Abstract
Nerve growth factor (NGF) deprivation was produced in adult rats and guinea pigs by immunization against mouse NGF. Exposure of adult animals to anti-NGF had no effect on sensory ganglion neuronal number or size-frequency histograms. However, the substance P content of sensory ganglia, spinal cord and hind paw skin decreased to as great an extent as was seen in animals exposed to anti-NGF in utero. We conclude that NGF has two separate effects on sensory neurons: adult sensory neurons require NGF for normal function whereas developing neurons require NGF for both survival and transmitter expression.Entities:
