NMDA Receptors and Synapse Regulation
Our laboratory focuses on understanding the molecular and cellular mechanisms involved in synapse development and plasticity throughout the brain. In particular, we study the regulation of the NMDA-type glutamate receptors that play crucial roles in synapse development and synaptic plasticity. Because of these important functions, dysregulation of NMDA receptors has been implicated in a broad range of neuropsychiatric disorders, including schizophrenia, autism, addiction, Alzheimer’s disease, Huntington’s disease and ischemia. By combining innovative genetic approaches with electrophysiology, imaging, and biochemistry to gain a detailed understanding of the molecular mechanisms involved in the regulation of NMDA receptors and synapses, we are striving to open new frontiers for the development of disease-modifying therapeutic approaches for complex neuropsychiatric disorders.
