The Lykkesfeldt Lab


The Lykkesfeldt Lab studies disease mechanisms and therapy of major life style-associated human conditions by developing, using and refining in vivo experimental models, methods and clinical trials in an ethically and scientifically responsible manner. The Lykkesfeldt Lab trains highly qualified students and junior scientists within pharmacology, toxicology and biomedicine.


Our research and the students and scientists we train have a high international level and contributes globally to evidence-based disease prevention and treatment.

Research Interests

Redox imbalance in development and disease

Living cells are constantly exposed to reactive oxygen and nitrogen species which may lead to modifications of the cellular macromolecules, mutations and eventually cell death. Increased oxidative stress - i.e. an imbalance in the cellular redox homeostasis - is observed during e.g. smoking, aging and inflammation and has been associated with several chronic diseases including atherosclerosis and cancer.

In a variety of studies ranging from primary cells, cell & tissue culture, animal models to clinical trials, we study the effects of oxidative insults on the redox homeostasis as well as the possible benefit of intervention with bioactive compounds to selected groups of animals or humans. Together with measurements of oxidative damage-an effect of oxidative stress-we investigate the link between oxidative stress and various pathological conditions. Our primary goal is to understand the role and mechanism of altered redox status in disease development and thereby pave the road for better prevention strategies and pharmacotherapy for animals and humans. Key projects involve effects of vitamin C deficiency, non-alcoholic fatty liver disease and cardiovascular disease.
