The KEGG enrichment analysis expanded our horizons into pathways encompassing complement and coagulation cascades, viral protein interaction with cytokine and cytokine receptor, cytokine‐cytokine receptor interaction, NF‐kappa B signalling pathway, mineral absorption, PPAR signalling pathway, pertussis, rheumatoid arthritis, IL‐17 signalling pathway and others (Figure 6D,E).These comprehensive findings underscore a profound link between the enrichment analysis and immune responses. Here, IL17A is linked to pertussis.
