MS linked to genes tied to more Epstein-Barr virus
Key Takeaway
People with MS carried more inherited gene patterns linked to higher levels of Epstein-Barr virus in blood cells.
What They Found
Researchers used blood samples to look for signs of Epstein-Barr virus (the virus that causes mono). These signs appeared in about 16% of one group and about 22% of the other. Finding the signs was linked to higher levels of the virus in blood cells. The signs were also linked to smoking, HIV (a virus that weakens the immune system), and medicines that suppress the immune system. People with MS carried more inherited gene patterns linked to these signs, especially one pattern tied to how the body handles infection.
Who Should Care and Why
The study examined people in two large health databases, including people with MS. It looked at why levels of Epstein-Barr virus differ between people. Epstein-Barr virus remains in the body after infection. The researchers found inherited patterns linked to signs of more virus in blood cells. People with MS were one group examined for these patterns.
Important Considerations
The researchers analyzed stored blood data from 822,438 people in an observational study. You cannot tell from these findings whether the gene patterns caused MS. The abstract does not say whether people with MS had higher virus levels than people without MS.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Nature often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
