Rooted in recent wars, displacement, and socio-economic instability, Serbia has established a 13.5% increase in the prevalence of post-traumatic stress disorder (PTSD) and major depression, making them the second largest public health problem in this LMIC country. In parallel, the health system has deteriorated, facing multiple challenges in areas of basic and clinical research. Most recently, a health care reform has started to address these problems at different levels. This proposal aims to join this initiative by developing a collaborative program between Northwestern University (USA) and Vinca Institute (Serbia) in basic and translational research relevant for major affective disorders. The short-term goal of this collaboration is to initiate the discovery of molecular endophenotypes of PTSD by focusing on a newly proposed interaction between the glutamatergic and glucocorticoid (GC) systems.
After completing the study, we expect to have determined that membrane-impermeant GC will rescue the glutamatergic deficits underlying PTSD-like behavior without exacerbating depression-like behavior. The resources will be used for building capacity for PTSD research in Serbia by training LMIC personnel, acquiring research equipment, and generating pilot data for a large-scale proposal aiming to identify novel treatment, diagnostic, and prognostic molecular targets of PTSD. The long-term goal is to develop a strong translational program in Serbia in the area of major affective disorders and initiate cross-cultural studies between the collaborating institutions. The research is primarily designed to establish the use of blood molecular phenotypes for the diagnosis, prognosis, and treatment of patients suffering from major emotional disorders.
