P , P ’ - Irninodipropionitrile Impairs Retrograde Axonal Transport
P,fl-Iminodipropionitrile (IDPN), a neurotoxin, causes redistribution of neurofilaments in axons followed by the development of proximal axonal swellings and, in chronic intoxication, a distal decrease in axonal caliber. The latter changes are caused by a selective impairment in the slow anterograde axonal transport of neurofilament proteins. To assess the role of retrograde axonal transport in...
متن کاملRetrograde axonal transport: pathways to cell death?
Active transport along the axon is crucial to the neuron. Motor-driven transport supplies the distal synapse with newly synthesized proteins and lipids, and clears damaged or misfolded proteins. Microtubule motors also drive long-distance signaling along the axon via signaling endosomes. Although positive signaling initiated by neurotrophic factors has been well-studied, recent research has foc...
متن کاملRetrograde axonal transport of endogenous phospholipids in rat sciatic nerve.
Anterograde axonal transport of phospholipids occurs at a rate of several hundred millimeters per day. However, although labeled precursors are incorporated into phospholipids in the neuronal cell bodies within several hours, these newly synthesized phospholipids are committed to transport over a much longer period of time. Thus, maximal accumulation of radioactive lipids in axons and nerve end...
متن کاملLocating corticospinal neurons by retrograde axonal transport of horseradish peroxidase.
Different views of the location and organization of corticospinal (CS) neurons in the rat have resulted from fiber degeneration studies, electrophysiologically derived somatotopic maps, studies of CS axonal branching, and functional alterations af’ter ablation of parts of the motor-sensory cortex. To locate more precisely CS neurons that projected to different levels of the spinal cord, and to ...
متن کاملRetrograde axonal transport in the central nervous system.
When horseradish peroxidase is injected into the optic tectum of a chick, axons of ganglion cells transport it centripetally to their cell bodies in the retina at a rate of about 72 millimeters per day. After intraocular injections in the young chick, the peroxidase is transported centripetally along efferent axons, and is concentrated in cell bodies within the isthmo-optic nucleus. This retrog...
