Infection with the common Epstein-Barr virus and MS

Epstein-Barr Virus May Increase Risk of MS, Other Diseases, Study Reports

Epstein-Barr is extremely widespread. More than 90 percent of the population of the U.S. and other developed nations become infected with by age 20. The virus remains with infected people throughout their lives.

Mononucleosis is the most frequently seen ailment caused by EBV. Mono is nicknamed the “kissing disease” because the virus spreads mainly through saliva.

Previous research linked Epstein-Barr to lupus and certain cancers of the lymphatic system. Regarding the association with lupus, work by John Harley, MD, the current study’s lead author, demonstrated that the immune response to EBV may cause the disease. It also showed that children with lupus were almost always infected with the virus.

When responding to viruses and bacteria, the body uses B-cells to produce antibodies that will fight the foreign agents. But in Epstein-Barr infections, the virus invades and takes control of B-cells.

Scientists now showed that EBV achieves this through tiny proteins called transcription factors, which critically regulate gene expression — the process that generates proteins from DNA.

Specifically, the research revealed that the virus-derived EBNA2 transcription factor binds to several spots in the human genome that are linked to these seven diseases.

“Using genomic methods that were not available 10 years ago, it appears that components made by the virus interact with human DNA in the places where the genetic risk of disease is increased,” Harley said in a press release. “And not just for lupus, but all these other diseases, too.”

“This discovery is probably fundamental enough that it will spur many other scientists around the world to reconsider this virus in these disorders,” Harley added. “As a consequence, and assuming that others can replicate our findings, that could lead to therapies, ways of prevention, and ways of anticipating disease that don’t now exist.”

Despite its prevalence, there is still no existing vaccine preventing the Epstein-Barr infection.

“I think we’ve come up with a really strong rationale for encouraging people to come up with more of an effort,” said Leah Kottyan, one of the study’s senior authors. “Some EBV vaccines are under development. I think this study might well encourage them to push forward faster and with rededicated effort.”

The research also indicates that these seven diseases share a common set of abnormal transcription factors, all affected by EBNA2.

“Normally, we think of the transcription factors that regulate human gene expression as being human,” Kottyan said. “But in this case, when this virus infects cells, the virus makes its own transcription factors, and those sit on the human genome at lupus risk variants (and at the variants for other diseases) and that’s what we suspect is increasing risk for the disease.”

Future studies are needed to clarify how many cases of either of the seven diseases may be explained by prior EBV infection.

“In lupus and MS, for example, the virus could account for a large percentage of those cases. We do not have a sense of the proportion in which the virus could be important in the other EBNA2-associated diseases,” Harley said.

Finding specific transcription factors associated with Epstein-Barr infections may ultimately lead to new therapies for multiple diseases.

“This same cast of characters is a villain in multiple immune-related diseases,” said Matthew Weirauch, PhD, also a senior author of the study. “They’re playing that role through different ways, and doing it at different places in your genome, but it’s the same sinister characters. So if we could develop therapies to stop them from doing this, then it would help multiple diseases.”

Beyond EBV, the investigators explored links between all 1,600 known transcription factors and gene variants associated with over 200 diseases. Results revealed correlations in 94 disorders.

“Our study has uncovered potential leads for many other diseases, including breast cancer,” Harley said. “We cannot possibly follow up on all of these, but we are hoping that other scientists will.”

“As new genetic association and [transcription factor] binding data are collected, approaches such as this will undoubtedly identify further disease mechanisms,” the researchers wrote.

The team decided to make public the software tools used to track genetic changes and activity of the transcription factors.

“We are going to great lengths to not only make the computer code available, but all of the data and all of the results,” Weirauch said. “We think it’s an interesting approach that could have implications for many diseases, so we’re contacting experts on the various diseases and sharing the results and seeing if they want to collaborate to follow-up on them.”

    I find this very interesting. I had mono and now have IBD. I have also had labs positive for Lupus and RA. I hope more research is done on this.

  2. Amy says:

    Is there any way for researchers such as yourselves to take my DNA and test it for any known diseases like you’ve discussed? Lupus, rheumatoid arthritis, no lesions present for ms (but sm symptomatic), lyme all are negative;

    I’ve been diagnosed with small fiber nueropathy, Vitamin D deficiency, ehlers danlos (but no genetic testing done). I’m categorized with “Fibromyalgia”!

    I have little energy, fatigue, constant pain, bone & joint pain, facial bone pain, sinus pain, ear pain- always feel full, legs feel heavy – like full of sand, my muscles burn, developed an asthma (get a horrible smell once in a while when I breathe)

    I feel like with all the science out there – someone should be able to help me get my life back.

    My life changed when I was 27. I was put on ciproflaxin for recurring urinary tract infections & I started losing functions in my hands, couldn’t get out of bed, loss control of my bladder.

