CD79A and systemic lupus erythematosus: The results showed that the related signaling pathways of upregulated DEGs were mainly concentrated in the cytokine-cytokine receptor interaction, systemic lupus erythematosus, cell adhesion molecules (CAMs), intestinal immune network for IgA production, T cell receptor signaling pathways, hematopoietic cell lineage, rheumatoid arthritis (RA), graft-versus-host disease, allograft rejection, type I diabetes mellitus, autoimmune thyroid disease, and primary immunodeficiency (Fig. 4A).
