The mission of the Van Rijn lab is to uncover new strategies to treat psychiatric and neurological disorders. We specifically investigate the heavily co-morbid triad of ​drug use disorders, chronic pain disorders and mood disorders. Our primary target, the ​delta opioid receptor, is involved in the neuropharmacology of all three disorders and thus offers an exciting novel approach to treat these disorders. The Van Rijn lab covers all aspects of preclinical drug development including drug synthesis, drug screening, pharmacological characterization both in vitro and in vivo. We also perform mechanistic studies to improve our understanding of the etiology of these disorders.
