title: Regional changes of ciliary neurotrophic factor and nerve growth factor levels in post mortem spinal cord and cerebral cortex from patients with motor disease.
abstract: Ciliary neurotrophic factor (CNTF) rescues motor neurons in animal models of injury and neurodegeneration, and disruption of the mouse CNTF gene results in motor neuron degeneration in mature adults. Glial cells increase nerve growth factor (NGF) expression in neuropathological conditions, and the sensory system can be affected in the amyotrophic lateral sclerosis (ALS) type of motor neuronic disease. We therefore studied CNTF and NGF levels in post mortem spinal cord and cerebral cortex from patients with ALS and matched controls. We report a marked decrease of CNTF in the ventral horn of spinal cord in ALS, with no change in cerebral motor cortex. In contrast, NGF levels were decreased in ALS cerebral motor cortex, where the corticospinal tract originates, but increased in the lateral column of spinal cord, which includes the region of corticospinal tract degeneration in ALS. Both CNTF and NGF levels were decreased in ALS dorsal spinal cord.
