The specific binding of [3H]D-aspartate, a marker for the presynaptic glutamate uptake site, and [3H]N-(1-[2-Thienyl]cyclohexyl)-piperidine [( 3H]TCP), a high affinity ligand for the N-methyl-D-aspartate (NMDA)-associated phencyclidine binding site, was measured in homogenates of brain from normal subjects and from subjects with neuropathologically confirmed Alzheimer's disease. Alzheimer's disease was associated with a reduction in [3H]D-aspartate binding density in temporal cortex and caudate nucleus. By contrast, a reduction in the receptor density for [3H]TCP binding was only recorded in the frontal cortex. Thus, glutamate-containing nerve terminals are severely reduced in Alzheimer's disease, whilst the postsynaptic NMDA-phencyclidine receptor complex is much less affected. These findings have implications for theories of glutamate neurotoxicity in Alzheimer's disease.
