In thymic epithelial cells, the protein Aire (autoimmune regulator) induces the ectopic expression of hundreds of peripheral tissue antigens, thus enlarging the repertoire of antigens available for the induction of central T cell tolerance. By analyzing Aire's interacting partners, Abramson et al. (2010) shed new light on this unorthodox form of gene expression.
在胸腺上皮细胞中,蛋白 Aire(自身免疫调节因子)诱导数百种外周组织抗原的异位表达,从而扩大了可用于诱导中枢 T 细胞耐受的抗原谱。通过分析 Aire 的相互作用伙伴,Abramson 等人(2010 年)为这种非传统形式的基因表达提供了新的线索。
