概述

纤纤溶酶是一种丝氨酸蛋白酶,在纤溶过程中对血凝块的降解起核心作用,可降解血凝块的主要结构组分纤维蛋白。除纤溶这一主要功能外,纤溶酶还参与纤维蛋白原溶解、补体激活、组织重塑及炎症反应。纤溶酶在肝脏中以无活性前体纤溶酶原的形式合成,纤溶酶原于血液中循环,在血栓形成部位可被组织型纤溶酶原激活剂(tPA)、尿激酶激活;临床中也可通过链激酶实现激活。结构上,纤溶酶含有多个结构域,其中包括kringle(三环)结构域,该结构域可介导与纤维蛋白及细胞表面赖氨酸残基的结合,提升蛋白靶向能力与酶活性。

常见科研用途:

功能层面,纤溶酶除溶解血凝块外,还可激活胶原酶、补体组分(如 C1、C5),切割细胞外基质蛋白,参与胚胎发育、伤口愈合、肿瘤侵袭等生理病理过程。纤溶酶活性不足或调控异常,会引发血栓形成,也可导致纤溶酶原缺乏症这类罕见疾病,造成伤口愈合与组织修复障碍。在临床领域,纤溶酶及其激活剂作为溶栓药物,用于心肌梗死、脑卒中、肺栓塞等病症的治疗;现有研究正在开发基因工程改造的纤溶酶变体,以期获得更安全、靶向性更强的治疗制剂。

常见应用:体外诊断(IVD)检测标准品、校准品与质控品,凝血研究,心血管研究,治疗药物开发。

Plasmin is a serine protease central to the breakdown of blood clots through fibrinolysis, where it degrades fibrin, the main structural component of clots. Beyond its primary role in fibrinolysis, plasmin also participates in fibrinogenolysis, complement activation, tissue remodeling, and inflammation. It is synthesized in the liver as the inactive precursor plasminogen, which circulates in the blood and is activated at sites of clot formation by tissue plasminogen activator (tPA), urokinase, or therapeutically by streptokinase. Structurally, plasmin contains multiple domains, including kringle domains that facilitate binding to lysine residues on fibrin and cell surfaces, enhancing its targeting and activity.
Common research uses
Functionally, plasmin not only dissolves clots but also activates collagenases, complement components (such as C1 and C5), and cleaves extracellular matrix proteins, contributing to processes like embryonic development, wound healing, and tumor invasion. Deficiencies or dysregulation of plasmin activity can lead to thrombosis or rare disorders such as plasminogen deficiency, which impairs wound healing and tissue repair. Clinically, plasmin and its activators are used as thrombolytic agents to treat conditions like myocardial infarction, stroke, and pulmonary embolism, and ongoing research explores engineered plasmin variants for safer, more targeted therapies.
Common uses include IVD Assay standards, calibrators and controls, coagulation research, cardiovascular research, therapeutics development.

生化机理
Plasmin dissolves the fibrin of blood clots and acts as a proteolytic factor in a variety of other processes including embryonic development, tissue remodeling, tumor invasion, and inflammation. In ovulation, weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1, C4 and C5. Cleavage of fibronectin and laminin leads to cell detachment and apoptosis. Also cleaves fibrin, thrombospondin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4.
