These down-regulated DEGs were closely related to non-alcoholic fatty liver disease (NAFLD), apoptosis, oxidative phosphorylation, natural killer cell-mediated cytotoxicity, human cytomegalovirus infection, Epstein–Barr virus infection, Huntington's disease, TNF signaling pathway, Chagas disease (American trypanosomiasis), aldosterone synthesis and secretion, and viral myocarditis (Figure 6D). The gene discussed is TNF; the disease is viral myocarditis.
