Checking gene expression profile associated with IRF7 and UNC93B deficient patient peripheral blood mononuclear cells infected with pH1N1 influenza virus

An innate immune defect is a defect in the innate immune response that reduces the response to infection, this can occurs in genes important for activation regulation and proliferation of the innate immune cells or pathways important for the function of innate immunity. The purpose of this study was to identify novel biomarkers of interferon Receptor 7 through bioinformatics analysis and elucidate the possible molecular mechanism. The GSE 66486 datasets containing microarray data from IRF7 and UNC93B patients and healthy controls were downloaded from the GEO database and analyzed by the GEO2R web tool to obtain different expressed genes (DEGs). Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, protein-protein interaction (PPI), and Biological Networks Gene Oncology tool (BiNGO) were then performed to elucidate the molecular mechanism of IRF7. A total of 490 DEGs were identified, of which 14 were hub genes, and involved in ribosome biogenesis, rRNA processing, gene expression, mRNA processing, nuclear lumen, intracellular non-membrane-bounded organelle, nucleoplasm, small-subunit processome, antigen processing and presentation pathway, and ribosome biogenesis in eukaryotes. Antigen processing and presentation pathway, and ribosome biogenesis in eukaryotes possibly form the basis of IRF7 or UNC93B disorders, while our study provides a list of genes and pathways that are disrupted in IRF7/UNC93B, which has the potential to be used in the clinic for diagnosis and targeted therapy of such disorders in future.
