AEA increased the metabolic activity of HT22 cells exposed to H₂O₂ in a dose-dependent manner. (a) The correlation between the H₂O₂ concentration and cell metabolic activity. HT22 cells were exposed to different concentrations of H₂O₂ for 3 h (n = 8). (b) AEA increased the cell metabolic activity of HT22 cells exposed to 200 μM H₂O₂ for 3 h (n = 8). Results are expressed as means ± SD, *P < 0.05, ***P < 0.001 versus the control (no H₂O₂, and no AEA), ^# P < 0.05 versus the cells exposed to H₂O₂ alone.
