KEGG enrichment analysis showed that the DEGs were mainly involved in hematopoietic cell lineage, Th1 and Th2 cell differentiation, Th17 cell differentiation, cell adhesion, the intestinal immune network for IgA production, allograft rejection, Staphylococcus aureus infection, graft-versus-host disease, type I diabetes mellitus, Leishmaniasis infection, autoimmune thyroid disease, B cell receptor signaling, primary immunodeficiency, T cell receptor signaling, tuberculosis, inflammatory bowel disease, natural killer cell-mediated cytotoxicity, and chemokine signaling (Figure 10H). The gene discussed is CD79A; the disease is graft versus host disease.
