kirill [66]

Disruption of axonal transport would be a good target for his drug.

<h3>What is disruption of axonal transport?</h3>
  • Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS).
  • Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS.
  • Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias.
  • The neurotoxin β,β′-iminodipropionitrile (IDPN) selectively disrupts slow axonal transport without affecting fast anterograde or retrograde axonal transport.
  • Impairment of slow axonal transport causes a proximal accumulation of neurofilaments.
  • Because neurofilaments regulate axonal diameter, this accumulation leads to a marked swelling of the axon.
  • Acrylamide causes decreased axonal transport, also causing proximal accumulations of neurofilaments and swelling.
