plasmin

Thân thiện

A scientist observes plasmin breaking down a fibrin clot in a petri dish.

Definition

1. Noun:
   • An enzyme that dissolves the fibrin of blood clots: Plasmin is a proteolytic enzyme in blood plasma that breaks down fibrin, the main protein component of blood clots, leading to clot dissolution (fibrinolysis).

Usage Examples

• Noun:
  • The activation of plasmin is a crucial step in the natural breakdown of clots.
  • Researchers are studying how plasmin activity can be regulated to treat thrombosis.

Advanced Usage

• "plasmin activation": The process by which the inactive precursor, plasminogen, is converted into the active enzyme plasmin.
  • Tissue plasminogen activator (tPA) is a drug that promotes plasmin activation to treat strokes.
• "plasmin inhibitor": A substance, such as alpha-2-antiplasmin, that naturally regulates and inhibits the activity of plasmin to prevent excessive bleeding.
  • A deficiency in plasmin inhibitor can lead to a bleeding disorder.

Variants and Related Words

• Plasminogen (n): The inactive precursor or zymogen form of plasmin, which circulates in the blood.
  • Plasminogen must be cleaved to become active plasmin.
• Fibrinolysis (n): The physiological process of breaking down blood clots, in which plasmin is the key enzyme.
  • Fibrinolysis is the body's way of removing unwanted clots.

Synonyms

• Fibrinolysin: An older, less common term for plasmin, directly referencing its function in fibrinolysis.

Related Phrases and Compounds

• Plasmin system: Refers to the complex of enzymes, inhibitors, and activators involved in the generation and regulation of plasmin activity.
  • The plasmin system is essential for maintaining vascular patency.
• Plasmin time: A laboratory test related to measuring fibrinolysis, though less common than tests like "clotting time" or "fibrinogen level."
