Monoclonal antibodies against human NGF receptor have been used for
immunocytochemical localization of NGF receptors in the CNS of macaques and
baboons at various stages of development. In the adult, neurons in most
brain regions are devoid of detectable NGF receptors. However, abundant NGF
receptor immunoreactivity is present on a population of neurons in basal
forebrain, which, on the basis of appearance and pattern of distribution,
probably correspond, at least in part, to magnocellular cholinergic neurons
of this region. NGF receptors were also associated with the vasculature in
most brain regions. NGF receptor immunoreactivity is present on Mueller
glia of neural retina. In macaque fetuses, approximately 1 month
prenatally, retinal Mueller glia possess lower levels of receptor, while
higher levels of receptor are present in the retinal nerve fiber layer. In
fetal cerebellum, abundant receptor immunoreactivity is present on Purkinje
cells, granule cells of the premigratory zone of the external granule
layer, and neurons of the deep nuclei. Immunoreactivity decreases with
subsequent development and is absent in the adult. In cerebellum, levels of
NGF receptor assayed by affinity crosslinking to radioiodinated NGF, and
levels of NGF receptor mRNA assayed by Northern blot analysis decrease
dramatically during the last month of fetal life.
