Out of the 74 significantly modulated KEGG pathways, the top ten pathways were the RIG-I-like receptor signalling pathway, Hepatitis B, lipid and atherosclerosis, Yersinia infection, Toll-like receptor signalling pathway, Influenza A, TNF signalling pathway, Coronavirus disease—COVID-19, NOD-like receptor signalling pathway, and cytosolic DNA-sensing pathway (Figure 2). Here, TNF is linked to COVID-19.
