SLE (n = 3) immature FLDCs expressed higher CCR7 than normal (n = 3) immature FLDCs. (a) Mature FLDCs from both SLE patients and normal controls expressed higher-level of CCR7 than immature FLDCs. Immature FLDCs from SLE patients had a higher expression of CCR7 than did control. (b) Both control and SLE mature FLDCs and mDCs expressed higher levels of CCR7 than did immature FLDCs and mDCs, respectively. **P < 0.01; #P < 0.05. Results are expressed as mean ± standard deviation. NC, normal control; SLE, systemic lupus erythematosus; FLDCs, dendritic cells induced by FL; mDCs, myeloid dendritic cells induced by GM-CSF + IL-4; FL, FMS-like tyrosine kinase 3 ligand; GM-CSF, granulocyte macrophage-colony-stimulating factor; IL-4, interleukin 4.
