Research: Neuropharmacology and drug discovery

In my laboratory we use innovative strategies and techniques to provide a better understanding of the molecular mechanism by which G-protein coupled receptors (GPCRs) function, propagate signal transduction and modulate behavior. GPCRs form the largest protein family in the human genome and are crucial in relaying extracellular information into the cell. GPCRs are involved in many diverse physiological responses, including light perception, taste, immune responses, cardiovascular activity and neurotransmission. Currently, 30-40% of all drugs, approved by the Federal Drug Administration, target GPCRs. New insights into how these receptors work have re-energized the study of these receptors. Specifically, we study biased receptor signaling and GPCR heteromerization and potential overlap of these concepts and their roles in (patho)-physiological responses. We frequently use the delta opioid receptor as model receptor for our studies. We use a combination of in vitro cell culture assays, with in vivo mouse behavioral paradigms and ex vivo assays to perform translational/pre-clinical research with the goal of proposing and developing new therapeutic drugs that may have better potency, efficacy and fewer side effects. Our main focus is on neurological disorders, with an emphasis on drug addiction and co-morbid mood and anxiety disorders as well as chronic pain conditions. Current projects involve investigations into the risk of the alcohol mixed energy drinks, the role of beta-arrestin dependent signaling in depression and anxiety disorders, the physiological function of opioid-dopamine interactions and alcohol withdrawal induced hyperalgesia.
