(D) Midbrain gba+/+, gba+/−, and gba−/− astrocytes expressing GFP-DRP1K38A were immunostained for cytochrome c and mitochondrial morphologies analyzed; concurrently cells were stained with TMRM and fluorescence intensity analyzed via confocal microscopy. Scale bar, 20 μm (n = 3, >15 cells/experiment). All data in this figure represent the mean ± SEM.
