Laboratory of Neuroscience and Molecular Pharmacology

Head: Raul R. Gainetdinov

Research Interests:

Monoamines dopamine, serotonin and norepinephrine are important neurotransmitters in the CNS that regulate various aspects of complex behaviours and motor activity. Brain disorders, such as depression, schizophrenia, bipolar disorder, Parkinson’s Disease and attention deficit hyperactivity disorder (ADHD) have been primarily related to the dysregulation of monoaminergic pathways, but the underlying mechanisms of these multi-transmitter dysfunctions remain elusive.  Many drugs clinically used in the management of these neuropsychiatric disorders, such as antipsychotics, psychostimulants and antidepressants, primarily act on monoaminergic neurotransmission.

Our laboratory uses a variety of techniques including genetic animal models, cellular systems, biochemical and molecular approaches to understand the pharmacology and role of monoamines and their receptors in health and disease. Investigations performed in mice with genetically enhanced or reduced monoaminergic transmission will be discussed. Particularly, we are using several genetic animal models of aberrant monoaminergic transmission generated by targeting plasma membrane transporters (DAT, NET), key synthesizing enzymes (TPH2), monoamine receptors, signal transduction and GPCR regulatory mechanisms (arrestins, GRKs).

We are also investigating the role of trace amines and their receptors (TAARs) in neuronal functions. These studies are eventually aimed to understand the molecular mechanisms involved in the manifestation of aberrant behaviors and responses to drugs that could be helpful to identify novel targets for pharmacological treatments of neuropsychiatric disorders. 

Major lines of research:

•GPCRs and GPCR desensitization machinery in regulation of brain monoaminergic functions
•Trace Amines and their receptors (TAARs) in the control of behavior
•Understanding dopamine neurotransmission: neuronal networks and synaptic mechanisms involved in dopamine-related behaviors and functions
•Development of genetic mouse and rat models to understand endophenotypes of schizophrenia
