Fig. 1. Effects of diallyl trisulfide (DATS) and lipopolysaccharide (LPS) on the cell viability of BV2 microglial cells. The cells were treated with various concentrations of DATS for 24 hours (A) or pre-treated with the indicated concentrations of DATS for 1 hour prior to 100 ng/mL LPS treatment for 24 hours (B). The cell viability was assessed with an MTT reduction assay, and the results were expressed as the percentage of surviving cells over control cells (no addition of DATS and LPS). Values represent the means ± SD of the three independent experiments.
