Excitatory neurotransmission through NMDA receptors (NMDARs) has a pivotal role in healthy brain function, and its dysfunction has long been implicated in the pathogenesis of neurodegenerative disorders, including Huntington's disease. A new study uncovers a molecular link between mutant huntingtin and aberrant trafficking of an unconventional NDMAR subunit (GluN3A). Targeting this disease mechanism in a Huntington's disease mouse model had multiple therapeutic benefits (pages 1030–1038).
