Effect of curcumin on BV-2 microglial cell viability. (A) BV2 cells were treated with various concentrations of curcumin (5, 10, and 20 μM) for 24 h. (B) BV2 cells were preincubated with curcumin (5, 10, and 20 μM) for 1 h, and then exposed to LTA (5 μg/ml) for 24 h. Cell viability was measured by MTT assay. Statistical significance was determined by one-way ANOVA. All data were mean ±SD of three experiments.
