Iba1 immuoreactivity in hippocampus following shipping or injections of either saline or LPS in peripubertal (6 wk) and postpubertal (8 wk) C57Bl/6 mice.

<p>Treatment with LPS increases Iba1 immunoreactivity (IR) in the (A) dentate gyrus, (B) CA1 and (C) CA3 of the hippocampus in both 6 wk and 8 wk mice, compared to age-matched saline-treated controls (*p<0.05). Shipping from the breeder facility also increases Iba-IR in the dentate gyrus and CA3 in 6 wk mice, compared to saline-treated controls (*p<0.05). Significantly greater than 8 wk, within the same treatment (^†p<0.05). Data represent mean Iba1-immunoreactivity + SEM.
