Kinetic analysis of the interaction between plasminogen activator inhibitor-1 and tissue-type plasminogen activator.
The kinetics of inhibition of tissue-type plasminogen activator (t-PA) by the fast-acting plasminogen activator inhibitor-1 (PAI-1) was investigated in homogeneous (plasma) and heterogeneous (solid-phase fibrin) systems by using radioisotopic and spectrophotometric analysis. It is demonstrated that fibrin-bound t-PA is protected from inhibition by PAI-1, whereas t-PA in soluble phase is rapidly...
متن کاملInteraction between Plasminogen Activator Inhibitor Type 1 ( PAI - 1 ) Bound to Fibrin and Either Tissue - type Plasminogen Activator
Plasminogen activation is catalyzed both by tissue-type(t-PA) and by urokinase-type plasminogen activator (u-PA). This reaction is controlled by plasminogen activator inhibitor type 1 (PAI-1) that is either present in plasma or bound to fibrin, present in a thrombus. We studied the mechanism of in vitro inhibition of both t-PA and u-PA activity by PAI-1 bound to fibrin. It is shown that activat...
متن کاملTissue plasminogen activator, plasminogen activator inhibitor-1, and tissue plasminogen activator/plasminogen activator inhibitor-1 complex as risk factors for the development of a first stroke.
UNLABELLED BACKGROUND NAD PURPOSE: Abnormalities in the fibrinolytic system have been associated with an increased risk for stroke in a few studies. This study was designed to test whether plasma levels of tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), and tPA/PAI-1 complex could predict a first-ever stroke. METHODS The study was an incident case-control study ...
متن کاملThe mechanism of the reaction between human plasminogen-activator inhibitor 1 and tissue plasminogen activator.
The structural events taking place during the reaction between PAI-1 (plasminogen-activator inhibitor 1) and the plasminogen activators sc-tPA (single-chain tissue plasminogen activator) and tc-tPA (two-chain tissue plasminogen activator) were studied. Complexes were formed by mixing sc-tPA or tc-tPA with PAI-1 in slight excess (on an activity basis). The complexes were purified from excess PAI...
