title: Platelet microparticles and platelet adhesion: therapeutic implications for the prevention and treatment of stroke.
abstract: Platelets are believed to play a part in all stages of the pathogenesis of ischemic stroke, from the initial formation of the atherosclerotic plaque, through plaque destabilization to the development of neuronal cell death. A process common to all of these pathogenic changes is the ability of the activated platelet to adhere to the site of disease. In addition, the release of the membrane vesicles from platelets enhances many of these processes. Therefore, an understanding of platelet adhesion and platelet microparticle release can aid the development toward the treatment and prevention of stroke. There has been much research into interventions that can reduce platelet activation in atherosclerosis and stroke. The benefits of nonpharmacologic interventions in stroke, such as diet and lifestyle modification, may in part be mediated by their effects on platelet activation. In addition, the antiplatelet drug aspirin has been shown to be useful in both the treatment of acute stroke and the secondary prevention of atherothrombosis. Other antiplatelet agents, such as the glycoprotein IIb/IIIa inhibitors and triflusal, are currently being evaluated for the treatment of acute atherothrombotic stroke.
