Research Focus: We have devoted the past 20 years to studying the immunological and molecular basis of prion pathogenesis. Currently, the primary focus of the lab lies on elucidating mechanisms underlying a) replication of prions and prion-like proteins such as alpha-synuclein and b) neurotoxicity in prion diseases. We approach these objectives from different directions. On one hand, we have established highly automated platforms for cell-based assays in order to screen for genes that are important for either prion replication or toxicity. On the other hand, we use a variety of model systems for genetic and infectious prion disease including cell culture models such as human IPS-cell derived neurons, ex vivo brain slice cultures and various transgenic and knockout mouse models in order to investigate molecular pathways underlying prion toxicity and pathogenesis.

Keywords: Neurodegeneration, neurotoxicity, prion disease, organotypic brain slice cultures, generation of transgenic and knock-out mouse models, high-throughput screenings

Research Focus: Our research focuses on a group of human Mendelian disorders called ciliopathies which are unified by shared genetic causes resulting in primary cilium dysfunction. Primary cilia are small non-motile organelles present on the surface of most vertebrate cells where they are involved in transduction of sensory, mechanical or chemical signals and in regulation of signalling pathways during development and cell homeostasis. Typical clinical presentations of ciliopathies include neurological involvement, retinal degeneration and renal fibrocystic disease, as illustrated by Joubert syndrome (JS), an iconic ciliopathy which is the main focus of our research. To understand the consequences of mutations in JS-associated genes at the molecular level, we combine observations from human genetics studies on JS-patients with modelling in the zebrafish system using state-of-the-art techniques such as crispr/Cas9 genome editing or live imaging of transgenically-tagged ciliary proteins.

Keywords: ciliopathies, primary cilia, Joubert syndrome, zebrafish

Research Focus: Inflammation is recognized as a major pathophysiological factor in several CNS disorders. The goal of our research is to elucidate the pathways via which inflammation affects specific brain circuits and consequently influences the emergence of brain dysfunction and behavioural symptoms. In particular, we are studying the role of extracellular vesicles (EVs) secreted by immune cells in mediating neuro-immune communication and in driving neuro- and psycho-pathologies during inflammatory conditions. We are also interested in understanding the mechanisms responsible for the motivational dysfunctions induced by inflammation.

Keywords: inflammation, stress, extracellular vesicles, dopamine system, motivation

Research Focus: The aim of the Swiss Space Travel and AiR Sickness (SSTARS) group is to investigate the mechanism of habituation and learning of self-motion perception in novel motion environments. A novel motion environment is any condition in which our brain fails to correctly interpret the motion stimuli. Such environments (from cars and ships to virtual reality and artificial gravity environments) cause motion sickness, spatial disorientation and other syndromes affecting performance and social interaction (sopite syndrome, mal de débarquement). Within our research activity, we develop non-invasive habituation protocols to counteract these conditions. The applications range from vestibular rehabilitation, acceptance of novel emerging technology (self-driving cars, virtual reality systems), quality of life and safety in transport systems. An important focus is on vestibular physiology for aviation and space flight (in flight, micro- and artificial gravity) in collaboration with the German Aerospace Center – DLR and the Swiss Aeromedical Institute.

Keywords: Motion sickness, vestibular space physiology, artificial gravity, virtual reality sickness, self-motion perception, sensory habituation

Research Focus: Neuro- and Tumorimmunology

Our research aims to understand the development of tissue-specific autoimmunity in particular in the context of interactions of the nervous system with the immune system. Our main research interests can be categorized as such:

  • Cytokine networks in autoimmune inflammatory disease with a focus on in vivo modeling of multiple sclerosis, psoriasis, graft-versus host disease
  • Immune tolerance and lymphoid development
  • Tumorimmunology: specifically the interaction of immune cells with cancer cells and therapeutic interventions to mount immune responses against tumors

Keywords: Transgenic mice, cytokines, immunity

Research Focus: We are interested in understanding the organism-wide consequences of stress, and how the complex stress-response leads to changes in behavior and increases the risk for neuropsychiatric disease. We use mice as a model organism to study stress-induced effects in the CNS, but also in the germline. We use optogenetic, transcriptomic, pharmacologic, epigenetic and behavioral approaches combined with assisted reproductive techniques.

Keywords: stress, anxiety, transcriptome, hippocampus, epigenetic inheritance, epigenetics

Research Focus: We focus on mapping brain functions and plasticity in typical development, neurodevelopmental disorders, and treatment with electrical and multimodal imaging (EEG-fMRI, MRS, with S. Brem). Clinical projects cover longitudinal brain mapping in common neurodevelopmental disorders like Attention-Deficit/Hyperactivity Disorder (ADHD), aggression and Dyslexia. We characterize timing, localization and genetics (with E.  Grünblatt) of compromised networks as endophenotypes as state dependent deficits during rest, attention, inhibition, reward processing, or print tuning etc.  For clinical translation we focus on neurofeedback and biofeedback training (with R. Drechsler), and evaluate potential biomarkers using multimodal approaches.

Research Focus: One focus is on space representation in healthy individuals and patients with hemispatial neglect. The “space” we are interested in is not confined to physical space, but comprises imagined locations, number space and the spatial representation of time. A very special, private part of space is our body. We are interested in the relations between corporeal awareness and the construction and experience of the self. This experience can change after brain damage, but can also drastically deviate from the norm in a minority of apparently healthy individuals. Cognitive dysfunction in a demyelinating disorder, multiple sclerosis, represents a further focus of interest. Here we are specifically interested in the relative contributions of white matter and gray matter lesions to cognitive performance, specifically executive functions. Generally, our strengths are in behavioral methods; structural and functional neuroimaging may complement the behavioral approach.

Keywords: Processing of space and time, body and self, structural correlates of cognitive dysfunction

Research focus: Neural algorithms and behaviour

How does the brain solve complex problems? The Burdakov lab studies brain computations that convert sensory context into appropriate actions, appetites, and arousal. Our experiments focus on specific genetically-defined brain cells, but our questions are more general, overlapping with fields such as robotics (what control algorithms are best for performance in an uncertain world? what are their strengths and weaknesses?).  To answer such questions, the lab studies how information is represented by specific neural clusters to sway decisions.

This is achieved by tracking real-time brain network dynamics (using in vivo genetically-targete­­d calcium reporters, electrophysiology) associated with quantified voluntary actions, while manipulating sensory contexts (internal and external body state) and genetically- and temporally-defined elements of neural computations (using optogenetics, chemogenetics). These sensorimotor measurements are interpreted with the help of computational simulations that formally assess the performance of particular sensorimotor algorithms in defined tasks.  By elucidating what different parts of the brain do, how they do it, and what makes them perform well or badly, this work provides fundamental information that can be used for designing better medical treatments for brain disorders.

Research Focus: Malignant gliomas are deadly brain tumors. Prominent biological features of these tumors include excessive invasive potential, as well as suppression of anti-tumor immune surveillance. Glioma-derived transforming growth factor (TGF)-β is a key player in these processes and TGF-β signaling has been shown to be fundamental in the maintenance of tumorigenic activity of glioma stem cells. Novel approaches of immunotherapy to enhance the immunogenicity of glioma cells may thus focus on members of the TGF-β superfamily. Specific objectives of our research include mechanisms of glial TGF-β secretion and activation underlying glioma immune escape. Through particlular emphasis on glioma stem cells, we aim to understand the molecular mechanisms of TGF-β activation, the underlying signaling pathways, and the role of the extracellular microenvironment.

Keywords: neurooncology, glioblastoma, glioma stem cells, transforming growth factor (TGF) -β
