Figure 4. BACE1 impaired protective phenotype transition of microglia in vitro. (A) Quantification of cytokine gene expression is shown in the bar graphs, with data from at least 5 independent experiments. Data are shown as the relative change of the Ctrl group, *P < 0.05 and **P < 0.01. (B) Secreted IL-10 and IL-1β protein levels in the vehicle- and MK-8931-treated PMG measured by ELISAs. (C) Representative images of in vitro erythrophagocytosis of PMG, scale bar = 20 μm. (D) The percentage of erythrophagocytosis was calculated in the indicated treated PMG. (E, F) In vitro analysis of PMG erythrophagocytosis under Hb stimulation with/without MK-8901 treatment. The phagocytosis index was calculated as the median fluorescence intensity of the RBC-engulfed population, n = 3 per group. All data are presented as the mean ± SD. *P < 0.05, **P < 0.01.
