染色体间关联可以调节基因表达,但人们对这种关联的分子基础知之甚少。响应抗原刺激,幼稚 T 细胞可以分化为分别表达 IFN-γ、IL-4 和 IL-17 的 Th1、Th2 和 Th17 细胞。我们之前报道过,在幼稚 T 细胞中,IFN-γ 位点与 Th2 细胞因子位点相关。在这里,我们表明 Th2 基因座还与 IL-17 基因座相关。这种关联需要 Th2 基因座上有一个 DNase I 高敏感区 (RHS6)。 RHS6 和 IL-17 启动子均带有 Oct-1 结合位点。删除这些位点或 Oct-1 基因都会损害这种关联。 Oct-1 和 CTCF 协同结合它们的同源位点,CTCF 缺陷同样会损害这种关联。最后,关联缺陷导致 IL-17 诱导增强。总的来说,我们的数据表明 Th17 谱系分化受到 Th2 位点通过 Oct-1 和 CTCF 组织的染色体间关联的抑制。
Interchromosomal associations can regulate gene expression but little is known about the molecular basis of such associations. In response to antigen stimulation, naïve T cells can differentiate into Th1, Th2 and Th17 cells expressing IFN-γ, IL-4 and IL-17, respectively. We previously reported that in naïve T cells, the IFN-γ locus is associated with the Th2 cytokine locus. Here we show that the Th2 locus additionally associates with the IL-17 locus. This association requires a DNase I hypersensitive region (RHS6) at the Th2 locus. RHS6 and the IL-17 promoter both bear Oct-1 binding sites. Deletion of either of these sites or Oct-1 gene impairs the association. Oct-1 and CTCF bind their cognate sites cooperatively and CTCF-deficiency similarly impairs the association. Finally, defects in the association lead to enhanced IL-17 induction. Collectively, our data indicate Th17 lineage differentiation is restrained by the Th2 locus via interchromosomal associations organized by Oct-1 and CTCF.
