哺乳动物的免疫反应旨在根除微生物病原体,从而保护个体免受此类感染的有害影响。然而,未解决的炎症可能对宿主具有破坏性,并导致组织损伤和器官功能障碍。免疫反应甚至可以错误地靶向自身抗原并介导自身免疫性炎症。因此,各种细胞和分子机制已经发展到控制炎症反应,许多这些保障措施或触发器在自身免疫的情况下受到干扰。在这篇综述中,我们讨论了细胞非编码RNA,特别是microRNA(miRNA),在自身免疫性炎症的调节中的新作用。miRNAs如何影响炎症反应的发生、大小和消退,以及最近关于miRNAs与特定自身免疫性疾病之间联系的观察结果将被讨论。最后,将考虑参与自身免疫的miRNAs的诊断和治疗相关性。很明显,合在一起,哺乳动物miRNA是哺乳动物自身免疫性疾病发病机制的组成部分,并且可能是旨在根除组织炎症的下一代治疗剂的有效靶标。
Mammalian immune responses are intended to eradicate microbial pathogens and thus protect individuals from the harmful effects of such infections. However, unresolved inflammation can be devastating to the host and cause tissue damage and organ malfunction. Immune responses can even mistakenly target self-antigens and mediate autoimmune inflammation. Consequently, a variety of cellular and molecular mechanisms have evolved to control the inflammatory responses, and many of these safeguards or triggers are perturbed in the setting of autoimmunity. In this review, we discuss the emerging roles of cellular non-coding RNAs, and in particular microRNAs (miRNAs), in the regulation of autoimmune inflammation. How miRNAs function to impact the onset, magnitude, and resolution of inflammatory responses and recent observations regarding links between miRNAs and specific autoimmune disorders will be addressed. Finally, the diagnostic and therapeutic relevance of miRNAs involved in autoimmunity will be considered. It is clear that, taken together, mammalian miRNAs are integral to the pathogenesis of mammalian autoimmune diseases and may be effective targets of next-generation therapeutics aimed at eradicating tissue inflammation.
