Abstract

Respiratory viruses have led to many deaths and hospitalizations per year in the world. The influenza virus is one of the most important respiratory viruses. Recently, metabolic studies in viral infections have been widely studied by scientists. Metabolomics states the metabolites present in a living organism under certain conditions. In this study, peripheral blood mononuclear cells were spinoculated using a virus produced by the Madin-Darby canine kidney cell culture system, and cells were harvested following spinoculation by the influenza virus. Isolation of peripheral blood mononuclear cells was performed by Ficoll-Paque density gradient centrifugation. Metabolites were extracted using organic and water approaches. Metabolic profiling was performed by a nontargeted technique using liquid chromatography with tandem mass spectrometry. Multivariate analysis methods were used to determine the main variables. the metabolic pathways involved were determined using databases. Results of the present study showed changes in biosynthesis pathways such as lipids, polyamines, catecholamines, and vitamins. Findings also showed that it is possible to explain the process of inflammation caused by the influenza virus by studying the metabolism of immune cells. © 2022 Wiley Periodicals LLC.
