Abstract

N6-methyladenosine (m6A) is the most prevalent internal modification found in eukaryotic mRNAs and plays a critical role in shaping immune response. It acts as a dynamic regulatory step modulating the splicing, stability, degradation and translation of target mRNAs involved in regulating immune outcome. These effects are mediated by the dynamic interplay of m6A methyltransferases ("writers"), demethylases ("erasers"), and binding proteins ("readers") which work in concert to fine-tune immune activation and suppression. m6A modifications modulate both innate and adaptive immune responses by regulating chemokine signaling, inflammation, and guiding the lineage commitment and function of various cells involved in immune regulation. For example, m6A-modified mRNAs encoding interferons and pro-inflammatory cytokines are translated more efficiently, facilitating a swift response to infection, while m6A-mediated degradation of pro-inflammatory transcripts offers a counterbalance, allowing immune cells to fine-tune responses and limit overactivation. In T cells, m6A readers influence antigen responsiveness and immune tolerance, while in regulatory T cells, m6A plays a key role in maintaining immune equilibrium. In this review, we present an in-depth overview of how m6A methylation shapes immune function and outline its potential as a therapeutic target. A detailed understanding of the interplay between m6A and immune regulation may provide valuable insights for developing novel therapies for immune-related diseases.

免疫的表转录组调控:m6A在形成免疫反应动力学中的作用。
n6 -甲基腺苷(m6A)是真核生物mrna中最常见的内部修饰,在形成免疫反应中起着关键作用。它作为一个动态调控步骤,调节参与调节免疫结果的靶mrna的剪接、稳定性、降解和翻译。这些作用是由m6A甲基转移酶(“写入者”)、去甲基化酶(“擦除者”)和结合蛋白(“读取者”)的动态相互作用介导的,它们协同工作,微调免疫激活和抑制。m6A修饰通过调节趋化因子信号、炎症和指导参与免疫调节的各种细胞的谱系承诺和功能来调节先天和适应性免疫反应。例如,编码干扰素和促炎细胞因子的m6a修饰mrna被更有效地翻译,促进对感染的快速反应,而m6a介导的促炎转录物降解提供了一种平衡,允许免疫细胞微调反应并限制过度激活。在T细胞中,m6A读取器影响抗原反应性和免疫耐受,而在调节性T细胞中,m6A在维持免疫平衡中起关键作用。在这篇综述中,我们深入概述了m6A甲基化如何影响免疫功能,并概述了其作为治疗靶点的潜力。详细了解m6A与免疫调节之间的相互作用可能为开发免疫相关疾病的新疗法提供有价值的见解。

期刊介绍: The journal Cytokine has an open access mirror journal Cytokine: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. * Devoted exclusively to the study of the molecular biology, genetics, biochemistry, immunology, genome-wide association studies, pathobiology, diagnostic and clinical applications of all known interleukins, hematopoietic factors, growth factors, cytotoxins, interferons, new cytokines, and chemokines, Cytokine provides comprehensive coverage of cytokines and their mechanisms of actions, 12 times a year by publishing original high quality refereed scientific papers from prominent investigators in both the academic and industrial sectors. We will publish 3 major types of manuscripts: 1) Original manuscripts describing research results. 2) Basic and clinical reviews describing cytokine actions and regulation. 3) Short commentaries/perspectives on recently published aspects of cytokines, pathogenesis and clinical results.
