Location, location, location: contrasting roles of synaptic and extrasynaptic NMDA receptors in Huntington's disease.
Abnormally enhanced N-methyl-D-aspartate (NMDA) receptor function is implicated in Huntington's disease (HD). In this issue of Neuron and a recent issue of Nature Medicine, an abnormal balance between the activity of NMDA receptors at synaptic (prosurvival) and extrasynaptic (proapoptotic) sites has been uncovered in a cellular and a mouse model of HD.
