这篇简短综述的重点是描述非编码调节 RNA,包括短 RNA (sRNA)、转移 RNA (tRNA) 片段和细胞外囊泡 (EV) 中分泌的 microRNA (miRNA),在细菌和哺乳动物(人类)宿主细胞之间的界间通讯中的作用。细菌分泌含有非编码调节RNA的囊泡,最近的研究表明,细菌囊泡与宿主细胞融合并将调节RNA递送至宿主细胞,与真核miRNA类似,调节RNA调节宿主对感染的免疫反应。最近的研究还表明,哺乳动物细胞分泌含有 miRNA 的 EV,可调节肠道微生物组、生物膜形成和细菌对抗生素的反应。因此,随着证据的积累,越来越清楚的是,细胞外囊泡中非编码调节 RNA 和 miRNA 的分泌是细菌和哺乳动物(人类)宿主细胞之间双向通讯的重要机制。然而,还需要进一步的研究来阐明细胞外囊泡中分泌的非编码调节RNA和miRNA如何介导界间通讯。
The focus of this brief review is to describe the role of noncoding regulatory RNAs, including short RNAs (sRNA), transfer RNA (tRNA) fragments and microRNAs (miRNA) secreted in extracellular vesicles (EVs), in inter-kingdom communication between bacteria and mammalian (human) host cells. Bacteria secrete vesicles that contain noncoding regulatory RNAs, and recent studies have shown that the bacterial vesicles fuse with and deliver regulatory RNAs to host cells, and similar to eukaryotic miRNAs, regulatory RNAs modulate the host immune response to infection. Recent studies have also demonstrated that mammalian cells secrete EVs containing miRNAs that regulate the gut microbiome, biofilm formation and the bacterial response to antibiotics. Thus, as evidence accumulates it is becoming clear that the secretion of noncoding regulatory RNAs and miRNAs in extracellular vesicles is an important mechanism of bidirectional communication between bacteria and mammalian (human) host cells. However, additional research is necessary to elucidate how noncoding regulatory RNAs and miRNA secreted in extracellular vesicles mediate inter-kingdom communication.
