The effects of lithium and lipopolysaccharide (LPS) on cell viability in primary microglia. The microglial cells were exposed to different concentrations of LiCl (0.1, 0.3, 1, and 3 mM) and/or LPS (10 ng/ml) for 24 hours. Cell viability was determined using a colorimetric method. Each data point represents the mean ± s.e.m. of at least three separate experiments in which treatments were performed in quadruplicates.
