Area of Science:

  • Biochemistry
  • Immunology
  • Hematology

Background:

  • Factor XII (FXII), or Hageman factor, is a plasma protein involved in multiple defense systems.
  • FXII participates in coagulation, fibrinolysis, kallikrein-kinin, and complement pathways.
  • FXII can be activated through surface contact or in fluid phase by various serine proteases.

Purpose of the Study:

  • To summarize the known roles of Factor XII in plasma defense systems.
  • To highlight the mechanisms of FXII activation.
  • To discuss the clinical relevance of FXII levels and the potential of FXII blockade as a therapeutic strategy.

Main Methods:

  • Review of existing literature on Factor XII activation and function.
  • Analysis of studies investigating FXII levels in various clinical conditions.

Related Experiment Videos

  • Examination of research on therapeutic interventions targeting FXII activation.

    • Main Results:

    • FXII zymogen is converted to active enzymes through distinct activation pathways.
    • Abnormal FXII plasma levels (low, undetectable, or elevated) are observed in several clinical conditions.
    • FXII plays significant roles beyond coagulation, impacting cellular functions.
    • Therapeutic blockade of FXII activation shows promise for certain clinical applications.

    Conclusions:

    • Factor XII is a key modulator of multiple plasma defense mechanisms.
    • Understanding FXII activation and its clinical implications is vital.
    • Targeting FXII activation represents a potential therapeutic avenue for various diseases.