    I’d give anything to have a bit of my life back!

    • I so wish I had some answers for you… I just wanted to say that your symptoms sound very much like mine. Have you had testing from Lyme and other tick-bourne diseases through IGeneX? So hoping you get some answers soon and that you can begin to feel better!

    I was dx with EBV in 2008 after a lymphnode in my neck was removed. Since 2002, I suffered all symptoms of MS. Went through all gruelling tests three times and still inconclusive results. I am now 52 and my symptoms are worse. No dx and no meds, just a “wait and see” comment by my 7th neuro. I wish there was a test that will dx MS on the spot. Waiting and wasting away isn’t fair.

  4. Tammy Barrett says:

    Thanks for info, I had mono with hepititis at 17 and was hospitalized for 7 days. And at the age of 38 stopped having periods only to find out that I had Hypo thyroidism, and never had another period. In my early forties I had constant sinus infection and ear aches had to have sinus surgery and tubes in my ears. Afew years after that I had to have my gallbladder removed because of pain. In 2014 found out I had rumitorid arithis. Then in 2015 I was having heart palpitations and breathing issues only to find out that my mitral valve and ruptured with severe regurgitation, and had to have open heart surgery. Now it’s 2018 and I still feel like crap most of the time, when I do to much I am down for afew days just exhausted. I offen feel like there is something more to all of these health issues this may explain it all. I have always been very full of energy and never smoked hardley drink and in pretty good shape. Just wondering what the years to come will be like for me doesn’t look to good. Any help would be greatly appreciated.

    Hi all, I totally sympathize with all of you suffering from chronic illness and autoimmune disease. I am a nurse who suffered from various debilitating chronic illnesses (endometriosis, migraines, thyroid, leaky gut) for many years until I took my health into my own hands. I have been studying chronic/mystery illnesses for many years and learned to nurse myself back to health. I recently stumbled upon the work of Anthony Williams, the Medical Medium. He is very knowledgeable of Epstein Barr Virus and how it, along with other viruses/bacteria/parasites relate to many other diseases. I highly recommend reading his books. Good luck to all of you who suffer from the pain (physical and emotional), anguish, and debilitating effects of chronic illness.

    I’ve had MS 35 years. I grew up at a northern latitude, NYC, which has statistical significance. I had severe mono when I was in elementary school, almost died from it. That’s been implicated scientifically, too. But I never swapped spit or any other fluids, no kissing, no hugging. I was taught to never share toothbrushes, combs, cookies, sandwiches, beverages, candy, clothing, other foods, or anything else, and never did. Don’t know how I contracted it. It may be that my family is the silent carrier, like Typhoid Mary.

    What I do know, is that on top of having to cope with the disease as an adult, there was a worse trauma: the local doctors in Albuquerque, NM profiled me by gender and ethnicity and decided I was just a hysterical conversion reaction, and that I could walk and defecate/pee if I really wanted to. That has left me with PTSD about the medical community, which is sometimes worse than the disease. It would be hard now for them to gaslight me, ever again. I had to spend my life savings to go alone to the Mayo in MN, to get my diagnosis. I’ve been in the hole ever since, financially.

    Also, interestingly, I’ve read the EB virus can lead to certain cancers, and my mother, father and sister all died of cancer, the females from breast, my father from non-Hodgkin’s lymphoma, and there was also cancer in both paternal grandparents, a maternal aunt and uncle. It could be genetic predisposition or mutation… it could be environment… it could be measles or chicken pox or mumps, or other microorganisms… it could even be from living in a place that’s actually too clean and sterile, so the patient overreacts and attacks themselves when confronted by common disease organisms. There was a study about the Trobriander Island natives who historically had no MS, who then had an epidemic outbreak of MS after WW II, after the British left, it suggested contagion might be a factor, but it didn’t consider other factors the British Introduced: stress, cigarettes, alcohol, sexually transmitted diseases, toxins, childhood diseases they never had, even the common cold, dietary changes, western drugs with side effects, vaccinations. But there are so many other variables: my family smoked, ate meat and cold cuts, ate convenience foods loaded with preservatives and additives, the women dyed their hair and wore cosmetics on their skin, used synthetic perfumes, fragrances and nail polish… they were all depressed, which also can immunocompromise. One published article said that lifestyle can impact up to 90% whether you get cancer or not, and my lifestyle as an adult is very different and much healthier than theirs. Who knows. Shrug.

    What I do know, is that most MS and other catastrophic illness patients go through a potentially expensive phase where they waste a lot of time, worry and money grasping at remote or bizarre causes, and they latch onto unproven and silly fad theories and cures, religious predictions, odd diets, mystical weird authorities, and remote causes… and after a while, one gets on with life, takes better care of oneself, and works with what one has left, and what has been scientifically proven. Charlatans have always preyed upon the weak and vulnerable.
