    RESEARCH INTEREST

    The G protein-coupled receptor (GPCR) superfamily is one of the largest human gene families comprising approximately 800 genes (2% of the human genome). These receptors regulate a wide diversity of patho-physiological processes. As such, they provide excellent drug targets and this is reflected in the fact that approximately 40-50% of currently prescribed drugs target GPCRs. Despite this, a relatively small number (~30) of the approximately 400 non-olfactory receptors are therapeutic targets, highlighting the great potential for the development of novel therapeutics. My PhD project focused on understanding aspects of desensitization, resensitization and trafficking of two GPCRs, both of which are receptors for the neuropeptides neuromedin U and neuromedin S. Through the two Neuromedin U receptors, these peptides regulate a variety of patho-physiological processes including blood pressure, the stress response, pain, cancer, feeding behavior and energy expenditure. For the current time, I’m further investigating these aspects using different endogenous agonists (hNmU-25 and hNmS-33) for these receptors (NMU1/2) to explore the possibilities of biased signaling. As a future interest, following evolution of GPCRs crystallization and generation of nanobodies towards a specific conformation of GPCRs, I am very interested in learning and applying these tools in the CNS Pharmacology and cancer fields. I am also interested to further understand how biased agonism mediate a selective event (signaling/trafficking) that may contribute to the discovery of novel therapeutic agents with a lower incidence of side effects.
