| Research Abstract |
Spinal cord injury is often followed by disuse muscle atrophy. The effect of disuse muscle atrophy on motor neurons below the level of spinal cord lesions is not fully understood. Alpha-motor neurons in L4/5 at 3 weeks postinjury showed signs of degeneration associated with disuse muscle atrophy. Muscle atrophy alone did not produce a significant alpha-motor neuronal degeneration.
Our results demonstrated GDNF was responsible for alpha-motor neuronal degeneration with disuse muscle atrophy and GDNF injection in muscle could prevent alpha-motor neuronal degeneration.
