• motor neurons have reduced neurofilaments, lack a well-spread filament network and exhibit a circular distribution of neurofilaments around the cell periphery
|
|
• increased muscle denervation
|
|
• motor neuron number is reduced in lumbar spinal cord at the end stage of disease (170-226 days)
• motor neuron number is reduced in the ventral horn of cervical spinal cord beginning at 132-154 days of age
|
|
• protein aggregates are visible by day 127 and gradually accumulate until death
• motor neurons exhibit widespread small particulates in the cytoplasm and neuronal processe
• 1-2% of motor neurons form large aggregates

|
|
• axon loss is progressive
• increased number of degenerating axons in the ventral root in 100-120 day old mice as compared to controls
• axon degeneration is observed in the dorsal root, but progression lags behind ventral root axons
• axon degeneration is observed in white matter of spinal cord; degeneration is mild in lateral column and more severe in ventral column
• little axon degeneration is observed in the cortical spinal track in the dorsal column
