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.

The metabolism of clownfish – or anemonefish – decreases when their sea ‘homes’ are damaged by climate change, according to a new study.
The research – led by an international team of scientists from the University of Glasgow and CRIOBE, and published today in
Functional Ecology – found that exposure to bleached coral reefs can have a negative effect on the physiology and growth of anemonefish.
The study found that anemonefish living in bleached anemones for longer than a month progressively decreased their metabolism, had less growth and modified their behavior to become less active.
Mass coral bleaching is the result of extreme heat waves caused by worldwide climate change. On tropical reefs, anemones are home to anemonefishes. When anemones bleach, they don’t just lose their color, but also the algae that live in their tissues that provide energy to anemones and also anemonefishes.
