挥吞噬和杀伤等作用.以往认为,炎症发生时,白细胞先通过其细胞膜上的PSGL-1和血管内皮细 Leukocytes play an important role in the inflammatory response, an important feature of the inflammatory process is that leukocytes adhere to and cross the vascular endothelial cells after activation, play an active role in exudation of inflammation, phagocytosis and killing etc. In the past, leukocytes first passed PSGL-1 and vascular endothelium on the cell membrane
