New studies provide further evidence that the neuronal cytoskeleton is the product of a dynamic interplay between axonal transport processes and locally regulated assembly mechanisms. These data confirm that the axonal cytoskeleton in mammalian systems is largely stationary and is maintained by a smaller pool of moving subunits or polymers. Slow axonal

Persistence of Axonal Transport in Isolated Axons of the Mouse
European Journal of Neuroscience, 1993AbstractWe have examined the hypothesis, for the case of mouse axons, that isolating an axon from its cell body will lead to a rapid failure of fast axonal transport as anterogradely moving organelles vacate the axon in a proximo‐distal direction, and retrogradely moving organelles vacate it in the opposite direction.

Axonal transport and the cytoskeleton
Current Opinion in Neurobiology, 1993Great advances in the field of axonal transport have been made in the past year, including the identification of new molecular motors associated with microtubules and actin. In addition, studies on the mechanisms of bidirectional fast axonal transport have clarified new aspects of this process, such as the isolation of a kinesin-binding protein ...

A model for fast axonal transport [PDF]
Cell Motility, 1985 AbstractA model for fast axonal transport is developed in which the essential features are that organelles may interact with mechanochemical cross‐bridges that in turn interact with microtubules, forming an organelle‐engine‐microtubule complex which is transported along the microtubules.

Axonal transport—II. Convection [PDF]
Bulletin of Mathematical Biology, 1976 The phenomenon of axonal transport has been well documented (Ochs, 971; Lasek, 1970; and Grafstein, 1967). In a previous paper, we showed how diffusion alone could not account for this process. In this report we show that convection or convection with diffusion can account for the observed build-up of material.

Axonal transport is a constitutive process that supplies the axon and axon terminal with materials required to maintain their structure and function. Most materials are supplied via three rate components termed the fast component, slow component a, and slow component b. Each of these delivers a distinct set of materials with distinct transport kinetics.

Axonal transport versus dendritic transport
Journal of Neurobiology, 2003AbstractNeurons have polarized processes for information output and input, axons, and dendrites. This polarized architecture is essential for the neuronal function. An increasing number of molecular components that mediate neuronal polarity establishment have been characterized over the past few years.

Microtubule Transport in the Axon
2002There has been a great deal of interest in how the microtubule array of the axon is established and maintained. In an early model, it was proposed that microtubules are actively transported from the cell body of the neuron down the length of the axon.

Retrograde Axonal Transport [PDF]
, 1983 Intracellular movement of organelles is one of the fundamental characteristics of living cells. It is indispensable for the efficient distribution of materials and thus for the proper cellular function of eucaryotic cells, which are highly organized entities in which many functions are compartmentalized and carried out by specific substructures.

Axonal transport in the asymmetric optic axons of flatfish
Experimental Neurology, 1974Abstract Axonal transport of protein was studied in the asymmetric optic axons of adult flounders, Pseudopleuronectes americanus . In these animals, the right optic nerve averaged 36% longer than the left optic nerve. There was no significant difference between the two sides in optic tract length or retinal ganglion cell body size.
