WebThe dying back hypothesis proposes that ALS is primarily a disorder of the lower motor neurons, with pathogens retrogradely transported from the neuromuscular junction to the cell body where they exert their deleterious effects.173 Although some pathological studies have indirectly supported a dying back process,174–176 no pathogens of any ... WebMay 13, 2014 · Amyotrophic lateral sclerosis (ALS) is characterized by the progressive loss of motoneurons and degradation of the neuromuscular junctions (NMJ). Consistent with the dying-back hypothesis of motoneuron degeneration the decline in synaptic function initiates from the presynaptic terminals in ALS. Oxidative stress is a major contributory …

WebAug 10, 2024 · The dying forward hypothesis proposes that ALS begins centrally, with corticomotoneuronal hyperexcitability mediating anterior horn cell degeneration via a glutamate mediated excitotoxic process. The dying back hypothesis suggested that ALS is primarily a disorder of lower motor neurons, with pathogens retrogradely transported … WebApr 11, 2024 · In the dying forward hypothesis, it is theorised that ALS results in anterograde corticomotor neuron degeneration. Dysfunctional astrocytic excitatory amino acid transporter 2 is implicated in reduced glutamate uptake at the synaptic cleft. Ultimately, degradation of the anterior horn cells ensues due to excitotoxicity. In the dying back ... WebMar 20, 2024 · In contrast, the dying back hypothesis proposes that ALS begins within the muscle or neuromuscular junction, with pathogens being retrogradely transported from the neuromuscular junction to the cell body where they may exert their deleterious effects.
