Fig. 4From: Lupus serum IgG induces microglia activation through Fc fragment dependent way and modulated by B-cell activating factorPercentages of MHCII+ microglia under different conditions. a Effect of IgG in the SLE serum on the microglia activation. Bars represent the mean ± SEM of percentages of MHCII+ microglia in the mice of different group. b Effect of cytokine neutralization on the increase of percentages of MHCII+ microglia induced by SLE serum. *p < 0.05; **p < 0.01Back to article page
