Title
NMDA receptor functions in brain physiology and diseases
Abstract
Since the discovery of NMDA-Rs four decades ago, substantial efforts have been made to dissect their major contributions to neural physiology and pathologies. Indeed, NMDA-R functions encompass the regulation of neuronal migration, synaptogenesis, and maturation during development, as well as the initiation of long-term synaptic plasticity and fine-tuning of brain network activities and behaviors. Consequently, impairments in NMDA-R signaling contribute to devastating neurological and psychiatric disorders such as stroke, neurodegenerative diseases, autism, or schizophrenia, and the underlying mechanisms of NMDA-R dysfunctions have been under close scrutiny. More recently, an increasing corpus of studies highlights that NMDA-R physiology cannot be restricted to fluxing ions and involves additional facets controlling synaptic transmissions in health and disease (i.e., receptor channel properties, total expression, synaptic content, and nanoscale organization, extrasynaptic content, and surface diffusion). After a summary of my past achievements, I will develop my ongoing projects. The driving force of my project is to elucidate the functional role of new dimensions of NMDA-R physiology in brain development and in neural network remodeling underlying physiological and pathological processes.
