概括

寨卡病毒 (ZIKV) 感染会影响天生的免疫力,并导致神经损伤. 主体微RNAs (miRNAs) 显示了ZIKV诊断和治疗的潜力.

科学领域:

病毒学病毒学
分子生物学分子生物学
免疫学免疫学免疫学

背景情况:

寨卡病毒 (ZIKV) 是一个重要的重新出现的病原体,与严重的神经疾病 (如脑膜炎和先天性小头症) 有关.
目前,对于ZIKV感染,还没有有效的治疗方法.
微RNAs (miRNAs) 是细胞过程的关键调节者,它们的失调与疾病进展有关.

研究的目的:

综合审查和阐明ZIKV及其宿主之间的复杂分子相互作用.
总结当前关于分子水平上宿主-病原体相互作用的研究.

主要方法:

在感染ZIKV的人类和小鼠中分析miRNA表达特征.
确定miRNA目标及其在免疫反应和神经损伤中的作用.
对昆虫载体中miRNA参与的研究.

主要成果:

在人类中,miR-431-5p和miR-30e-5p的过度表达与先天免疫反应和神经损伤相关.
在受感染小鼠的中枢神经系统中观察到miR-124-3p目标 (例如CCL2,IL7,IRF1,SBNO2,TLR6,TNF,STAT3,NF-kB) 的升级.
降低的miR-654-3p水平与目标上调相关 (例如,FLT3LG,LITAF,CD69,TLR2).
预计昆虫中的aae-miR-286a/b-3p会向所有ZIKV基因型,并且可以转移到胚胎中.

结论:

宿主和ZIKV编码的miRNAs代表了ZIKV感染诊断的有希望的生物标志物.
这些miRNA可能为管理ZIKV感染提供潜在的治疗策略.

MicroRNAs

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
