虽然多发性硬化症(MS)的病因仍然很大程度上是未知的,多线的证据表明,EB病毒(EBV)感染可能有助于MS的发展。在这里,我们的目的是确定潜在的贡献EBV编码的和宿主细胞的miRNA MS发病机制。我们鉴定了在EBV感染的B细胞(LCL)中差异表达的宿主miRNA和推定的宿主/EBV miRNA与MS风险位点的相互作用。我们估计了MS风险基因座的基因型效应对所鉴定的假定miRNA:mRNA相互作用的影响。我们发现MS风险SNP rs 4808760的保护性等位基因降低hsa-mir-3188- 3 p的表达。此外,我们的分析表明,hsa-let-7 B-5 p与ZC 3 HAV 1在LCL中的相互作用可能与B细胞不同。体外试验表明,MS风险SNP rs 10271373的保护性等位基因增加LCL中的ZC 3 HAV 1表达,但不增加B细胞中的ZC 3 HAV 1表达。LCL中保护性等位基因的更高表达与通过ZC 3 HAV 1增加的IFN应答一致,因此减少了EBV的免疫逃避。综上所述,这提供了证据表明EBV感染使B细胞miRNA机制失调,包括MS风险miRNA,其可能通过与MS风险基因直接或间接相互作用而导致MS发病。
Although the causes of Multiple Sclerosis (MS) still remain largely unknown, multiple lines of evidence suggest that Epstein–Barr virus (EBV) infection may contribute to the development of MS. Here, we aimed to identify the potential contribution of EBV-encoded and host cellular miRNAs to MS pathogenesis. We identified differentially expressed host miRNAs in EBV infected B cells (LCLs) and putative host/EBV miRNA interactions with MS risk loci. We estimated the genotype effect of MS risk loci on the identified putative miRNA:mRNA interactions in silico. We found that the protective allele of MS risk SNP rs4808760 reduces the expression of hsa-mir-3188-3p. In addition, our analysis suggests that hsa-let-7b-5p may interact with ZC3HAV1 differently in LCLs compared to B cells. In vitro assays indicated that the protective allele of MS risk SNP rs10271373 increases ZC3HAV1 expression in LCLs, but not in B cells. The higher expression for the protective allele in LCLs is consistent with increased IFN response via ZC3HAV1 and so decreased immune evasion by EBV. Taken together, this provides evidence that EBV infection dysregulates the B cell miRNA machinery, including MS risk miRNAs, which may contribute to MS pathogenesis via interaction with MS risk genes either directly or indirectly.
