Overview

Alpha2A-adrenergic receptor modulates thrombus stability in mice; leaves open whether this pathway is a viable human antithrombotic target.

Structured PICO

Does alpha(2A)-adrenergic receptor deficiency reduce thrombus stability in mouse models of thrombosis?

P
Population
Mice lacking the alpha2A-adrenergic receptor compared to wild-type mice in models of thrombosis and hemostasis.
E
Exposure
alpha(2A)-adrenergic receptor deficiency (genetic knockout)
C
Comparator
Wild-type mice
O
Outcome
Thrombus stability and embolus formation in vivo across 3 thrombosis models (pulmonary thromboembolism, FeCl3-induced mesenteric arteriole injury, mechanical aorta injury)surrogate

Main Result

Absolute Event Rate: 76% vs 100%

The alpha(2A)-adrenergic receptor plays a significant role in in vivo thrombus stabilization, as its deficiency in mice leads to increased embolization and reduced irreversible occlusion.

Cite This Study

Požgajová et al. (2006) studied Thrombosis. alpha2A-adrenergic receptor deficiency vs. Wild-type mice was evaluated on Irreversible vessel occlusion following mechanical injury. Alpha2A-adrenergic receptor deficiency in mice resulted in reduced thrombus stability, with 24% of deficient mice showing embolization and reestablished blood flow compared to 0% of wild-type mice.
