Behavioral Medicine

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.
