目前尚不清楚m6A修饰是否以及如何调节NK细胞免疫。在这里,马云等人。结果表明,NK细胞的增殖、存活和效应功能受到RNA m6A阅读器YTHDF2的正向控制。N6-甲基腺苷(M6A)是最常见的RNA转录后修饰。NK细胞是介导抗病毒和抗肿瘤免疫的主要先天淋巴样细胞。然而,m6A修饰是否以及如何影响NK细胞免疫仍不清楚。在这里,我们发现YTHDF2,一个众所周知的m6A阅读器,在NK细胞中被细胞因子、肿瘤和巨细胞病毒感染激活后上调。在体内,NK细胞Ythdf2缺乏会损害NK细胞的抗肿瘤和抗病毒活性。YTHDF2维持NK细胞的动态平衡和终末成熟,分别与调节NK细胞的转运和调节Eome有关。YTHDF2通过形成STAT5-YTHDF2正反馈环,促进NK细胞效应器功能,是IL-15介导的NK细胞存活和增殖所必需的。全转录组筛选发现TardBP在NK细胞中作为YTHDF2结合靶点参与细胞的增殖或存活。总之,我们阐明了m6A修饰在NK细胞中的生物学作用,并强调了利用NK细胞抗肿瘤免疫的新方向。
Whether and how m6A modifications regulate NK cell immunity remain unknown. Here, Ma et al. show that NK cell proliferation, survival, and effector functions are positively controlled by the RNA m6A reader YTHDF2. N6-methyladenosine (m6A) is the most prevalent posttranscriptional modification on RNA. NK cells are the predominant innate lymphoid cells that mediate antiviral and antitumor immunity. However, whether and how m6A modifications affect NK cell immunity remain unknown. Here, we discover that YTHDF2, a well-known m6A reader, is upregulated in NK cells upon activation by cytokines, tumors, and cytomegalovirus infection. Ythdf2 deficiency in NK cells impairs NK cell antitumor and antiviral activity in vivo. YTHDF2 maintains NK cell homeostasis and terminal maturation, correlating with modulating NK cell trafficking and regulating Eomes, respectively. YTHDF2 promotes NK cell effector function and is required for IL-15–mediated NK cell survival and proliferation by forming a STAT5–YTHDF2 positive feedback loop. Transcriptome-wide screening identifies Tardbp to be involved in cell proliferation or survival as a YTHDF2-binding target in NK cells. Collectively, we elucidate the biological roles of m6A modifications in NK cells and highlight a new direction to harness NK cell antitumor immunity.
