Our work group is interested in identifying the molecular mechanisms involved in the development of psychiatric disorders (particularly schizophrenia, affective disorders and their comorbidities). We mainly focus on synaptic mechanisms with a particular interest in proteins and protein interactions of the glutamatergic postsynapse. To investigate these mechanisms we employ a broad range of molecular, cytological and histological methods together with behavioral observations. One particular focus of our group is the selective transfer of genes into target brain areas using viral vectors (e.g. recombinant adeno-associated virus) and subsequent investigation of behavioral consequences. Moreover, we are making use of optogenetic stimulation in behaving animals to identify neural circuits involved in behaviors related to psychiatric disorders. Additionally, to further examine the underlying neurobiology and the role of our genes of interest in the pathogenesis of psychiatric disorders, we are also using genetically modified mouse strains with constitutive knockdown and inducible brain-region-specific overexpression of these genes combined with pharmacological manipulations targeting the protein interactions. Our current main interest revolves around neuronal nitric oxide synthase (NOS-I) and its interaction with proteins of the glutamatergic synapse. NOS1, the gene coding for NOS-I, and its adapter protein NOS1AP have repeatedly and consistently been associated with schizophrenia and integrity of NOS-I protein interaction has been suggested to be involved in the development of this disorder. We are investigating the importance of NOS-I/NOS1AP protein interaction using the above mentioned methods.
