Numerous pathways closely related to immune response regulation were identified, such as cytokine-cytokine receptor interaction, complement and coagulation cascades, lysosome, intestinal immune network for IgA production, systemic lupus erythematosus, primary immunodeficiency, NF-kappa B signaling pathway, antigen processing and presentation, chemokine signaling pathway, and Toll-like receptor signaling pathway (47, 48). The gene discussed is CD79A; the disease is systemic lupus erythematosus.
