Parkinson s disease has always been considered a brain disorder. However, new research reveals a close link between the disease and certain immune cells in the blood.
Researchers from Aarhus University have taken the first step on a path which can lead to new ways of understanding and, in the long term, possibly treating this widespread disease that affects not only motor functions but also cognition and emotions. We know that Parkinson s disease is characterized by an inflammation in the brain, and that this is crucial for the progression of the disease. But in the study, our interest has been focused on the immune cells found outside the brain, explains Marina Romero-Ramos, who is associate professor at the Department of Biomedicine at Aarhus University.
