Figure Lengend Snippet: MCC950 markedly reduces cytotoxicity in striatal progenitor cells and BV2 microglial cells. A , B BV2 microglia were incubated for 4 h with LPS (1 μg/mL) followed by incubation with MCC950 (1 μM) for 2 h. The cells were then incubated with ATP (1 mM, 24 h). Total lysates of BV2 microglial cells were assessed by Western blot analysis to determine the levels of the NLRP3 and actin proteins. The molecular mass is indicated in kilodaltons. C , D BV2 microglia were incubated for 4 h with LPS (1 μg/mL) followed by incubation with MCC950 (1 μM) for 2 h. The cells were then incubated with ATP (1 mM for 24 h). Cell survival ( C ) and IL-1β expression levels ( D ) were measured using the CCK-8 assay and ELISA, respectively. The values of the indicated cells were normalized to those of untreated BV2 cells. * P < 0.05 compared to LPS/ATP treated cells ( n = 3). E , F ST Hdh Q109 cells were incubated for 24 h with MCC950 (1 μM). Total lysates of ST Hdh Q7 and ST Hdh Q109 cells were assessed using Western blot analysis. G ST Hdh Q7 and ST Hdh Q109 cells were incubated for 24 h with MCC950 (1 μM). Cell death was quantified using the CCK-8 assay; the values of the indicated cells were normalized to those of untreated ST Hdh Q7 cells. The data are presented as the mean ± SEM from three independent experiments. * P < 0.05, ST Hdh Q7 vs. ST Hdh Q109 cells; # P < 0.05 vs. untreated ST Hdh Q109 cells. H BV2 cells were incubated with LPS (1 µg/mL for 4 h) with or without MCC950 for 2 h before stimulation with ATP (1 mM for 24 h). The BV2 medium was then collected and used to culture the ST Hdh Q109 cells for an additional 24 h. ST Hdh Q7 and ST Hdh Q109 cell viability was determined by CCK-8 assay. The data are presented as the mean ± SEM from three independent experiments. * P < 0.05, ST Hdh Q7 vs. ST Hdh Q109 cells; # P < 0.05 vs. untreated ST Hdh Q109 cells. I BV2 cells were treated with or without MCC950 (1 μM) and 3-NP (5, 10, and 20 mM) for 24 h. The cell viability was determined using the CCK-8 assay. Data are presented as the mean ± SEM from three independent experiments. * P < 0.05 compared with controls ( n = 3)
