TNF and cytomegalovirus infection: The KEGG pathway enrichment analysis of these hub proteins showed they were involved in the TNF signaling pathway, the IL-17 signaling pathway, the AGE-RAGE signaling pathway in diabetic complications, Kaposi sarcoma-associated herpesvirus infection, human cytomegalovirus infection, influenza A, EGFR tyrosine kinase inhibitor resistance, the MAPK signaling pathway, the NF-kappa B signaling pathway, the Toll-like receptor signaling pathway, the C-type lectin receptor signaling pathway, and Th17 cell differentiation (Table 1).
