BAP31 protects neurons from lipopolysaccharide (LPS)-induced inflammatory cytokines. a Representative images of NeuN-labeled intact neurons in the hippocampal CA1 and DG areas. The intact neuron is shown in green. Scale bars = 200 μm. b Density of NeuN+ cells in the DG. (c) Density of NeuN+ cells in the DG. n = 12 per group for each experiment. n = 12 per group for each experiment. Data are expressed as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001 versus control group.
