Astrocytes – a route to better treatments for Parkinson’s? Laura Project information Lead researcher Dr Laura Ferraiuolo Location University of Sheffield Cost £50,000 over 20 months Start date January 2016 Type of project Small grant Project code K-1506 Project background The majority of research in Parkinson’s is focused on dopamine-producing cells – the particular cells that are lost in the brains of those who have the condition. These cells play a vital role in coordinating movement, and as they gradually stop working and die, the symptoms of the condition worsen. Dopamine-producing cells may be the star of Parkinson’s research, but is there more to the story? The majority of cells in the brain are actually ‘helper’ cells called astrocytes whose main role is providing nutrients and a support for other brain cells. Research in other similar conditions has shown that if astrocytes don’t do their job properly, other brain cells die more quickly. Recent research in animal and cell models suggests this might also happen in Parkinson’s. Understanding the role of astrocytes could lead to new treatments. Their abundant number and crucial role in supporting other brain cells make astrocytes a very appealing therapeutic target. If we can find ways to make them work better it could have huge benefits for damaged brain cells. Laura thinks that energy production may be the key. All the cells in our bodies need to produce energy to do their jobs and stay healthy. We already know that the energy-producing batteries of cells – known as mitochondria – don’t work properly in brain cells that are affected in Parkinson’s. If mitochondria fail in astrocytes too this may be a discovery with exciting potential for developing future treatments. What the project will do The aim of this study is to understand how astrocytes may interact with the brain cells affected in Parkinson’s – and look for opportunities to use these helper cells in developing better treatments. First, the team will grow astrocytes from skin cells donated by people who have rareinherited form of Parkinson’s caused by a genetic mutation. They will then look to see how well the mitochondria are working in the astrocytes. Next they will study dopamine-producing cells and astrocytes when they sit side by side, as they do in the brain to see how they interact in different situations. Finally, Dr Heather Mortiboys (Senior Parkinson's UK Fellow and co-applicant on this new project) has already found drugs which boost the function of mitochondria. So Laura will test these drugs on our astrocytes (alone and with dopamine-producing cells) to see if they have a beneficial effect. How the research will help people with Parkinson’s This is the first study to investigate astrocytes - the most common type of cell in the brain as a potential target for new therapies in Parkinson’s. Laura hopes the results will inform future strategies for therapy - should we focus all our efforts on dopamine-producing cells or could targeting astrocytes provide added benefits to people with Parkinson’s? -----------------------------------------------------------------------------------------------------------------------Find out more about our research, visit our website: parkinsons.org.uk/research Or contact the Parkinson’s UK research team at: [email protected] Parkinson’s UK is the operating name of the Parkinson’s Disease Society of the United Kingdom.
