    Abstract

    The neuronotrophic factor NGF binds to peripheral neurons of the dorsal root ganglion and the sympathetic nervous system. NGF binds to a cell surface receptor, NGFR, on these cells and displays Kd's of 10-9 and 10-11M. NGF receptors have also been reported for basal forebrain magnocellular neurons. In addition, NGF specifically binds to NGFR on Schwann cells although the biological significance of this binding is not known. Here we report that NGF binds in a saturable and specific fashion to receptors on cultured isolated populations of rat astrocytes but not to oligodendrocytes. The binding to astrocytes in culture displayed a Kd of 2.7 ± 1.0 nM with 36,000 receptors per cell.
