Figure 3(a) summarizes the results obtained from 20 normal controls and 292 SLE patients. Compared with normal tissue, SLE tissue generally contained a higher proportion of type 2 T helper cell, natural killer cell, and immature dendritic cell, whereas the natural killer T cell, memory B cell, and effector memory CD8 T cell were relatively lower (Figure 3(b), p < 0.05) in SLE samples. The gene discussed is CD8A; the disease is systemic lupus erythematosus.
