nervous system
• YFP+ neurons exhibit one or more grossly enlarged, rounded mitochondria in the perinuclear region of the soma and in proximal segment of dendrites with some cells containing fragmented mitochondria and small, spherical mitochondrial clustered around the nucleus
• YFP+ neurons exhibit a progressive reduction in distal axonal mitochondrial numbers compared with control cells
• however, mitochondria in the distal dopamine axons are morphologically spared
|
• neurons exhibit less intense staining with a retrograde tracer (fluorogold) suggesting impaired retrograde transport and/or uptake of the tracer compared with control cells
