Radial expansion of axonal plasma membrane caused by passages of axonal cargoes. Time-lapse dual-color SIM images at 20-s intervals showing that diameter changes of axonal plasma membrane (CellMask Deep Red) correlate with the passage of large lysosomal cargoes (Lysotracker red). Diameter changes of axonal plasma membrane are indicated with arrows. Scale bar = 1 µm. Video is 1 frame/s.
