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 of lipid in goldfish optic axons
Neurochemical Research, 1978After injection of labeled glycerol, choline, or serine into the eye of goldfish, labeled lipids were axonally transported along the optic nerve to the optic tectum. Although the different precursors were presumably incorporated into somewhat different lipid populations, all three were approximately equally effective in labeling the lipids transported ...

Abnormalities of the axonal cytoskeleton in giant axonal neuropathy
Journal of Neurocytology, 1988Intermediate filaments accumulate abnormally in a variety of cell types in individuals with human inherited giant axonal neuropathy (GAN). A characteristic feature of this disorder is the occurrence of focal axonal enlargements filled with accumulations of neurofilaments.

Fast Axonal Transport in Squid Giant Axon
Science, 1982Video-enhanced contrast-differential interference contrast microscopy has revealed new features of axonal transport in the giant axon of the squid, where no movement had been detected previously by conventional microscopy. The newly discovered dominant feature is vast numbers of "submicroscopic" particles, probably 30- to 50-nanometer vesicles and ...

Axonal oscillations in developing mammalian nerve axons
Physical Review E, 2005We study neuronal spike propagation in a developing myelinated axon in various stages of its development through detailed computational modeling. Recently, a form of bursting (axonal bursting), has been reported in axons in developing nerves in the absence of potassium channels.

Axon-to-axon transmission in tullidora (buckthorn) neuropathy
Experimental Neurology, 1984Oral administration of ether extracts of the tullidora ( Karwinskia humboldtiana ) fruit, which contains an identified neurotoxin, produced flaccid hind limb paralysis in cats after a latency of 4 to 7 weeks. Acute experiments were conducted after the paralysis was evident. Spinal roots of lumbar and sacral segments were transected as close as possible

Experimental Neurology, 2001
Injury to axons in the CNS leads to little regenerative repair and loss of function. Conversely, injury to axons in the PNS results in vigorous regrowth of severed axons, usually with restoration of function. This difference is generally attributed to a CNS environment that either cannot support or actively inhibits regeneration and/or a failure of CNS

Dynamic Condition of Protein in Axons and Axon Terminals
1971Radioautographic studies performed with labeled amino acids visualize the complexity of the dynamic state of protein in nerve endings. One protein fraction, at least, is replaced at a rate of 4% per day. On the one hand, the loss of used protein in presynaptic axon terminals seems to be balanced by the arrival of new migratory proteins, synthesized in ...

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.

Axonal transport in the central axon of sensory neurons during regeneration of their peripheral axon
Neuroscience Letters, 1981Following sciatic nerve injury (which provokes prompt regeneration of peripheral sensory axons) there was no change in the ratio between amounts of labeled protein conveyed by fast axonal transport into the central and peripheral axons. A change in composition of the transported protein, characteristic of regenerating peripheral axons, also occurred in
