从多能祖细胞到成熟T细胞的特化效应子亚群的T细胞发育由转录因子的迭代作用引导。在每个阶段,转录因子不仅与组蛋白修饰和核小体包装的现有景观相互作用,而且它们还与其他结合因子相互作用,并以从根本上影响基因表达控制的方式修改后来到达的因子的景观。本文综述了转录因子结合的全基因组分析和由此产生的染色质构象变化的见解,揭示了细胞因子信号在效应T细胞编程中的作用,一个因素可以完全改变以前结合的因素的影响,以及在早期T细胞谱系承诺期间建立基线染色质景观的方式。
T-cell development from multipotent progenitors to specialized effector subsets of mature T cells is guided by the iterative action of transcription factors. At each stage, not only do transcription factors interact with an existing landscape of histone modifications and nucleosome packing, but they also interact with other bound factors and modify the landscape for later-arriving factors, in ways that fundamentally affect the control of gene expression. This review covers insights from genome-wide analyses of transcription factor binding and resulting chromatin conformation changes that reveal roles of cytokine signaling in effector T-cell programming, the ways one factor can completely transform the impacts of previously bound factors, and the ways that the baseline chromatin landscape is established during early T-cell lineage commitment.
