RIGI and infection: Similarly, KEGG enrichment analysis, shown in Fig. 3i, indicated that after infection, the differential genes in DF-1 cells were mainly enriched in influenza A, herpes simplex virus 1 infection, retinoic acid-inducible gene I (RIG-I)-like receptor signaling pathway, NOD-like receptor signaling pathway, Toll-like receptor signaling pathway, alanine, aspartate and glutamate metabolism, and cytosolic DNA-sensing pathway, which were also significantly enriched after CEF infection.
