Pregnane neurosteroids are dynamically regulated in the central nervous system during stress, menstruation, and pregnancy. Recent studies indicate that metabolites of progesterone such as allopregnanolone (ALLO) exert their anxiolytic effects on the gamma-aminobutyric acid Type A (GABAA) receptor, the major inhibitory neurotransmitter receptor. In my laboratory, we are interested in mapping the ALLO binding site on this receptor. Early studies suggest that changing the subunit composition of the receptor affects its sensitivity to ALLO. My laboratory uses a multidisciplinary approach, including biochemical, pharmacological, and physiological techniques, to resolve the molecular underpinnings of neurosteroid modulation of the GABAA receptor. Understanding the structure and function of this binding pocket will help us understand how ALLO may underlie the anxiety evoked during premenstrual syndrome, post-partum depression, and post-traumatic stress disorder. Additionally, these data may also yield important new information about the hormonal control of inhibitory circuitry in the central nervous system.
