Abstract

Non-coding RNAs have emerged as critical regulators of the immune response to infection. MicroRNAs (miRNAs) are small non-coding RNAs which regulate host defense mechanisms against viruses, bacteria and fungi. They are involved in the delicate interplay between , the causative agent of tuberculosis (TB), and its host, which dictates the course of infection. Differential expression of miRNAs upon infection with , regulates host signaling pathways linked to inflammation, autophagy, apoptosis and polarization of macrophages. Experimental evidence suggests that virulent often utilize host miRNAs to promote pathogenicity by restricting host-mediated antibacterial signaling pathways. At the same time, host- induced miRNAs augment antibacterial processes such as autophagy, to limit bacterial proliferation. Targeting miRNAs is an emerging option for host-directed therapies. Recent studies have explored the role of long non-coding RNA (lncRNAs) in the regulation of the host response to mycobacterial infection. Among other functions, lncRNAs interact with chromatin remodelers to regulate gene expression and also function as miRNA sponges. In this review we attempt to summarize recent literature on how miRNAs and lncRNAs are differentially expressed during the course of infection, and how they influence the outcome of infection. We also discuss the potential use of non-coding RNAs as biomarkers of active and latent tuberculosis. Comprehensive understanding of the role of these non-coding RNAs is the first step towards developing RNA-based therapeutics and diagnostic tools for the treatment of TB.

摘要

非编码 RNA 已成为感染后免疫反应的关键调节因子。MicroRNAs(miRNAs)是小的非编码 RNA,可调节宿主防御机制以抵抗病毒、细菌和真菌。它们参与了结核分枝杆菌(TB)及其宿主之间微妙的相互作用,决定了感染的过程。感染 后 miRNA 的差异表达调节与炎症、自噬、细胞凋亡和巨噬细胞极化相关的宿主信号通路。实验证据表明,毒力较强的 通常利用宿主 miRNA 通过限制宿主介导的抗菌信号通路来促进致病性。同时,宿主诱导的 miRNA 增强了自噬等抗菌过程,以限制细菌增殖。针对 miRNA 是宿主定向治疗的新兴选择。最近的研究探讨了长非编码 RNA(lncRNA)在调节宿主对分枝杆菌感染反应中的作用。除其他功能外,lncRNA 与染色质重塑因子相互作用以调节基因表达,并且还作为 miRNA 海绵发挥作用。在这篇综述中,我们试图总结最近关于 miRNA 和 lncRNA 在 感染过程中如何差异表达以及它们如何影响感染结果的文献。我们还讨论了非编码 RNA 作为活动性和潜伏性结核病的生物标志物的潜在用途。全面了解这些非编码 RNA 的作用是开发基于 RNA 的治疗方法和诊断工具治疗结核病的第一步。
