The results of the KEGG enrichment analysis of the target genes predicted by the cis-acting method revealed additional immune signaling pathways, including the B-cell receptor signaling pathway, NF-kappa B signaling pathway, FoxO signaling pathway, Epstein–Barr virus infection, viral myocarditis, chemokine signaling pathway, and MAPK signaling pathway. Here, PPIB is linked to viral myocarditis.
