KEGG enrichment analysis suggested the high enrichment of various viral infection pathways and multiple immune related pathways, such as IL-17 signaling pathway, TNF signaling pathway, NF-κB signaling pathway, and JAK-STAT signaling pathway (Figure 5(d)), indicating that these pathways might be potential targets of astragalus against herpes simplex virus. The gene discussed is NFKB1; the disease is viral infectious disease.
