纤溶酶原激活物抑制剂(Plasminogen Activator Inhibitor, PAI) 是人体内一类重要的丝氨酸蛋白酶抑制剂(Serpin),其主要功能是特异性抑制纤溶酶原激活物(如组织型纤溶酶原激活物t-PA和尿激酶型纤溶酶原激活物u-PA)的活性。纤溶系统负责溶解血栓(纤维蛋白凝块),而PAI通过抑制纤溶酶原激活物,间接抑制纤溶酶的形成,从而负向调控纤溶过程,维持凝血与纤溶系统的动态平衡。
纤溶酶原激活物抑制剂(PAI),特别是PAI-1,是纤溶系统的主要负调控因子,通过抑制t-PA和u-PA的活性来限制纤溶酶生成和纤维蛋白溶解。它在维持正常止血、防止过度出血中不可或缺,但其水平异常升高(常见于代谢性疾病和炎症状态)是血栓形成的重要机制。此外,PAI在组织纤维化和肿瘤生物学中也扮演着复杂角色。理解PAI的功能对于认识血栓性疾病、纤维化疾病和肿瘤转移的病理生理学至关重要。

Plasminogen Activator Inhibitor(PAI) 是纤溶系统中的关键调节蛋白,主要用于抑制纤溶酶原激活物(如tPA、uPA),从而调控纤维蛋白溶解过程。以下是详细解释:
PAI属于丝氨酸蛋白酶抑制剂(serpin)家族,通过结合并中和纤溶酶原激活物的活性,阻止其将纤溶酶原转化为纤溶酶。这种抑制作用在维持血液凝固和纤溶系统的动态平衡中至关重要。
PAI-1的检测常用于评估血栓倾向或纤溶功能异常。其多克隆抗体在生物学研究中用于蛋白定位、定量及机制探索。
如需进一步了解PAI的临床检测方法或疾病相关性,可参考相关生物医学数据库或研究文献。
