KEGG enrichment analysis showed that these DEGs were primarily involved in autoimmune disease and inflammatory pathways, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), autoimmune thyroid disease (AITD), graft-versus-host disease (GD), intestinal immune network for IgA production, inflammatory bowel disease, Th1 and Th2 cell differentiation, and Th17 cell differentiation. The gene discussed is CD79A; the disease is autoimmune disease.
