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。

文章导读: 本文介绍了基础和临床研究中发现的内源性和外源性组织型纤溶酶原激活剂(tissue plasminogenactivator,tPA)除了溶栓之外的神经毒性和神经保护作用及其机制,以及tPA对血管和血压的影响。

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.
