Fig. 3. Overexpression of TOM20 was neuroprotective against AAV2-αSyn-mediated dopaminergic neurodegeneration.

Fig. 3

Dopaminergic terminals within the striatum (tyrosine hydroxylase; TH; red) were significantly reduced compared to the contralateral side in animals expressing AAV2-αSyn/GFP, but not in animals expressing AAV2-TOM20/αSyn; TH (red), αSyn (cyan), GFP (green); (F(5, 95 = 3.0), p = 0.0146, ANOVA; a, b). Representative images from the ipsilateral and contralateral hemispheres of each treatment group show significant dopaminergic neuron loss (TH, red) following AAV2-αSyn/GFP treatment, which was reduced by co-expression with TOM20 (AAV2-TOM20/αSyn); (F(5, 20 = 12.07), p < 0.0001, ANOVA); scale bars 100 μm (c, d). Error bars depict standard error of the mean (s.e.m.).
