Class IV da neurons in KhcmutA larvae maintain Rab5 vesicle motility. Representative time-lapse movies of control and KhcmutA class IV da neurons, expressing ppk > YFP-Rab5. The movie repeats with a zoom-in of control and KhcmutA dendrites, oriented such that retrograde transport events travel to the left and anterograde events to the right. Note that both control and KhcmutA Rab5 vesicles robustly move. (Scale bar, 50 μm.)
