axonal transport

Friday 18 February 2005

Definition: Axonal transport is an active, directional transport of organelles and molecules along the axon driven by specific motor proteins running along microtubules. Anterograde and retrograde axonal transport move cargoes away from and towards the cell body, respectively.
