IFNG and Epstein-Barr virus infection: In addition, KEGG pathway and GO BP analyses revealed that the DEGs were significantly enriched in “phagosome”, “Epstein-Barr virus infection”, “viral carcinogenesis”, “proteasome”, “antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent”, “positive regulation of I-kappaB kinase/NF-kappaB signaling”, “interferon-gamma-mediated signaling pathway”, “tumor necrosis factor” and “viral process”, which were also closely associated with infection, inflammation and immunity process in the body.
