a Cytokine mRNA expression levels of TNF-α, Il-1β and Il-6 in the brain tissues 24 h after LPS injection. b the levels of Iba-1 and TSPO at 3 and 24 h after injection of 5 mg/kg LPS determined by immunoblots, c Quantitative analysis of protein levels of immunoblots. Data are mean ± SEM (n = 3 mice per group); *p < 0.05, **p < 0.01, ***p < 0.005
