Figure 2.
Aged LRRK2R1441G knockin mice have similar amounts of DA neurons and neurites compared to wild-type mice. (A, B) No apparent difference in the expression pattern of TH and DAT in SNpc and striatum between WT/WT and KI/KI mice at 18–22 months (N = 3). Scale = 150 μm in (A) and 200 μm in (B). (C) Statistical analysis of TH+ DA neurons numbers and neurite intensity of stained SNpc and striatum revealed no significant difference in combination of TH expression and cell count (unpaired Student's t-test, N = 3). (D) Western blot showed similar expression levels of TH and DAT (glycosylated and nonglycosylated) in striatum and midbrain in WT/WT and KI/KI mice at 3 and 18 months of age (N = 3).
