Meanwhile, we also found several immune-related pathways among them (Figure 4B), namely, complement and coagulation cascades, rheumatoid arthritis, Staphylococcus aureus infection, cytokine–cytokine receptor interaction, tuberculosis, IL-17 signaling pathway, Salmonella infection, viral protein interaction with cytokine and cytokine receptor, Fc gamma R-mediated phagocytosis, human papillomavirus infection, and vibrio cholerae infection. The gene discussed is IL17A; the disease is staphylococcus aureus infection.
