先天免疫系统的一个标志是其以依赖于动态染色质状态的细胞和病原体特异性方式快速启动短暂或持续转录程序的能力。大部分表观遗传景观是在细胞分化过程中设定的;然而,病原体和其他环境因素也会诱导染色质的变化,这些变化可以促进耐受性或“训练”先天免疫细胞以放大次级反应。我们审查染色质的过程,使先天免疫细胞分化和功能性转录反应在幼稚或经验丰富的细胞,与信号转导和细胞代谢的变化。我们讨论了免疫染色质机制是如何在疾病和细胞重编程的新的治疗方法不适应。
A hallmark of the innate immune system is its ability to rapidly initiate short-lived or sustained transcriptional programs in a cell- and pathogen-specific manner that is dependent on dynamic chromatin states. Much of the epigenetic landscape is set during cellular differentiation; however, pathogens and other environmental cues also induce changes in chromatin that can either promote tolerance or ‘train’ innate immune cells for amplified secondary responses. We review chromatin processes that enable innate immune cell differentiation and functional transcriptional responses in naive or experienced cells, in concert with signal transduction and cellular metabolic shifts. We discuss how immune chromatin mechanisms are maladapted in disease and novel therapeutic approaches for cellular reprogramming.
