摘要
微颗粒是多种细胞激活、损伤或凋亡时,细胞膜脱落产生的直径<1.0μm的膜性小囊泡。研究发现,微颗粒与内皮功能障碍的关系密切,在介导内皮细胞引起的炎症反应、凝血反应、内皮舒张功能减退、新生血管生成和内皮细胞凋亡等方面发挥重要作用。微颗粒与多种心血管疾病密切相关,有可能成为多种心血管疾病各个发展阶段的重要生物学指标。
Microparticles are membranous vesicles less than one micron in diameter shed from several types of cells that are activated,injured or undergoing apoptosis. Studies have found that microparticles are closely related with endothelial dysfunction. Microparticles play an important role in promoting inflammation,coagulation,endothelium-dependent vasodilation dysfunction,angiogenesis and apoptosis that are mediated by endothelial cells. Microparticles are closely related with several cardiovascular diseases and may be proved to be the true biomarkers in different stages of cardiovascular diseases.
