The KEGG analysis revealed that NRDEGs were enriched in necroptosis, NOD-like receptor signaling pathway, TNF signaling pathway, NF-kappa B signaling pathway, influenza A, coronavirus disease-COVID-19, herpes simplex virus 1 infection, lipid and atherosclerosis, C-type lectin receptor signaling pathway, and hepatitis C (Figure 4D). Here, TNF is linked to hepatitis C virus infection.
