Neurofilament Polymer Transport in Axons
Neurofilament proteins are known to be transported along axons by slow axonal transport, but the form in which they move is controversial. In previous studies on cultured rat sympathetic neurons, we found that green fluorescent protein-tagged neurofilament proteins move predominantly in the form of filamentous structures, and we proposed that

Slow transport of unpolymerized tubulin and polymerized
A major issue in the slow transport of cytoskeletal proteins is the form in which they are transported. We have investigated the possibility that unpolymerized as well as polymerized cytoskeletal proteins can be actively transported in axons. We report the active transport of highly diffusible tubulin oligomers, as well as transport of the less diffusible neurofilament polymers. After
Slow Axonal Transport of Neurofilament Protein in Cultured
In fact, analyses of neurofilament protein transport in optic nerve axons using two dimensional PAGE, which allows separation of comigrating SCa and SCb proteins, has shown that there is a single population of neurofilament proteins that is transported at a broad range of rates, with no evidence for distinct stationary and moving populations

Neurofilaments at a glance | Journal of Cell Science
The earliest in vivo pulse-labeling studies of neurofilament protein transport by Lasek and colleagues were initially interpreted to support the idea that the labeled neurofilaments that undergo transport constitute the entire NF cytoskeleton within axons, which, according to this model, is continuously moving (Lasek et al., 1984; Lasek et al

Axonal transport: The orderly motion of axonal structures
One goal has been to determine whether the transport behavior of individual neurofilaments as observed in cultured neurons imaged over short time frames can explain the transport behavior of neurofilament proteins in axons observed over long time frames in vivo with the pulse-chase approach (Brown et al., 2005, Li et al., 2012).

Microtubule Transport in the Axon
The theory of MT transport in axons was first proposed on the basis of classic axonal transport studies conducted over two decades ago. In these studies, radiolabeled amino acids were introduced into a cluster of cell bodies in which they were rapidly taken up and utilized for protein synthesis (Lasek, 1988, Baas and Brown, 1997, Brown, 2000).

Axonal transport and neurodegenerative disease
The extended axons of motor neurons make these cells uniquely vulnerable to defects in active transport, so it is reasonable to propose that even when other defects, such as aggregation of mutant SOD1, are a proximal cause of disease, a secondary inhibition of axonal transport may play a critical role in the downstream pathogenic mechanisms.

Neurofilaments Are Transported Rapidly But Intermittently
Slow axonal transport conveys cytoskeletal proteins from cell body to axon tip. This transport provides the axon with the architectural elements that are required to generate and maintain its elongate shape and also generates forces within the axon that are necessary for axon growth and navigation. The mechanisms of cytoskeletal transport in axons are unknown. One hypothesis states that
