StemCell Therapy

Scientists from the University of Sheffield and University of Manchester have been awarded 265,000 from the British Heart Foundation, to investigate the links between vascular dementia and heart disease, and test whether a drug currently used to treat arthritis could also be used as a treatment for vascular dementia.

Vascular dementia is common, accounting for 15 percent of all cases of dementia. Caused by an impaired blood flow to the brain, symptoms of vascular dementia include confusion, slow-thinking, and changes in mood and behaviour.

Heart disease is a known risk factor for vascular dementia, and preliminary research by the Sheffield scientists has shown that blood flow in the brain is substantially affected by heart disease. The new study will continue this research to examine in more detail how heart disease and vascular dementia interact together, potentially making the disease burden worse.

The project will also investigate an anti-inflammatory treatment to reduce neuroinflammation in the brain and test whether this slows down, or reduces the severity of, vascular dementia.

Led by Professor Sheila Francis, from the University of Sheffields Department of Infection, Immunity, and Cardiovascular Disease, the project brings together the disciplines of cardiovascular biology and pathology, neurovascular function and neuropathology.

Dr Jason Berwick and Dr Clare Howarth from the Department of Psychology at the University of Sheffield also make up members of the research team who worked in collaboration with a team from the University of Manchester led by Professor Stuart Allan and Dr Emmanuel Pinteaux.

Professor Sheila Francis, from the University of Sheffield, said: We noticed quite a few years ago that laboratory mice with severe atherosclerosis (a type of heart disease) exhibited significant behaviour changes. On closer examination, their neurovascular function was altered, leading to the death of brain neurons and increased brain inflammation caused by a protein called interleukin-1.

The study will compare this new model with the commonly used laboratory models of vascular dementia to investigate whether an anti-inflammatory drug against interleukin-1 already used successfully to treat arthritis and in clinical trials for use in stroke patients, could also improve neurovascular function in both cases.

Professor Stuart Allan from the University of Manchester, commented: We are delighted to be involved with this project. We have worked on the role of the protein interleukin-1 in stroke for many years. Our research has led to several clinical trials of an anti-interleukin-1 therapy in stroke, and the possibility that this same treatment might work in vascular dementia is really exciting.

It is hoped the study will lead to anti-interleukin-1 therapies becoming a useful treatment for vascular dementia.

The work forms part of the research of two of the flagship institutes at the University of Sheffield:

Subreena Simrick, Senior Research Adviser at the BHF, said: There is no cure for vascular dementia. Currently, all that doctors can do is prescribe drugs which can slow down its progression.

By funding this research, we hope to take a step towards changing that and bring hope to people affected by this cruel disease.

Unfortunately, our ability to fund important research like this is threatened by the impact of coronavirus on our fundraising. Now, more than ever, we need the support of the public so we can continue to support projects that could transform the lives of those with heart and circulatory diseases.

The University of Sheffield

With almost 29,000 of the brightest students from over 140 countries, learning alongside over 1,200 of the best academics from across the globe, the University of Sheffield is one of the worlds leading universities.

A member of the UKs prestigious Russell Group of leading research-led institutions, Sheffield offers world-class teaching and research excellence across a wide range of disciplines.

Unified by the power of discovery and understanding, staff and students at the university are committed to finding new ways to transform the world we live in.

Sheffield is the only university to feature in The Sunday Times 100 Best Not-For-Profit Organisations to Work For 2018 and for the last eight years has been ranked in the top five UK universities for Student Satisfaction by Times Higher Education.

Sheffield has six Nobel Prize winners among former staff and students and its alumni go on to hold positions of great responsibility and influence all over the world, making significant contributions in their chosen fields.

Global research partners and clients include Boeing, Rolls-Royce, Unilever, AstraZeneca, GlaxoSmithKline, Siemens and Airbus, as well as many UK and overseas government agencies and charitable foundations.
