To clarify the roles of neurotrophins in the human spinal motoneurons, with special reference to amyotrophic lateral sclerosis (ALS), we studied the immunohistochemical localizations of neurotrophins and their receptors in spinal cords of patients with ALS and compared them with controls. In the controls, the majority of motoneurons showed BDNF-, NT3-, trkB- and trkC-like immunoreactivity (-LI) suggesting that the motoneurons receive an autocrine regulation by both BDNF and NT3. In ALS patients, about three-quarters of the motoneurons had degenerated and the remaining motoneurons showed significantly decreased BDNF-LI, increased NGF- and trkA-LI. These findings indicated neurotrophin-switching in the remaining spinal motoneurons of ALS patients from BDNF and NT3 responsive to NGF responsive.

D000690	Amyotrophic Lateral Sclerosis	A degenerative disorder affecting upper MOTOR NEURONS in the brain and lower motor neurons in the brain stem and SPINAL CORD. Disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years. Clinical manifestations include progressive weakness, atrophy, FASCICULATION, hyperreflexia, DYSARTHRIA, dysphagia, and eventual paralysis of respiratory function. Pathologic features include the replacement of motor neurons with fibrous ASTROCYTES and atrophy of anterior SPINAL NERVE ROOTS and corticospinal tracts.
