In an effort to further understand the challenges facing in vivo imaging probe development for the N-methyl-D-aspartate (NMDA) receptor ion channel, we have evaluated the effect of glutamate on the Alzheimer's disease (AD) brain. Human post-mortem AD brain slices of the frontal cortex and anterior cingulate were incubated with [H]MK-801 and adjacent sections were tested for Aβ and Tau. The binding of [H]MK-801 was measured in the absence and presence of glutamate and glycine.
