mortality/aging
• survival is prolonged by injections of ciliary neutrophic factor (CNTF) delivered via an engineered CNTF construct in tranfected mouse D3 cells
(J:1717)
• mice die by 6-7 weeks of age
(J:30914)
|
muscle
• pelvic girdle and hind limb muscles atrophy and become paralytic; atrophy and paralysis of the forelimbs and respiratory musculature follow later
• skeletal muscle atrophy is caused by denervation
|
• in hindlimbs by the end of post-natal week three
• motor function is improved after injection of ciliary neutrophic factor (CNTF) delivered via an engineered CNTF construct in tranfected mouse D3 cells
|
nervous system
• progressive caudo-cranial degeneration
|
• loss of motor axons here is reduced by ciliary neutrophic factor (CNTF) delivered via an engineered CNTF construct in tranfected mouse D3 cells
|
• 30% of nerve fibers are lost by 28 days of age
• loss of motor axons here is reduced by ciliary neutrophic factor (CNTF) delivered via an engineered CNTF construct in tranfected mouse D3 cells
|
• the motor, but not the sensory, axons of the peripheral nerves degenerate, starting at the motor endplates and dying back proximally
|
respiratory system
• mice die of respiratory failure by 6-7 weeks of age
(J:30914)
