(B) Midbrain gba+/+ and gba−/− neurons and astrocytes were transfected with YFP-Parkin. Half the transfected cells were treated for 1 hr with 10 μM FCCP and all bathed in TMRM containing recording solution and imaged using confocal microscopy. Scale bar, 20 μm.(C) TMRM fluorescence intensity of cells from (B) was analyzed via confocal microscopy. Data represent the mean ± SEM, (n = 3, >4 cells analyzed per experiment).
