  1. Genetic mechanisms of schizophrenia – presentation of ERA-NET NEURONproject SYNSCHIZ - Budisteanu Magdalena, Papuc Sorina-Mihaela, Sorin Riga,Dan Riga, Arghir Aurora

  2. Schizophrenia (SZ) is a severe mental illness characterized by a wide range of defective cognitive function and a complex set of symptoms including hallucinations and delusions. • SZ represents one of the major challenges for society, with large unmet patient needs and substantial health care costs for the European community. • Various studies on the genetic risk architecture and aberrant brain functional connectome of SZ have implicated synaptic dysfunction in the pathophysiology, yet the precise mechanisms remain elusive. Objective

  3. Linking synaptic dysfunction to disease mechanisms in schizophrenia - a multi-level investigation (SYNSCHIZ) ERA-NET NEURON PROJECT

  4. Project Coordinator: • Norwegian Centre for Mental Disorders Research (NORMENT) - Ole A. Andreassen

  5. 2 Germany Marcella Rietschel Department of Genetic Epidemiology in Psychiatry, Central Institute of Mental Health • 3 Switzerland Stefan Borgwardt Research Group Neuropsychiatry and Brain Imaging, Department of Psychiatry, University of Basel • Finland Marja-Leena Linne Tampere University of Technology, Faculty of Biomedical Sciences and Engineering, Korkeakoulunkatu • 5 Netherlands Dirk Schubert Donders Institute for Brain, Cognition & Behavior, Cognitive Neuroscience Department, Radboud University Medical Center, Kapittelweg • 6 Romania Magdalena Budisteanu Prof. Dr. Alex Obregia Clinical Hospital of Psychiatry

  6. uncover the genetic architecture that increases the risk for synaptic dysfunction in SZ using large international cohorts and running multi-site replication studies; • integrate the identified genes into the development of novel, biophysically detailed computational models of synapse dysfunction. • validate these computational models experimentally in neuronal cell cultures derived from stem cells and create new knowledge on mechanisms underlying synaptic dysfunction in SZ. • link gene- and neuron-level discoveries to the level of brain network dysconnectivity in SZ and study similar associations in the SZ prodrome and in individuals at ultra-high risk for psychosis. The main aims of SYNSCHIZ are to:

  7. To identify clinically useful biomarkers, required for early detection and prognostic predictions in SZ, e.g. by using pluripotent stem cells as a screening tool. • To transfer scientific discoveries into clinical application for targeted treatment and care. Estimated results
