Abstract

We have investigated the distribution of NMDA and neurotrophin receptor systems and their reciprocal interactions in post-synaptic densities (PSD) purified from spinal cord. NMDA receptor subunits, trkA and trkB, but not trkC, were present in spinal cord PSD. The incubation of PSD with BDNF and NGF induced the phosphorylation of NR2A and B subunits. This phosphorylation was counteracted by antibodies directed against the catalytic domain of trkA and trkB receptors and by genistein. These results suggest the existence of a previously unexplored cross-talk between neurotrophins and NMDA receptors in rat spinal cord neurons.
