动脉血栓形成是心肌梗死、中风和四肢坏疽的直接原因。 在美国，死亡和发病的最重要原因。血小板在启动过程中起着关键作用 动脉血栓。这项SCCOR的总体目标是发现改变的基因和细胞决定因素 全身性炎症状态下的血小板功能，如动脉粥样硬化和糖尿病。我们已经集合好了 一个由临床、基础和翻译科学家组成的多学科团队，并开发了一个拥有6名科学人员的中心 项目和6个核心。项目1将使用体外分析、体内小鼠遗传模型和人类遗传 血小板膜糖蛋白CD36介导血小板高反应性这一新假说的研究 与动脉粥样硬化、糖尿病和炎症有关。项目2将探索一个至关重要的 临床问题，血小板对药物干预的耐药性，并将利用有针对性的人类基因 结合复杂的体外评估血小板功能的方法。项目3将探索 血小板活化因子(PAF)在炎症和炎症反应中的作用机制 血栓形成。项目4将研究血管内颈动脉支架置入术的临床人群 一个脆弱斑块的模型，专注于开发新的成像工具和生物标志物。项目5将 研究白细胞与血小板的相互作用，重点研究Mac-1整合素在调节血栓形成中的作用。 项目6将研究抗磷脂综合征患者，这是一种重要的自身免疫性疾病 血栓形成的原因，特别是年轻女性，以确定血栓风险的决定因素。核心A将 提供行政支持、核心B生物统计支持和核心C AN基础设施，以支持 所有6个项目的临床研究部分。核心D将提供高通量的人类基因分型 服务和核心E流式细胞仪和质谱学服务。核心F将提供一个课程和 为在SCCOR实验室接受临床血栓研究培训的医生提供职业发展支持。

Arterial thrombosis as the proximate cause of myocardial infarction, stroke, and limb gangrene remains the most important cause of mortality and morbidity in the USA. Blood platelets play a critical role in initiating arterial thrombi. The overall goal of this SCCOR is to discover genetic and cellular determinants of altered platelet function in systemic inflammatory states, such as atherosclerosis and diabetes. We have assembled a multidisciplinary team of clinical, basic and translational scientists and developed a Center with 6 scientific projects and 6 cores. Project 1 will use in vitro assays, in vivo mouse genetic models, and human genetic studies to examine the novel hypothesis that platelet glycoprotein CD36 mediates platelet hyper-reactivity associated with atherosclerosis, diabetes, and inflammation. Project 2 will explore a critically important clinical problem, platelet resistance to pharmacologic interventions, and will utilize a targeted human genetic approach coupled to sophisticated in vitro assessment of platelet function. Project 3 will explore the mechanistic role of platelet activating factor (PAF) in mediating the interface between inflammation and thrombosis. Project 4 will study a clinical population of patients undergoing endovascular carotid stenting as a model of the vulnerable plaque, focusing on developing novel imaging tools and biomarkers. Project 5 will study leukocyte-platelet interactions, focusing on the role of the Mac-1 integrin in regulating thrombosis. Project 6 will study patients with anti-phospholipid syndrome, an autoimmune disease that is an important cause of thrombosis, especially in young women, to characterize determinants of thrombotic risk. Core A will provide administrative support, Core B biostatistics support and Core C an infrastructure to support the clinical research components of all 6 projects. Core D will provide high throughput human genotyping services and Core E flow cytometry and mass spectrometry services. Core F will provide a curriculum and career development support for physicians training in clinical thrombosis research in SCCOR laboratories.
