登革病毒(DENV)、日本脑炎病毒(JEV)和寨卡病毒(ZIKV)是几种重要的黄病毒,并且由这些黄病毒引起的感染仍然是世界范围的健康问题。不同的黄病毒具有不同的生物学特性和致病性。代谢组学是一个新兴的研究视角,揭示和观察某些感染的发病机制。 为了更好地了解不同黄病毒感染过程中发生的特定代谢变化,考虑到无创采样的原则,本文采用液相色谱串联质谱法对三种黄病毒感染小鼠尿样中的代谢物进行了综合分析,以更好地了解其感染机制。 与对照小鼠的尿液相比,DENV、JEV和ZIKV感染小鼠的尿液分别具有68、64和47种不同的差异代谢物。在这些代谢产物设计的代谢途径中,ABC转运蛋白、精氨酸和脯氨酸代谢以及脂解调节起着重要作用。此外,我们预测和拟合代谢产物和途径之间的潜在关系。 这些病毒特异性改变的代谢产物可能与其独特的生物学特性和致病性有关。尿液代谢组学分析对黄病毒感染的分析具有重要意义。
Dengue virus (DENV), Japanese encephalitis virus (JEV), and Zika virus (ZIKV) are several important flaviviruses, and infections caused by these flaviviruses remain worldwide health problems. Different flaviviruses exhibit different biological characteristics and pathogenicity. Metabolomics is an emerging research perspective to uncover and observe the pathogenesis of certain infections. To improve the understanding of the specific metabolic changes that occur during infection with different flaviviruses, considering the principle of noninvasive sampling, this article describes our comprehensive analysis of metabolites in urine samples from the three kinds of flavivirus-infected mice using a liquid chromatography tandem mass spectrometry method to better understand their infection mechanisms. The urine of DENV-, JEV-, and ZIKV-infected mice had 68, 64, and 47 different differential metabolites, respectively, compared with the urine of control mice. Among the metabolic pathways designed by these metabolites, ABC transporters, arginine and proline metabolism, and regulation of lipolysis play an important role. Furthermore, we predicted and fitted potential relationships between metabolites and pathways. These virus-specific altered metabolites may be associated with their unique biological properties and pathogenicity. The metabolomic analysis of urine is very important for the analysis of flavivirus infection.
