Forschungsschwerpunkt

Der Forschungsschwerpunkt Stress, Hypoxie und Psychoneuroimmunologie befasst sich mit psychologischen und biologischen Aspekten von akutem und chronischem Stress, und wie diese die Entstehung von stressbedingten Störungen fördern (zum Beispiel Angststörungen) und zu Prävention und Behandlung eingesetzt werden können. Wir interessieren uns besonders für die Interaktionen zwischen Änderungen der Sauerstoffverfügbarkeit in der Umgebung (zum Beispiel in der Höhe/im Gebirge), Stress und Bewegung, die Auswirkungen auf physiologische und biologische Funktionen haben.

Research Focus

In research focused on stress, hypoxia, and psychoneuroimmunology, we investigate the psychological and biological aspects of acute and chronic stress. We are interested in how these parameters promote the development of stress-related disorders (e.g., anxiety disorders) and how they can be used for prevention and treatment. A central line of research examines oxygen uptake and the interaction between changes in environmental oxygen availability (e.g., at high altitudes or in the mountains) and stress, affecting physiological and biological functions.

What are we currently working on?

1. Exploring the therapeutic potential of intermittent hypoxia in stress-related diseases

The availability and efficient utilization of oxygen, especially in the brain, are closely linked to psychological resilience and how we deal with stress (figure 1). We study the body's own protective responses to hypoxia and how their activation may protect against mental stress.

2. High altitude adaptations and the diagnosis and prevention of mountain illnesses
Different types of altitude sicknesses often affect the brain and can have serious neurological and psychological effects. The most common form of altitude sickness is acute mountain sickness, for which there are no objective diagnostic criteria, but stress appears to be a risk factor. We are studying the link between stress and altitude sickness and search for new diagnostic biomarkers.

3. The role of hypoxia and mitochondrial dysfunctions in psychiatric symptoms in neurological diseases
Neurological insults and diseases are usually associated with hypoxia and/or mitochondrial dysfunction in the brain, but also frequently with psychiatric symptoms such as anxiety or depression. We are developing methods that will hopefully lead to new treatment strategies, again via strengthening the hypoxia response, especially in the context of Parkinson's disease, Huntington's disease, multiple sclerosis, and stroke.
