Small-vessel vasculitis (SVV) is a chronic autoinflammatory condition linked to antineutrophil cytoplasm autoantibodies (ANCAs). Here we show that chromatin fibers, so-called neutrophil extracellular traps (NETs), are released by ANCA-stimulated neutrophils and contain the targeted autoantigens proteinase-3 (PR3) and myeloperoxidase (MPO). Deposition of NETs in inflamed kidneys and circulating MPO-DNA complexes suggest that NET formation triggers vasculitis and promotes the autoimmune response against neutrophil components in individuals with SVV.
小血管炎(SVV)是一种与抗中性粒细胞胞浆自身抗体(ANCA)相关的慢性自身炎症性疾病。我们在此表明,染色质纤维,即所谓的中性粒细胞胞外诱捕网(NETs),由ANCA刺激的中性粒细胞释放,并包含靶向自身抗原蛋白酶-3(PR3)和髓过氧化物酶(MPO)。NETs在发炎肾脏中的沉积以及循环中的MPO-DNA复合物表明,NET形成触发血管炎并促进SVV患者针对中性粒细胞成分的自身免疫反应。
