An experimental in silico study on COVID-19: Response of neutrophil-related genes to antibiotics
Abstract
BACKGROUND AND AIMS: All components of the immune system are involved in alleviating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Further research is required to provide detailed insights into COVID-19-related immune compartments and pathways. In addition, a significant percentage of hospitalized COVID-19 patients suspect bacterial infections and antimicrobial resistance occurs following antibiotics treatment. The aim of this study was to evaluate the possible effects of antibiotics on the response of neutrophil-related genes in SARS-CoV-2 patients by an experimental in silico study.
METHODS: The two data sets GSE1739 and GSE21802 including 10 SARS positive patients and 35 influenza A (H1N1) patients were analyzed, respectively. Differentially expressed genes (DEGs) between these two data sets were determined by GEO2R analysis and the Venn diagram online tool. After determining the hub genes involved in immune responses, the expression of these genes in 30 COVID-19 patients and 30 healthy individuals was analyzed by real-time polymerase chain reaction (PCR). All patients received antibiotics, including levofloxacin, colistin, meropenem, and ceftazidime.
RESULTS: GEO2R analysis detected 240 and 120 DEGs in GSE21802 and GSE1739, respectively. Twenty DEGs were considered as enriched hub genes involved in immune processes such as neutrophil degranulation, neutrophil activation, and antimicrobial humoral response. The central nodes were attributed to…
