Abstract:
Autoradiographic studies of high-affinity nerve growth factor binding sites in the cervical human spinal cord revealed a high density of binding sites in the dorsal horn and in the tract of Lissauer, which is in agreement with investigations in nonprimates. Very low or no binding was found in the motor neuron areas of controls as well as in amyotrophic lateral sclerosis cases, which indicates that the degeneration of motor neurons in this disease is not accompanied by re-expression of high-affinity nerve growth factor receptors.
