title: Loss of nerve growth factor receptors in sympathetic ganglia from aged mice.
abstract: [125I]-Nerve growth factor (NGF) binding was studied in superior cervical ganglia from mice 4-7 months and 24-27 months of age. Scatchard analysis demonstrated losses of both high and low affinity components of NGF receptor. These results indicate loss of NGF receptors may lead to the diminished responsiveness to NGF in aged sympathetic ganglion neurons.
