Several areas of mouse brain (cerebellum, brain stem, and hemispheres) contain levels of nerve growth factor (NGF) detectable by radioimmunoassay. However, this immunoactive NGF is not biologically active in the chick embryo sensory ganglia bioassay. Cerebellum from pcd mice, in which neuronal degeneration elicits a glial response, contains increased amounts of NGF immunoactivity. These results suggest that CNS glia may produce a NGF-like protein for CNS neurons.
