microRNA(miRNAs)是一类保守的非编码RNA分子,通过靶向特定信使RNA(mRNAs)的3′非翻译区(UTR)进行降解或翻译抑制,从而在转录后调控基因表达。miRNA介导的基因调控对于正常细胞功能如细胞周期、分化和凋亡至关重要,并且多达三分之一的人类mRNA可能是miRNA靶点。越来越多的证据表明,miRNAs在调节免疫功能和预防自身免疫中发挥着重要作用。本文综述了近年来发现的miRNA在免疫功能调节、自身免疫和自身免疫性疾病发生发展中的作用。具体而言,我们讨论了参与的先天性和适应性免疫反应,免疫细胞的发展,调节性T细胞的稳定性和功能,以及类风湿性关节炎和系统性红斑狼疮的差异miRNA表达的miRNA调控。
MicroRNAs (miRNAs) are small conserved non-coding RNA molecules that post-transcriptionally regulate gene expression by targeting the 3′ untranslated region (UTR) of specific messenger RNAs (mRNAs) for degradation or translational repression. miRNA-mediated gene regulation is critical for normal cellular functions such as the cell cycle, differentiation, and apoptosis, and as much as one-third of human mRNAs may be miRNA targets. Emerging evidence has demonstrated that miRNAs play a vital role in the regulation of immunological functions and the prevention of autoimmunity. Here we review the many newly discovered roles of miRNA regulation in immune functions and in the development of autoimmunity and autoimmune disease. Specifically, we discuss the involvement of miRNA regulation in innate and adaptive immune responses, immune cell development, T regulatory cell stability and function, and differential miRNA expression in rheumatoid arthritis and systemic lupus erythematosus.
