AAV-h-A53Tα-syn injection does not result in degeneration of the nigrostriatal dopaminergic pathway. Stereological count of nigral neurons and optical density of striatal TH + terminals were carried out in 12-month-old WT and LRRK2 KD mice 3 months after AAV-h-A53Tα-syn or AAV-GFP injection. Representative images and quantification of TH+ neurons in SNpc (A) and terminals in striatum (in grey scale arbitrary units; B). Data are expressed as mean percentage ± SEM of n = 6 mice per group (A) or n = 9 mice per group (B).
