Dr Éanna Fennell of University College Cork has secured a €2.1 million Wellcome Trust grant to investigate why women develop multiple sclerosis at up to three times the rate of men, focusing on how the X chromosome influences immune responses to the Epstein-Barr virus.
In Plain English: The Clinical Takeaway
- The Gender Disparity: Women are up to three times more likely than men to develop multiple sclerosis, yet the biological reasons remain poorly understood.
- The Genetic Hypothesis: This upcoming study will test whether the X chromosome contributes to this disparity by shaping how the immune system reacts to the Epstein-Barr virus.
- Cellular Testing: Scientists will analyze immune cells from patients and use genetic engineering on laboratory-grown cells to map these underlying drivers.
The Wellcome Trust Grant and University College Cork Research
The Wellcome Trust awarded the €2.1 million funding to support an ambitious research program designed to deliver significant shifts in understanding of human life, health and wellbeing. Dr Fennell, working within the Department of Pathology at UCC’s School of Medicine, will lead the investigation into the cellular mechanisms driving the condition. Across Ireland and the UK, an estimated 160,000 individuals manage multiple sclerosis, a condition wherein the immune system harms the protective sheath encasing nerve fibers in the spinal cord and brain.
Prof John F. Cryan, UCC Vice President for Research and Innovation, noted the prestige of the award and the potential impact of the project. “His work will combine research in genetics and immunology to give a better understanding of MS, provide a new framework for understanding sex differences in MS and lead to new pathways that can be targeted for more effective therapeutic strategies,” Prof Cryan stated.
Cellular Mechanisms and Epstein-Barr Virus Link
Multiple sclerosis damages the protective coating surrounding nerves in the brain and spinal cord, which can significantly affect quality of life and reduce life expectancy. The disease has a strong link to the Epstein-Barr virus, but researchers still need to clarify why women are up to three times more likely than men to develop MS.
Researchers will examine immune cells from people with MS. By deploying genetic engineering techniques to introduce or correct specific genetic differences in laboratory-grown cells, the team aims to isolate the precise biological pathways at play. “By bringing together genetics, immunology and sophisticated models, we hope to better understand the mechanisms driving the disease and identify new opportunities for therapeutic intervention,” Dr Fennell stated.

Pathways Toward Future Therapeutic Intervention
Wellcome Trust Awards are granted to scientists with the potential to become international research leaders. By establishing a clearer framework around biological sex differences in autoimmune disorders, the UCC study aims to lay the groundwork for more precise treatments. The project moves forward as researchers continue striving to translate fundamental genetic discoveries into actionable clinical interventions.
