Box plots showed that compared with the normal group, the levels of Plasma cells, activated CD4 memory T cells, regulatory T cells (Tregs), Monocytes, M0 Macrophages, activated Dendritic cells, and Activated Mast cells were higher in the SLE group, while the levels of Memory B cells, Resting CD4 memory T cells, Resting NK cells, and Resting Mast cells were lower (Figure 6A).
