抗生素耐药性的上升,加上传统研究未能发现新的抗生素,将不可避免地导致公共卫生危机,这可能会大大削弱我们对抗传染病的能力。因此,全球健康迫切需要开发针对新型细胞分子或过程的抗菌对策。RNA代表了抗菌设计的潜在靶标的一个基本上未开发的类别。几十年来,细胞行为的控制被认为是基于蛋白质的调节剂的专属权限。最近发现的小RNA(sRNA)作为一个通用的类强大的RNA为基础的调节生物分子有可能彻底改变我们的理解基因调控几乎所有的生物功能。通常,sRNA通过与多个下游靶mRNA的碱基配对来调节基因表达,以防止mRNA翻译成蛋白质。在这篇综述中,我们将讨论最近的研究,文件发现的细菌,病毒和人类的sRNAs和它们的分子机制,在调节病原体的毒力和宿主免疫。阐明sRNA在毒力和宿主免疫中的功能作用可以为开发使用sRNA作为新靶点的下一代抗生素提供基础知识。
The rise in antimicrobial drug resistance, alongside the failure of conventional research to discover new antibiotics, will inevitably lead to a public health crisis that can drastically curtail our ability to combat infectious disease. Thus, there is a great global health need for development of antimicrobial countermeasures that target novel cell molecules or processes. RNA represents a largely unexploited category of potential targets for antimicrobial design. For decades, control of cellular behavior was thought to be the exclusive purview of protein-based regulators. The recent discovery of small RNAs (sRNAs) as a universal class of powerful RNA-based regulatory biomolecules has the potential to revolutionize our understanding of gene regulation in practically all biological functions. In general, sRNAs regulate gene expression by base-pairing with multiple downstream target mRNAs to prevent translation of mRNA into protein. In this review, we will discuss recent studies that document discovery of bacterial, viral, and human sRNAs and their molecular mechanisms in regulation of pathogen virulence and host immunity. Illuminating the functional roles of sRNAs in virulence and host immunity can provide the fundamental knowledge for development of next-generation antibiotics using sRNAs as novel targets.
