Mouse glia were treated with various concentrations of AACOCF3 (Fig. 2A), MAFP (Fig. 2B) or BEL (Fig. 2C) two hours after plating. After overnight incubation, cells were treated with 5 μM MeHg (without inhibitors) overnight, and then the viability (open circles, left-side axis) and IL-6 levels in the medium (solid circles, right-side axis) were determined. IL-6 release caused by 5 μM MeHg was used as 100% in this set of analyses. Results indicated that all three PLA2 inhibitors decreased MeHg induced IL-6 release. Among them, BEL was the only one that could significantly prevent MeHg cytotoxicity.
