Suppression of baicalein on MDSC inflammatory/oxidative abilities is involved in amelioration of pristane-induced lupus nephritis. Mice were treated as described in Fig. 1. a The frequency of MDSCs were determined by FACS in renal, splenic, BM, and Pbmc. b The statistical results of the frequency of MDSCs. c Immunofluorescence of glomerular GR-1 represents MDSCs. d The purity of sorted MDSCs from spleen was determined via flow cytometry. e Relative expression of Arg-1, P47 phox, GP91 phox, iNOS, NQO-1, HO-1, NLRP3, and IL-1β mRNA in MDSCs purified from the spleen were measured by QPCR. f, g ROS and MitoSOX production in MDSCs purified from the spleen was analyzed by flow cytometry. BA represents baicalein. Data represent the mean scores ± SEM. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001. n = 7 animals per group
