Every breakthrough in neuroscience starts with a question, but understanding what they really mean, and why they matter to patients and families, isn’t always straightforward. 

In this new FutureNeuro series, we delve into the emerging ideas, technologies and discoveries shaping the future of brain research. Each article explores a key scientific concept, explains the research behind it, and shows how discoveries made today could improve diagnosis, treatment and care in the years ahead. 

The series has been developed in collaboration with Laura Bilbao Broch, Science & Health Writer and Clinical Neuroscientist, whose expertise helps translate complex neuroscience into engaging stories for a broad audience. 

Why human brain tissue is transforming MS research? 

How can researchers understand what’s happening inside the brain if they can’t watch the condition unfold directly? For multiple sclerosis (MS), this is one of the biggest challenges researchers face. Much of what we know about MS comes from blood tests, brain scans and studies in laboratory animals, such as mice. Each is useful, but each has limits. 

An MRI scan can show where damage has occurred, but not the fine cellular detail of why. Animal models can mimic some features of MS, but no model fully captures what happens in a human brain living with the condition for decades. 

To understand what MS does at a cellular level, researchers need something far rarer: donated human brain and spinal cord tissue, studied after death with the consent of individuals and their families. This is known as post-mortem research, and it allows researchers to examine the disease in extraordinary detail. They can examine what MS looks like inside the nervous system: which immune cells are present, the condition of myelin (the protective coating around nerve fibres that MS damages), and why the brain’s own repair systems sometimes succeed and sometimes fail. 

Much of this work traces back to the legacy of Professor Dame Ingrid Allen, a pioneering neuropathologist who spent decades building one of the world’s most valuable collections of donated MS brain tissue at Queen’s University Belfast. That legacy lives on today: a gift from her estate helped fund the new Northern Ireland MS Research Hub at Queen’s, launched in 2025 and led by Professor Denise Fitzgerald. 

Fitzgerald, an immunologist, has also secured funding to work with FutureNeuro researchers to investigate a specific question: why the immune system becomes less able to help repair damaged brain tissue as we age, a factor that may explain why MS often gets harder to treat later in life. 

Why does this matter for people living with MS?

Every donated sample helps researchers understand not just what MS damages, but why the brain’s own repair processes falter, and how age affects that capacity to recover. That knowledge could help point toward treatments that don’t just slow the disease but actively support the nervous system’s ability to repair itself, at every stage of a person’s life with MS.
