The KEGG pathways results show that the down-regulated DEGs mainly were linked with Pertussis, IL-17 signaling pathway, chemokine signaling pathway, drug metabolism-cytochrome P450, drug metabolism-cytochrome P450, Human cytomegalovirus infection, viral protein interaction with cytokine and cytokine receptor, chemical carcinogenesis-DNA adducts, Leishmaniasis, complement and coagulation cascades, Herpes simplex virus 1 infection, and steroid hormone biosynthesis. The gene discussed is IL17A; the disease is leishmaniasis.
