Changes in gene expression in the hippocampus between early and the late post- induction day following PPA administration.

<p>Gene expression of a neuron-specific microtubule associated protein (<i>MAP2</i>) (A), an astrocyte marker (<i>GFAP</i>) (B), a neural stem cell marker (<i>OCT4</i>) (C), and a pro-inflammatory cytokine (<i>TNF-α</i>) (D) following PID 0 and during the late PID period (days 7 and 14). Data are shown as the mean ± SD. Cont, control rats; ASD, PPA-treated rats. ^<i>*</i><i>p</i> < 0.05, ^<i>**</i><i>p</i> < 0.01: <i>vs</i>. Cont.
