控制自然杀伤(NK)细胞成熟的调节机制仍然未知。在这篇文章中,Tan等人报道了Zhx 2通过控制IL-15信号传导和Zeb 2的转录作为NK细胞成熟的关键负调节因子。自然杀伤(NK)细胞的成熟和功能能力是一个严格控制的过程,依赖于转录因子(TF)。在这里,我们确定转录抑制因子锌指和同源框2(Zhx 2)作为一种新的调节器,限制NK细胞的成熟和功能。NK细胞中具有Zhx 2条件性缺失的小鼠(Zhx 2 Δ/Δ)显示成熟NK细胞的积累。Zhx 2的缺失增强了NK细胞存活和NK细胞对IL-15的应答。转录组学分析显示Zeb 2是NK细胞终末成熟的关键TF,是Zhx 2的直接下游靶标。在治疗上,Zhx 2缺陷型NK细胞的转移在不同的小鼠模型中导致肿瘤生长和转移的抑制。我们的研究结果共同揭示了Zhx 2作为NK细胞成熟中的新型负调节因子的先前未被认识的作用,并强调了其作为增强NK细胞介导的肿瘤监视的有前途的策略的治疗潜力。
The regulatory mechanisms controlling natural killer (NK) cell maturation remain unknown. In this article, Tan et al. report that Zhx2 acts as a key negative regulator of NK cell maturation by controlling IL-15 signaling and transcription of Zeb2. The maturation and functional competence of natural killer (NK) cells is a tightly controlled process that relies on transcription factors (TFs). Here, we identify transcriptional repressor zinc fingers and homeoboxes 2 (Zhx2) as a novel regulator that restricts NK cell maturation and function. Mice with Zhx2 conditional deletion in NK cells (Zhx2Δ/Δ) showed accumulation of matured NK cells. Loss of Zhx2 enhanced NK cell survival and NK cell response to IL-15. Transcriptomic analysis revealed Zeb2, a key TF in NK cell terminal maturation, as a direct downstream target of Zhx2. Therapeutically, transfer of Zhx2-deficient NK cells resulted in inhibition of tumor growth and metastasis in different murine models. Our findings collectively unmask a previously unrecognized role of Zhx2 as a novel negative regulator in NK cell maturation and highlight its therapeutic potential as a promising strategy to enhance NK cell–mediated tumor surveillance.
