Neurobiological mechanisms in the prevention and treatment of major depressive disorder

Research
We investigate the neurobiological mechanisms that underlie major depressive disorder and influence the response to antidepressant treatment. Our aim is to improve prevention and treatment by applying a pathophysiological perspective.

Our research is centered around the neurobiological mechanisms of major depressive disorder and how these can be reversed with traditional and novel antidepressant treatment, with a specific focus on psychedelic compounds, including ketamine and psilocybin. We investigate how central processes in the brain are reflected in blood to identify markers that can be used to advance the prevention and treatment of major depressive disorder from a pathophysiological perspective. Our translational approach includes clinical research aimed at the identification and validation of blood-based biomarkers of antidepressant response and individual depressive symptoms as well as preclinical research investigating the neurobiological effects of traditional and novel antidepressant agents in both blood and brain tissue using animal models of treatment-resistant depression.

Main objectives of our research:

  1. The identification and validation of blood-based biomarkers of the antidepressant and antisuicidal efficacy of traditional and novel antidepressant treatment.
  2. Compare the antidepressant efficacy of traditional and novel antidepressant agents from a pathophysiological perspective.
  3. Investigate the involvement of sleep and circadian rhythmicity in the antidepressant efficacy of different antidepressant treatments.
  4. Elucidate how individual symptoms of depression influence pathophysiological mechanisms to uncover novel approaches for prevention and treatment.
