These processes transport materials from the soma towards the axon and from axon towards the soma.Anterograde and retrograde transport are two categories of axonal transport.What are the Similarities Between Anterograde and Retrograde Transport? Anterograde transport is important since it provides newly synthesized components such as membrane-associated enzymes, neurotransmitters, neuropeptides and membrane lipids, which are essential for neuronal membrane function and maintenance. Anterograde transport is facilitated by cytoplasmic motors kinesins. Through this process, nutrients, organelles, and other molecules are transported from the soma (cell body) to the distal axon. In anterograde transport, materials are transported towards the presynaptic terminals. Summary What is Anterograde Transport?Īnterograde transport is one of the two types of axonal transport. Side by Side Comparison – Anterograde vs Retrograde Transport in Tabular FormĦ. Similarities Between Anterograde and Retrograde Transportĥ. Moreover, motor kinesins facilitate anterograde transport while motor dyneins facilitate retrograde transport. In anterograde transport, materials are transported towards the presynaptic terminals while in retrograde transport, materials are transported from the periphery towards the cell body. Based on the direction of the material flow, there are two categories of axonal transport: anterograde and retrograde axonal transport. Axons are capable of bidirectional transport. In simple words, it is the process that involves the material transfer between the cell body and the axonal terminal of neurons. The key difference between anterograde and retrograde transport is that anterograde transport moves physiological materials towards presynaptic terminals while retrograde transport moves physiological materials back to the cell body from the periphery.Īxonal transport is a physiological process that transports proteins and other substances synthesized in the neurosome to the nerve endings through the cytoskeleton.
