2004-06, Young Investigator's Award, National Alliance for Research on Schizophrenia and Depression (NARSAD), $60,000 direct costs, “A novel neuropeptide system in limbic thalamocortical structures and its role in schizophrenia”.
Our lab is interested in G protein-coupled receptors (GPCRs) and their physiological functions. We are studying GPCRs involved in stress, emotional behavior, sleep and wakefulness, and memory functions. The G protein-coupled receptors (GPCRs) are the biggest gene family in the human genome and represent the most successful drug targets of modern pharmaceuticals. With the sequence of the human genome at hand we now know, that there are at least 150 so-called "orphan" GPCRs which still await discovery of their natural ligands.

As one example, we have been working on the neuropeptide Orphanin FQ (OFQ; also called nociceptin) which we identified in 1995 as the endogenous ligand of an opioid-like receptor. We could demonstrate that OFQ is involved in stress regulation and anxiety behavior. A knockout mouse lacking the OFQ precursor protein shows increased susceptibility to stress and impaired adaptation to repeated stress, but is resistant to the development of morphine tolerance. A malfunction of the OFQ system might thus be involved in the pathology of human psychiatric diseases such as depression, anxiety or drug addiction.

More recently, we have identified a novel neuropeptide system (Neuropeptide S) in the brain that promotes arousal and anxiolytic-like effects. We are currently investigating the function of NPS in sleep and wakefulness, and its role in stress responses and learning & memory.

Our group uses molecular biology, cell biology, anatomical analysis, physiological and behavioral assays, and transgenic techniques to address fundamental questions about in-vivo functions of novel receptor-ligand systems, ranging from single cells to whole animal behavior.
