Dr. Talbot's research interests lie in understanding how cells in the nervous system communicate. Many clinically important drugs, hormones, and neurotransmitters function by activating receptors present on the surface of nerve cells that couple to G proteins. The effects of these agents are determined by the extent to which these receptors and their G protein partners are activated. Recently, it was discovered that Regulators of G protein Signaling (RGS) Proteins are an essential mechanism by which the body controls this process. A major focus of our research is determining how RGS proteins influence the activity two important classes of drugs: (1) opioid pain relievers, such as morphine, hydrocodone (Vicodin), and oxycodone (Oxycontin) and (2) serotonin-related drugs that alter mood and anxiety such as selective serotonin reuptake inhibitors (SSRIs), such as paroxetine (Paxil) and citalopram (Celexa). To do this we have developed genetically-modified or "transgenic" mice that are otherwise normal yet lack RGS protein regulation. Our current studies involve characterizing how these mice respond to opioid and serotonin drugs in assays testing analgesic (pain relief), addictive, and antidepressant drug properties.
