As depicted in Fig. 4B, the pathway enrichment analysis showed involvement of essential pathways like the Herpes simplex virus 1 infection, sphingolipid signaling pathway, NF-kappa B axis, Th17 cell differentiation, B cell receptor axis, Viral myocarditis, Yersinia infection, osteoclast differentiation, phospholipase D axis, and the AGE-RAGE axis. Here, PPIB is linked to viral myocarditis.
