On April 9, 2022, I reached 3,000 miles on my 15,000 mile fundraiser to find a cure for Multiple Sclerosis (MS). After reaching 10,000 miles in 2021, there was only one obvious choice- ride farther than before. I set the new distance goal at 15,000 because it’s difficult to achieve- that’s the point. Cycling 15,000 miles in a single year is admittedly insane but raising money and awareness for MS is the real goal. Please donate to this worthwhile cause HERE.

Researchers Find Potential Mechanism for How Epstein-Barr Virus May Trigger Immune Attacks in MS
January 27, 2022
Investigators at Stanford University and their collaborators have identified a mechanism for how the Epstein-Barr virus (EBV), a known risk factor for multiple sclerosis, may prompt the immune system to attack brain cells to trigger MS. In a study published in Nature, antibodies derived from cells in the spinal fluid were shown to recognize and bind to a component of EBV and also shown to recognize and bind to a similar molecule on brain cells that have been implicated in MS. This suggests that the molecule on brain cells mimics the structure of the EBV component and can set off an autoimmune process.
This study follows a recent announcement of new proof that EBV infection occurs in advance of the onset of MS and acts with other risk factors to cause the disease. Both studies provide a firm rationale for developing therapies and vaccines to thwart EBV and potentially stop MS or prevent its onset.
- EBV: The Epstein-Barr virus is spread primarily through contact with infected saliva. It is very common, and most people are infected by it, generally without harm, in childhood. In adolescence and adulthood, it can cause infectious mononucleosis, a disease that increases the risk of later developing MS. The virus stays in the body throughout a person’s lifetime, and has been linked to certain cancers and autoimmune diseases. There is currently no treatment that can eliminate the virus from a person’s system.
Details of the Study
- Through a series of steps, researchers led by Dr. William Robinson found evidence that up to one-fourth of people with MS had antibodies circulating in the blood and spinal fluid that recognized and bound to both a product of the EBV virus and a component of the brain cells that produce myelin, the nerve-insulating sheath that is a key target of immune attacks and destruction in MS.
- This “cross-reactivity” means that when the immune system is doing its job to try to fight EBV, it may also attack myelin-making cells. The team further evaluated this scenario by introducing the segment of EBV into mice with an MS-like disease, which made it worse.
- This study was supported in part by a special initiative in which the JDRF, Lupus Research Alliance, and National MS Society joined forces to identify common mechanisms of autoimmunity.
- This and other studies provide the rationale for developing therapies and vaccines that target EBV. Importantly, this study suggests that any EBV vaccine to be developed should not include the particular EBV component (EBNA1) that might cross-react and cause an autoimmune reaction to myelin-making cells.
World MS Day: May 30, 2022
World MS Day unites individuals and organizations from around the world to raise awareness and move us closer to a world free of MS. The theme for 2022 will be called ‘‘I Connect, We Connect’’ (#MSConnections) and the theme is building community connection, self-connection and connections to quality care.
In 2009, the Multiple Sclerosis International Federation (MSIF) and its members initiated the first World MS Day. Together we have reached hundreds of thousands of people around the world, with a campaign focusing on a different theme each year.
MSIF provides a toolkit of free resources to help everyone to take part in World MS Day. Anyone can use these tools, or make their own, to create positive change in the lives of more than 2.3 million people around the world. Visit worldmsday.org
