Progress in fibrinolysis.

P M Mannucci

    La Ricerca in Clinica E in Laboratorio
    |July 1, 1979
    PubMed
    Summary

    Recent advancements in fibrinolysis reveal precise plasminogen activation structures and the roles of activators and inhibitors in hemostasis. Fibrinolytic agents show promise for treating deep vein thrombosis and pulmonary embolism.

    Area of Science:

    • Biochemistry
    • Hematology
    • Molecular Biology

    Background:

    • Fibrinolysis is crucial for hemostatic balance.
    • Recent years have seen significant developments in understanding fibrinolysis.
    • Key proteins involved include plasminogen, its activators, and inhibitors.

    Purpose of the Study:

    • To review recent advancements in fibrinolysis.
    • To highlight the roles of plasminogen, its activators, and inhibitors in physiology and pathology.
    • To discuss the clinical applications of fibrinolytic agents.

    Main Methods:

    • Literature review of recent developments in fibrinolysis research.
    • Analysis of structural changes during plasminogen activation.
    • Examination of identified plasminogen activators and inhibitors.
    • Review of clinical studies on fibrinolytic therapy.

    Main Results:

    • Precise identification of structural changes in plasminogen during activation.
    • Discovery of a thrombotic tendency linked to plasminogen defects.
    • Identification of multiple plasminogen activators (tissue and vascular) with significant physiological and pathological roles.
    • Characterization of alpha 2-antiplasmin and antiactivators, revealing links between plasmin inhibitor defects and hemorrhagic tendencies, and high antiactivator levels and thrombotic conditions.

    Conclusions:

    • Understanding plasminogen activation and its regulation is key to hemostasis.
    • Defects in fibrinolytic components have clinical implications for bleeding and clotting disorders.
    • Fibrinolytic agents offer promising therapeutic options for conditions like deep vein thrombosis and pulmonary embolism.
