Glutamate synapses and psychiatric disorders


Psychiatric disorders comprise a wide range of diseases (e.g. depression, schizophrenia, dementia) that exhibit abnormal thoughts, moods and behaviors and account for 12% of the global burden of all diseases 239. Pharmacological intervention for psychiatric disorders used to rely largely on drugs that manipulate monoaminergic transmission. Recently reported antidepressant and antipsychotic effects of drugs targeting glutamatergic transmission have raised a lot of interest in the field of psychiatry to understand the role of glutamate, the most commonly found excitatory neurotransmitter, in the neuropathology of psychiatric disorders. In addition, glutamatergic transmission is known to be highly changeable in an experience-dependent manner. Plastic properties of glutamate synapses, including long-term potentiation (LTP) and depression (LTD), have been regarded as cellular substrates for learning and memory. Malfunctioning of glutamatergic transmission could thus underlie cognitive impairment that is commonly associated with psychiatric disorders.

In this research program, we investigate mechanisms underlying changes in glutamatergic transmission in animal models that mimic psychopathologies of psychiatric disorders. These studies are primarily performed in the hippocampus, a brain region that not only is crucial in various cognitive functions, but also is affected in many psychiatric disorders. Findings from this research program will help us understand the contribution of malfunctioning glutamatergic transmission to psychiatric disorders and provide rationale and therapeutic targets for treating these disorders.

Dr. Tak Pan Wong moved to Montreal from Hong Kong in 1995 to pursue his PhD study under the supervision of Dr. Claudio Cuello and Dr. Yves De Koninck at McGill University. His postdoctoral training in the laboratory of Dr. Yu Tian Wang at University of British Columbia examined the molecular mechanism of synaptic plasticity. Since 2006, he has established his research laboratory at Douglas Institute to investigate the contribution of synaptic plasticity to rodent behavioral changes that are related to psychopathology of psychiatric disorders.
