Western blot analyses of TH and ChAT in protein extracts from the left and right sides of the SN in mice challenged with right intranasal LPS (10 µg/every other day) or saline administration of for 5 months.

<p>Semi-quantification of relative TH and ChAT protein was obtained from among at least six different animals. *<i>P</i><0.05 and ***<i>P</i> <0.01 compared with the contralateral SN and saline control, respectively.
