m(Ch)PrP-res^A568-labeled vesicles do not colocalize with GFP-Vacht, a synaptic vesicle marker. a, m(Ch)PrP-res^A568 distribution in the cytosol. b, GFP-Vacht accumulates in a perinuclear region and neuritic processes. c, Merged image (GFP-Vacht, green; m(Ch)PrP-res^A568, red). d, e, Magnifications of the merged images of neuritic processes (d, e) in c. Images are consistent with 26 cells in four independent experiments. Scale bars, 20 μm.
