RESEARCH

Dr. Lynette Daws' research focuses on the function and regulation of biogenic amine transporters, including “classic” serotonin, dopamine and norepinephrine transporters, as well as organic cation and plasma membrane monoamine transporters; transporters that were recently identified as important regulators of central biogenic amine neurotransmission. These transporters are crucial for controlling concentrations of extracellular biogenic amines and therefore, the strength and duration of biogenic amine neurotransmission. Moreover, these transporters are primary sites of action for numerous psychotherapeutic and addictive drugs. 

Our lab utilizes an integrative and translational approach, including in vivo neurochemistry, behavior, in vitro biochemistry and cell culture, to understand how these transporters contribute to the etiology of psychiatric disease and how they may be harnessed as targets for improved therapeutic intervention.
