Activation of the Coagulation Cascade as a Universal Danger Sign

Area of Science:

• Immunology
• Hematology
• Biochemistry

Background:

• Hemostasis, the process of stopping bleeding, involves clot formation.
• Inflammation and coagulation are known to activate each other.
• Emerging evidence highlights the immune functions of the hemostasis system.

Purpose of the Study:

• To review and analyze experimental and clinical data on the inflammatory function of hemostasis.
• To summarize current knowledge on immune system activation by coagulation factors.
• To re-evaluate the role of hemostasis components in immune responses.

Main Methods:

• Literature review of experimental studies.
• Analysis of clinical observation data.
• Synthesis of existing knowledge on coagulation factor-mediated immune activation.

Main Results:

• Coagulation factors are involved in activating the immune system.
• Hemostasis components function as receptors for foreign or damaged self-molecules.
• These components act as damage signals, initiating and amplifying inflammation.
• Coagulation factors influence the direction of adaptive immune responses.

Conclusions:

• The hemostasis system possesses significant immune functions.
• Coagulation factors can be classified as Damage-Associated Molecular Patterns (DAMPs).
• This reclassifies coagulation factors, challenging traditional views of the coagulation system.
