人ETS1缺乏会抑制几种NK细胞相关关键转录因子的表达和NK细胞的分化。

ETS1对于肿瘤细胞诱导性NK细胞毒性和IFN-γ的产生必不可少。

摘要:

自然杀伤细胞(NK)在肿瘤细胞和病原体的免疫防御中发挥重要作用,并通过细胞因子的分泌调节其他免疫细胞。虽然小鼠NK细胞的生物学已经被广泛研究,但有关转录通路调控人类NK细胞发育和成熟的知识却很有限。

通过产生ETS1缺陷的人类胚胎干细胞(hESC)和在脐血(CB)造血祖细胞(HPCs)中表达显性阴性ETS1 p27亚型,研究人员发现转录因子ETS1是人NK细胞分化的关键因子。

RNA测序结合染色质免疫沉淀(ChIP-seq)的全基因组转录组分析显示,人类ETS1可直接诱导控制NK细胞分化的关键转录因子E4BP4、TXNIP、TBET、GATA3、HOBIT和BLIMP1的表达。

此外,ETS1还调控凋亡和NK细胞活化相关基因的表达。

本研究揭示了ETS1作为人类NK细胞发育和终末分化的重要调控因子的分子机制。
