Abstract

Las micropartículas (MP) son un grupo heterogéneo de vesículas derivadas de la membrana plasmática de diferentes tipos de células durante la apoptosis y la activación celular, que participan en la comunicación intercelular, hemostasia, angiogénesis, reactividad vascular e inflamación. En pacientes con lupus eritematoso sistémico (LES) se ha observado incremento en algunos tipos de MP circulantes. Recientemente se ha propuesto que estas estructuras pueden participar como fuente de autoantígenos en LES.

Microparticles (MPs) are a heterogeneous group of vesicles generated from the plasma membranes of different cell types during apoptosis and cell activation. They are involved in intercellular communication, haemostasis, angiogenesis, vascular reactivity and inflammation. An increase in some types of circulating MPs has been observed in patients with systemic lupus erythematosus (SLE). It has recently been proposed that these structures may act as a source of autoantigens in SLE.

作为系统性红斑狼疮抗原底物的微粒
微颗粒(MP)是一组异质囊泡,在细胞凋亡和细胞活化过程中来自不同类型细胞的质膜,参与细胞间通讯、止血、血管生成、血管反应和炎症。在系统性红斑狼疮(sle)患者中,观察到某些类型的循环MP增加。最近有人提出,这些结构可能是sle自身抗原的来源。Microparticles (MPs) are a heterogeneous group of vesicles generated from the等离子membranes不同细胞类型during胸腺和cell activation。它们参与细胞间通信、血凝、血管生成、血管反应性和炎症。在系统性红斑狼疮(SLE)患者中观察到某些类型的循环MPs增加。然而之提议这些聘用可能act as a source of autoantigens in SLE。
