Laboratory of Immune-Neurobiology

Theme and Objectives

Growing body of evidence demonstrates a close link between mental disorders and inflammatory immune responses. However, the complex bidirectional interactions between the central nervous system (CNS) and the peripheral immune system in affective disorders are sparsely understood. The investigation of the underlying immune mechanisms implicated in major depression and depression-associated behavior is one major research topic of our lab. The specific focus of our studies is the phenotypic and functional characterization of dendritic cells and their effector molecules in vivo utilizing gene deficient and reporter mouse models. In translational approaches we determine immune signatures linked to severity of depression and treatment outcomes in individual patients. Our studies will lead to a better understanding of the relationships between the immune system and the CNS in depression with the future aim to identify immune-related markers of predictive relevance. A second research topic of the lab are neuroinflammation and neurodegeneration in Alzheimer`s disease. Here we employ mouse models of Alzheimer`s disease to characterize the impact of myeloid cells and the chemokine CCL17 in disease associated immune processes.
