In addition, a dysregulation of the NMDA receptor signaling is likely involved in the etiology of neuropsychiatric diseases, such as schizophrenia. Here, Joana Ferreira and Thomas Papouin, from Laurent Groc (CNRS IINS) and St\u00e9phane Oliet (INSERM Neurocentre Magendie) labs, combined their efforts to demonstrate that NMDAR co-agonists, glycine and D-serine, are not only important for receptor activation, and therefore for ionotropic function, but also for the regulation of its diffusion properties and synaptic localization over time.<\/p>\n<p>They used a combination of techniques from single-particle tracking in rat hippocampal cultures, biochemistry, fluorescent lifetime microscopy to electrophysiology in acute slices, to unveil this mechanism. Remarkably, they showed that this process contributes to the change in the composition of synaptic NMDARs that occurs during development, a well-known feature of glutamatergic synapses that is central to neuronal network maturation. Since blocking the receptors has been proven to be therapeutically ineffective, altering co-agonist levels may be a viable alternative to regulate the NMDA receptors in severe psychiatric disorders.
