外周血中性粒细胞形成高度去致密的染色质结构,称为中性粒细胞胞外陷阱(NETs),这与对细菌感染的先天免疫反应有关。中性粒细胞表达高水平的肽精氨酸脱亚胺酶4 (PAD4),它催化组蛋白瓜氨酸化。然而,PAD4或组蛋白瓜氨酸化是否在中性粒细胞染色质结构中起作用尚不清楚。在这项研究中,我们发现PAD4对组蛋白的超细化介导染色质去浓缩。在HL-60粒细胞和血液中性粒细胞高度去浓缩的染色质上检测到组蛋白超细化。抑制PAD4可减少组蛋白超细氨酸化和net样结构的形成,而PAD4处理HL-60细胞可促进这些过程。在PAD4激活后HL-60粒细胞中检测到异染色质和多小叶核结构的丢失。重要的是,生物化学定义的禽类核小体阵列的瓜氨酸化抑制了它们被连接蛋白H5压实以形成高阶染色质结构。总之,这些结果表明,组蛋白高嘌呤化在粒细胞/中性粒细胞的染色质去浓缩中具有重要作用。
Peripheral blood neutrophils form highly decondensed chromatin structures, termed neutrophil extracellular traps (NETs), that have been implicated in innate immune response to bacterial infection. Neutrophils express high levels of peptidylarginine deiminase 4 (PAD4), which catalyzes histone citrullination. However, whether PAD4 or histone citrullination plays a role in chromatin structure in neutrophils is unclear. In this study, we show that the hypercitrullination of histones by PAD4 mediates chromatin decondensation. Histone hypercitrullination is detected on highly decondensed chromatin in HL-60 granulocytes and blood neutrophils. The inhibition of PAD4 decreases histone hypercitrullination and the formation of NET-like structures, whereas PAD4 treatment of HL-60 cells facilitates these processes. The loss of heterochromatin and multilobular nuclear structures is detected in HL-60 granulocytes after PAD4 activation. Importantly, citrullination of biochemically defined avian nucleosome arrays inhibits their compaction by the linker histone H5 to form higher order chromatin structures. Together, these results suggest that histone hypercitrullination has important functions in chromatin decondensation in granulocytes/neutrophils.
