New anticoagulation targets, factor XII and factor XI, show promise for preventing thrombosis with reduced bleeding risk. Inhibiting these factors may offer safer treatments for thromboembolic diseases.
Area of Science:
- Biochemistry
- Hematology
- Vascular Biology
Background:
- Thrombosis, a leading cause of morbidity and mortality, increases with age.
- Current anticoagulants carry a significant bleeding risk.
- Fibrin, crucial for thrombus formation, is also vital for hemostasis.
Purpose of the Study:
- To explore novel anticoagulation targets with minimal bleeding risk.
- To investigate the role of coagulation factors in thrombosis and hemostasis.
Main Methods:
- Review of experimental models in mice.
- Analysis of clinical studies on patients with factor XI or XII deficiencies.
Main Results:
- Factor XI and factor XII are critical for thrombosis.
- These factors play a minor role in hemostasis.
- Hereditary deficiencies offer protection from vascular occlusive events.
Conclusions:
- The factor XII-XI pathway is key to thrombus formation but less so to hemostasis.
- Pharmacological inhibition of factor XII or XI may lead to anticoagulation therapies with reduced bleeding risk.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
