Multiple sclerosis (MS) is a chronic autoimmune disorder that attacks the central nervous system. For years, Epstein-Barr virus (EBV) has been strongly linked to MS, as nearly every person diagnosed with the condition shows evidence of past EBV infection. For example, a 2022 study analyzed millions of U.S. military recruits and found that getting infected with EBV increased a person’s risk of developing MS 32-fold.

But exactly how EBV is linked to the abnormal immune response seen in MS has remained unclear until now.

In a study published in Science Translational Medicine, scientists descr...

Experimental Drug Speeds up Myelin Repair, Restoring Vision in Mice

Researchers at the University of Colorado Anschutz Medical Campus have found a promising drug candidate that could help restore vision in individuals with multiple sclerosis (MS) and other neurological conditions that damage neurons.

The study was published this week in the journal Nature Communications.

The drug, LL-341070, enhances the brain’s ability to repair damaged myelin— the protective sheath around nerve fibers. Damage to myelin is a hallmark of diseases like MS, as well as a natural consequence of aging, often resulting in vision loss, loss of motor skills, and cognitive decline.

The research, focused on vision, demonstrated that while the brain has some ability to repair itself when myelin is damaged, the process can be slow and i...

Epstein-Barr Virus and Brain Cross-reactivity: Possible mechanism for Multiple Sclerosis detected

The role that Epstein-Barr virus (EBV) plays in the development of multiple sclerosis (MS) may be caused by a higher level of cross-reactivity, where the body’s immune system binds to the wrong target, than previously thought.

In a new study published in PLOS Pathogens, researchers looked at blood samples from people with MS, as well as healthy people infected with EBV and people recovering from glandular fever caused by recent EBV infection.

The study investigated how the immune system deals with EBV infection as part of worldwide efforts to understand how this common virus can lead to the development of multiple sclerosis, following 20 years of mounting evidence showing a...

Researcher takes another step toward discovering how a Brain Molecule could Halt MS

Fractalkine appears to trigger repair of brain damage caused by the disease. A University of Alberta researcher is one step closer to demonstrating the potential of a brain molecule called fractalkine to halt and even reverse the effects of multiple sclerosis and other neurodegenerative diseases.

Multiple sclerosis is an autoimmune disease in which the myelin, or fatty lining of nerve cells, is eroded, leading to nerve damage and slower signalling between the brain and the body. MS symptoms range from blurred vision to complete paralysis, and while there are treatments, the causes are not fully understood and nothing exists to reverse the disease process. More than 90,000 Canadians live with MS, according to the MS Society.

In new research published in Stem Cell Reports, Anastas...
