抗内皮细胞抗体与系统性血管炎关系的研究进展

Relationship between AECA and systemic vasculitis

抗内皮细胞抗体(AECA)是一组与内皮细胞多种蛋白相结合的异质性自身免疫性抗体,于1971年由Lindquist和Osterland首次报道。此后越来越多的研究表明,其广泛出现在由免疫、炎症介导的血管壁损伤相关的多种自身免疫性疾病中,尤其在系统性血管炎中,具有潜在的致病作用,并且对相关自身免疫性疾病的诊断及其预后判断有一定的作用。文章就近年来对AECA及其与系统性血管炎密切相关性的研究进展作一综述。

Anti-endothelial cell antibodies （AECA） are heterogeneous autoimmune antibodies, which target at a group of antigens expressed in endothelial cells. In 1971, AECA was reported by Lindquist and Osterland for the first time. Since then, an increasing number of researches have showed that AECA exists and plays potential pathogenic role in the immune or inflammation-related diseases, especially in systemic vasculitis. AECA may be a useful sera marker for the diagnosis and prognosis judgment of related autoimmune diseases. In this review, we summarize the recent progress on the relationship betweenAECA and systemic vasculitis.
