The vectored Ebola vaccine rVSVΔG-ZEBOV-GP elicits protection against Ebola Virus Disease (EVD). In a study of forty-eight healthy adult volunteers who received either the rVSVΔG-ZEBOV-GP vaccine or placebo, we profiled intracellular microRNAs (miRNAs) from whole blood cells (WB) and circulating miRNAs from serum-derived extracellular vesicles (EV) at baseline and longitudinally following vaccination. Further, we identified early miRNA signatures associated with ZEBOV-specific IgG antibody responses at baseline and up to one year post-vaccination, and pinpointed target mRNA transcripts and pathways correlated to miRNAs whose expression was altered after vaccination by using systems biology approaches.

全球血液 miRNA 分析揭示了埃博拉疫苗 rVSVΔG-ZEBOV-GP 免疫原性的早期特征



埃博拉病毒载体疫苗 rVSVΔG-ZEBOV-GP 可预防埃博拉病毒病 (EVD)。在一项对 48 名接受 rVSVΔG-ZEBOV-GP 疫苗或安慰剂的健康成年志愿者的研究中,我们分析了来自全血细胞 (WB) 的细胞内 microRNA (miRNA) 和来自血清衍生的细胞外囊泡 (EV) 的循环 miRNA)在基线和接种疫苗后的纵向。此外,我们在基线和疫苗接种后长达 1 年内确定了与 ZEBOV 特异性 IgG 抗体反应相关的早期 miRNA 特征,并使用系统生物学方法确定了与接种疫苗后表达改变的 miRNA 相关的靶标 mRNA 转录本和通路。
