The top 10 KEGG pathways were rheumatoid arthritis, hematopoietic cell lineage, Th17 cell differentiation, cytokine-cytokine receptor interaction, Th1 and Th2 cell differentiation, cell adhesion molecules (CAMs), primary immunodeficiency, viral protein interaction with cytokine and cytokine receptor, T cell receptor signaling pathway, and intestinal immune network for IgA production (Figure 3B). Here, CD79A is linked to rheumatoid arthritis.
