The laboratory of Dr. Lena Brundin investigates how inflammation in the periphery and central nervous systems contributes to neurological disorders, such as Parkinson’s disease, and psychiatric symptoms, such as depression, anxiety and suicidal thoughts/behavior.
Inflammation can be caused by many different factors and generates a cascade of cytokines, chemokines and metabolites that have intricate effects on neurons and other brain cells. The details of how inflammation impacts the central nervous system are just beginning to be understood. In our studies, we seek to identify inflammatory changes and link them to neurological symptoms. Through this approach, we aim to find novel therapeutic strategies that target inflammation and improve treatment outcomes.

Lena Brundin, M.D., Ph.D.
Professor, Department of Neurodegenerative Science
Areas of Expertise
Depression, suicide, inflammation, glutamate, perinatal depression, clinical studies, translational research
Dr. Lena Brundin earned her Ph.D. in neurobiology and her M.D. from Lund University, Sweden, where she specialized in clinical psychiatry and later attained the rank of associate professor. In 2012, she joined Van Andel Institute and Michigan State University College of Human Medicine in Grand Rapids, Mich. She is currently a professor in the Institute’s Department for Neurodegenerative Science.
Dr. Brundin’s research spans basic and clinical research, and focuses on the role of inflammatory mediators in psychiatric and neurological conditions, particularly the effects of the kynurenine metabolic pathway in depression and Parkinson’s disease. Her studies were among the first to indicate a role for inflammatory cytokines in suicidality, a finding that one day may help develop biomarkers for depression and suicide risk. She is currently the principal investigator on an R01-funded clinical trial that investigates the role of the kynurenine pathway in depressive patients with suicide risk. She also analyzes the potential of these metabolites as biomarkers and modulators of disease progression in Parkinson’s disease, funded by the Michael J. Fox Foundation. Further, she pursues studies aimed at identifying triggers of these disorders, such as bacterial, parasitic and viral infections.
