Figure 4. Nicotine treatment for one month improves social impairment in Thy1-aSyn mice tested at 6 months of age.
Thy1-aSyn mice treated with vehicle sniffed a beaker with a novel mouse (Mo) for less time than Wt mice treated with vehicle. Vehicle treated Thy1-aSyn mice did not show a preference for exploring a novel mouse (Mo) over an empty beaker (Em), but nicotine administration at 0.4 mg/kg/h for one month restored the interest in a novel mouse. Data are presented as mean ± SEM. Two-way repeated measures ANOVA followed by post hoc Bonferroni t test. *p<0.05, Thy1-aSyn-vehicle compared to Wt-vehicle; ^^p<0.01 compared within the group (empty beaker vs. mouse beaker).
