Dundee researchers receive £ 235,000 in funding for dementia science

Dundee researchers receive £ 235,000 in funding for dementia science

 


Dementia Awareness Week 2022

A Scottish researcher based at the University of Dundee received £ 235,000 to investigate how changes in the barrier between blood supply and the brain contribute to Alzheimer’s disease. This funding is part of Alzheimer’s Research UK’s £ 2 million commitment to 15 new research projects across the UK and will be announced during Dementia Awareness Week (Monday, May 30th to Friday, June 3rd). ..

Dr. Fiona McLean is a neuroscientist working to understand the causes of Alzheimer’s disease, the most common cause of dementia.

Amyloid is a characteristic protein that accumulates in the brains of people with Alzheimer’s disease. Researchers believe this causes other harmful processes that lead to symptoms such as memory loss and confusion. It can also be seen that in 80-90% of Alzheimer’s diseases, amyloid masses are embedded in blood vessels in the brain.

Blood vessels play an important role in supplying oxygen to our brain. However, the brain has a special group of cells that form a barrier between blood vessels and nerve cells. This protective layer is called the “blood-brain barrier.” These cells determine what goes into the brain and what doesn’t.

In her fellowship project, Dr. Fionama Clean of the University of Dundee will study the blood-brain barrier and how it differs in Alzheimer’s disease. The blood-brain barrier is exacerbated by illness, allowing toxic substances to enter the brain. Dr. McLean will investigate when and how amyloid accumulation disrupts the blood-brain barrier.

The goal is to find a way to reverse these changes in the blood-brain barrier and keep the brain healthy in the very early stages of Alzheimer’s disease.

Dr. Fiona McLean of the University of Dundee said:
“Funding from the UK Alzheimer’s Disease Study has allowed us to develop research that may ultimately help us in the search for future treatments for dementia.

“My work focuses on a group of specialized cells in the brain that form a barrier between blood vessels and the rest of the brain cells. This protective layer can enter the environment of our brain. It controls what you can do, but in diseases like Alzheimer’s disease, this barrier can leak and take up toxic molecules.

“My research hopes to provide insights into how the blood-brain barrier leaks in Alzheimer’s disease and find ways to delay, stop, or reverse it.”

Dr. Sara Imarisio, Head of Research at Alzheimer’s Research UK, said:
Sarah comments on morning sleep and dementia“Dementia affects nearly one million people in the UK, including about 90,000 in Scotland alone. This condition is not an unavoidable part of aging, but it is the result of a brain-damaging illness. The most common cause of dementia is Alzheimer’s disease, and groundbreaking research in Dundee has helped uncover the complex processes that contribute to its cause and drive progress toward new treatments. increase.

“Researchers are not the only ones who can make a difference when it comes to dementia research. To participate in important research, people with medical conditions and healthy volunteers need to urgently enroll.
