The mechanism underlying the autoimmune polyglandular syndrome type-1 (APS1) has been attributed to defective T-cell negative selection resulting from reduced expression and presentation of autoantigens in thymic medullary epithelial cells (MECs). It has also been postulated that Aire is involved in development of regulatory T cells, although supporting evidence is lacking. Here we show that expression of Aire in MECs is required for development of iNKT cells, suggesting a role for iNKT cells in APS1.
1型自身免疫性多腺体综合征(APS1)的潜在机制被认为是由于胸腺髓质上皮细胞(MECs)中自身抗原的表达和呈递减少导致T细胞阴性选择缺陷。也有人推测自身免疫调节因子(Aire)参与调节性T细胞的发育,尽管缺乏支持证据。在此我们表明,MECs中Aire的表达是不变自然杀伤T细胞(iNKT细胞)发育所必需的,这表明iNKT细胞在APS1中发挥作用。
