中性粒细胞外细胞陷 (NETs) 在急性血栓事件中升高. 然而,NET标志物不能预测急性血栓事件的患者未来的心血管事件或死亡率.
科学领域:
- 心血管医学 心血管医学
- 免疫学 免疫学 免疫学
- 血液学 血液学 血液学
背景情况:
- 中性细胞外细胞陷 (NETs) 是一种新的细胞死亡机制,与血栓形成有关.
- NETs在血栓性疾病的发病过程中发挥着作用.
研究的目的:
- 研究急性血栓事件 (ATE) 患者的NETs生成.
- 为了确定NETs标记能否预测新的心血管事件.
主要方法:
- 一项病例控制研究包括患有急性冠状动脉综合征,脑血管事故和静脉血栓塞栓症的患者.
- 测量了NETs标记物 (例如MPO-DNA复合物) 和中性粒细胞激活标记物的血清水平.
- 随访评估了新的心血管事件和死亡率.
主要成果:
- 循环髓氧化酶 (MPO) -DNA复合体在ATE患者和对照人群中显著增加.
- 在对传统风险因素进行调整后,MPO-DNA复合体仍然显著.
- 在随访期间,NETs标志物没有影响生存率或新心血管事件的发生率.
结论:
- 在急性动脉和静脉血栓状况中观察到增加的NETosis标志物.
- 在ATE期间测量的当前NETs标志物不能预测未来的心血管风险或死亡率.

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...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...
