mRNA levels of inflammatory markers in the hippocampus. A) Interleukin-1β (IL1β); B) Interleukin-6 (IL6); C) Tumor necrosis factor α (TNF-α) and D) IFN-inducible protein 10 (IP10). NS, non-stressed female mice; PS, prenatally stressed females. Filled bars, animals treated with vehicle (VEH). Empty bars, animals treated with LPS. Data are mean ± SEM. *,**,** Significant differences (*P <0.05, **P <0.01; ***P <0.001) of LPS groups versus their respective VEH groups. a, significant differences (P <0.05) versus NS-LPS values. #, Significant difference (P <0.05) versus NS-VEH group.
