According to the KEGG database, the 17,512 DEGs were enriched in 67 KEGG pathways, including pathways closely related to Immunoregulation 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. Here, CD79A is linked to systemic lupus erythematosus.
