MicroRNAs (miRNAs) have remarkable stability and are key regulators of mRNA transcripts for several essential proteins required for the survival of cells and replication of the virus. Exosomes are thought to play an essential role in intercellular communications by transporting proteins and miRNAs, making them ideal in the search for biomarkers. Evidence suggests that miRNAs are involved in the regulation of influenza virus replication in many cell types. During the 2016 and 2017 influenza season, we collected blood samples from 54 patients infected with influenza and from 30 healthy volunteers to identify the potential role of circulating serum miRNAs and cytokines in influenza infection. Data comparing the exosomal miRNAs in patients with influenza B to healthy volunteers showed 76 miRNAs that were differentially expressed ( < 0.05). In contrast, 26 miRNAs were differentially expressed between patients with influenza A ( < 0.05) and the controls. Of these miRNAs, 11 were commonly expressed in both the influenza A and B patients. Interferon (IFN)-inducing protein 10 (IP-10), which is involved in IFN synthesis during influenza infection, showed the highest level of expression in both influenza A and B patients. Influenza A patients showed increased expression of IFNα, GM-CSF, interleukin (IL)-13, IL-17A, IL-1β, IL-6 and TNFα, while influenza B induced increased levels of EGF, G-CSF, IL-1α, MIP-1α, and TNF-β. In addition, hsa-miR-326, hsa-miR-15b-5p, hsa-miR-885, hsa-miR-122-5p, hsa-miR-133a-3p, and hsa-miR-150-5p showed high correlations to IL-6, IL-15, IL-17A, IL-1β, and monocyte chemoattractant protein-1 (MCP-1) with both strains of influenza. Next-generation sequencing studies of H1N1-infected human lung small airway epithelial cells also showed similar pattern of expression of miR-375-5p, miR-143-3p, 199a-3p, and miR-199a-5p compared to influenza A patients. In summary, this study provides insights into the miRNA profiling in both influenza A and B virus in circulation and a novel approach to identify the early infections through a combination of cytokines and miRNA expression.
微小RNA(miRNA)具有显著的稳定性,是细胞存活和病毒复制所需的几种必需蛋白质的mRNA转录本的关键调节因子。外泌体被认为通过运输蛋白质和miRNA在细胞间通讯中发挥重要作用,使其成为寻找生物标志物的理想选择。有证据表明,miRNA在多种细胞类型中参与流感病毒复制的调控。在2016年和2017年流感季节,我们收集了54例流感感染患者和30名健康志愿者的血液样本,以确定循环血清miRNA和细胞因子在流感感染中的潜在作用。比较乙型流感患者与健康志愿者外泌体miRNA的数据显示,有76种miRNA差异表达(<0.05)。相比之下,甲型流感患者与对照组之间有26种miRNA差异表达(<0.05)。在这些miRNA中,有11种在甲型和乙型流感患者中均有共同表达。在流感感染期间参与干扰素(IFN)合成的干扰素诱导蛋白10(IP-10)在甲型和乙型流感患者中均表现出最高水平的表达。甲型流感患者中IFNα、粒细胞-巨噬细胞集落刺激因子(GM-CSF)、白细胞介素(IL)-13、IL-17A、IL-1β、IL-6和肿瘤坏死因子α(TNFα)表达增加,而乙型流感则诱导表皮生长因子(EGF)、粒细胞集落刺激因子(G-CSF)、IL-1α、巨噬细胞炎性蛋白-1α(MIP-1α)和TNF-β水平升高。此外,hsa-miR-326、hsa-miR-15b-5p、hsa-miR-885、hsa-miR-122-5p、hsa-miR-133a-3p和hsa-miR-150-5p与两种流感病毒株的IL-6、IL-15、IL-17A、IL-1β和单核细胞趋化蛋白-1(MCP-1)均显示出高度相关性。对感染H1N1的人肺小气道上皮细胞进行的下一代测序研究也显示,与甲型流感患者相比,miR-375-5p、miR-143-3p、199a-3p和miR-199a-5p的表达模式相似。总之,本研究为循环中甲型和乙型流感病毒的miRNA谱提供了见解,并提供了一种通过细胞因子和miRNA表达相结合来识别早期感染的新方法。
