Abstract:

Some studies have showed non-thrombolytic effects of tissue plasminogen activator (tPA) more than thrombolysis. tPA was thought to exert neurotoxicity by increasing the permeability of blood-brain barrier and accelerating neuronal death. On the other hand, both fundamental and clinical studies have showed neuroprotective effects of tPA, and its positive/negative effects on blood vessel and blood pressure. Further research focusing on the pathophysiological mechnism of tPA other than thrombolysis is necessary for its more clinical application.

Key words: Tissue plasminogen activator; Blood-brain barrier; Blood vessel; Neurotoxicity; Neuroprotection

摘要:

研究显示组织型纤溶酶原激活剂(tissue plasminogen activator,tPA)除了发挥溶栓作用外,还有一些非溶栓效应。目前认为tPA可以增加血脑屏障通透性和促进神经细胞死亡,发挥神经毒性作用。另一方面,基础和临床研究还显示tPA具有神经保护作用。此外,tPA对血管壁、血压都可能有正性或负性作用。对tPA溶栓作用外的病理生理作用的研究有助于其更好的临床应用。
