KEGG enrichment analysis revealed that DEGs in both the experimental and control groups were enriched in pathways related to immune disease, immune system, and infectious disease, including bacteria and parasites, including amoebiasis, hematopoietic cell lineage, asthma, African trypanosomiasis, intestinal immune network for IgA production, rheumatoid arthritis, primary immunodeficiency, and B cell receptor signaling pathway. The gene discussed is CD79A; the disease is rheumatoid arthritis.
