AAV-GDNF reduces the percentage of neurons with mHtt+ inclusions. WT mice never exhibited mHtt+ inclusions in the striatum (A). In contrast, transgenic mice, regardless of group (the example above is an AAV-eGFP-injected mouse), showed evidence of mHtt+ inclusions in the striatum (B). (E) Evidence of cells with robust inclusions. (C) Whereas no differences in the total number of striatal inclusions were observed between AAV-GDNF-injected mice and AAV-eGFP-injected mice (P > 0.05), a significant decrease in the percentage of neurons with inclusions was observed (D) (P < 0.01). (Scale bar: A and B, 500 μm; E, 10 μm.) Inclusion quantification was performed at week 16 of life.
