KEGG Pathway analysis identified many immune-related and infection pathways as differentially regulated in the microarray, including cytokine-cytokine receptor interaction, TGF-beta signaling pathway, Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway, JAK-STAT signaling pathway, chemokine signaling pathway, Wnt signaling pathway, RapI signaling pathway, measles, malaria, HTLV-1 infection, Hepatitis B, Hepatitis C, and tuberculosis (Supplementary Fig. S4). The gene discussed is SOAT1; the disease is tuberculosis.
