N6 -methyladenosine (m6A) is the most common and abundant messenger RNA modification, modulated by ‘writers’, ‘erasers’ and ‘readers’ of this mark . In vitro data have shown that m6A influences all fundamental aspects of mRNA metabolism, mainly mRNA stability, to determine stem cell fates . However, its in vivo physiological function in mammals and adult mammalian cells is still unknown. Here we show that deletion of m6A ‘writer’ protein METTL3 in mouse T cells disrupts T cell homeostasis and differentiation. In a lymphopenic mouse adoptive transfer model, naive Mettl3 deficient T cells failed to undergo homeostatic expansion and remarkably remained in the naïve state up through 12 weeks, thereby preventing colitis. Consistent with these observations, the mRNAs of SOCS family genes encoding STAT- signaling inhibitory proteins, Socs1, Socs3 and Cish, were marked by m6A, exhibited slower mRNA decay and increased mRNAs and protein expression levels in Mettl3 deficient naïve T cells. This increased SOCS family activity consequently inhibited IL-7 mediated STAT5 activation and T cell homeostatic proliferation and differentiation. We also found that m6A plays important roles for inducible degradation of Socs mRNAs in response to IL-7 signaling in order to reprogram Naïve T cells for proliferation and differentiation. Our study elucidates for the first time the in vivo biological role of m6A modification in T cell mediated pathogenesis and reveals a novel mechanism of T cell homeostasis and signal-dependent induction of mRNA degradation.
