Elevated levels of two bacterial strains from the Lachnospiraceae family in the gut may be a key risk factor for multiple sclerosis (MS), according to a study. The study, “Multiple sclerosis and gut microbiota: Lachnospiraceae from the ileum of MS twins trigger MS-like disease in germfree…

Interactions between the body’s immune system and bacteria that live in the digestive tract — essentially, a person’s gut — become disrupted in multiple sclerosis (MS), a new study by U.S. researchers found. The human intestines are home to billions of bacteria and other microorganisms, collectively known as the…

A ketogenic diet — a very low-carbohydrate, high-fat eating plan called a keto diet for short — was able to lessen the severity of multiple sclerosis (MS) in mouse models by modulating the activity of gut bacteria and their metabolites, a new study shows. The findings suggest that…

Supplements of indole 3-lactate (ILA), a molecule made by gut bacteria, significantly reduced disease severity and promoted myelin repair in mouse models of multiple sclerosis (MS). That’s according to new findings presented by Larissa Jank, PhD, a postdoctoral researcher at Johns Hopkins University, at the Americas Committee for Treatment…

Pro-inflammatory immune cells that can target the brain may be activated in a specific region of the intestine by certain gut bacteria before migrating to the brain, according to a new study done in mice. Researchers say these findings provide a proof of concept for how some immune cells may…

A bacterial toxin in the gut — specifically, the epsilon toxin produced by Clostridium perfringens bacteria in the intestinal tract — may be a key environmental driver of multiple sclerosis (MS), according to a recent study. After finding the toxin at a higher abundance in the fecal samples of MS…

Gut Bacteria Are Altered in MS, Linked to Disease Progression Several studies have indicated that the composition of gut bacteria in people with MS is different from that of healthy people. But earlier studies didn’t take into account environmental factors, such as where the study subjects lived or what…

The composition of bacteria in the gut is altered in multiple sclerosis (MS) patients compared with healthy people in the same household, a new study reports. That bacterial composition is affected by disease-modifying therapies and seems to be associated with disease severity. These findings could aid in developing…

A relationship between meat consumption and how it affects gut bacteria, immune cell profiles, and metabolism was identified in people with relapsing-remitting multiple sclerosis (RRMS) participating in a small study. Specifically, a diet rich in meat was associated with a decrease in Bacteriodes thetaiotaomicron, a common gut bacteria that works…

Epstein-Barr Virus May be Leading Cause of MS, Raising Risk by 32 Times Several studies over the past few years have suggested a link between the Epstein-Barr virus (EBV) and multiple sclerosis (MS), but this one is huge, both in the number of participants and in the length…

People with multiple sclerosis (MS) have high levels of toxic compounds made by gut bacteria in the fluid around their brain and spinal cord, a study found. “This work not only furthers our understanding of the role of gut-brain communication in neurodegenerative disease progression, but also provides a potential…

Isoflavone-rich diets boost gut health and lessen multiple sclerosis (MS) severity, a new study in mice suggests. In the study, mice with MS that were fed a diet rich in isoflavone — a plant-based compound — developed diverse and abundant gut bacteria, particularly isoflavone-digesting bacteria, which produced compounds that…

A short-chain fatty acid produced by gut bacteria helps to counteract inflammatory responses in multiple sclerosis (MS) by promoting greater numbers of regulatory immune cells, a study reports. But the bacterial composition of the gut (its microbiome) of MS patients is deficient in bacteria that produce this acid —…

Stress-induced changes in gut bacteria, or gut microbiota, may play a significant part in the possible link between exposure to stress and the risk of autoimmune disorders such as multiple sclerosis (MS), a mouse research study says. In the study “…

Bacteria that reside in human gut may trigger autoimmune reactions by producing human-like proteins that mimic a naturally occurring and crucial cell protein. Researchers at Queen’s University Belfast in Ireland report that patients with autoimmune disorders — such as multiple sclerosis (MS), rheumatoid arthritis, and ulcerative colitis — have…

Stanford Researchers Open Medical Cannabis Company with Oral Therapy for MS Pain, Spasticity as Initial Goal Let’s be clear up front. There’s no indication that you’ll be able to buy a cannabis pill from this company anytime soon — or ever. The company’s website says that testing…

Lately, much of my work has been focused on the relationship between the gut and MS. As I experience ongoing gut issues, I need to learn how to advocate for myself by learning as much as I can about gut bacteria and finding the right…

Pilot Study Is Testing Whether Mediterranean Diet Can Help MS Patients There’s been a good deal of news recently about the possibility that bacteria in our stomachs have an impact on our MS. There’s also been talk, for a long time, about whether certain diets can improve…

Propionic acid supplements alter the composition and behavior of immune cells in multiple sclerosis (MS) patients — likely by changing the composition of gut bacteria, according to Alexander Duscha from Ruhr University Bochum in Bochum, Germany. The finding, presented Wednesday at the 7th Joint ECTRIMS-ACTRIMS Meeting running in Paris…

Probiotics Consumption May Improve Certain Disease Parameters in MS Patients, Study Suggests Probiotics (bacteria that help move food through your gut) have been used for years to help treat stomach disorders such as irritable bowel syndrome, inflammatory bowel disease, and some types of diarrhea. More recently, researchers have…

University of California at San Francisco Recruiting MS Patients for Gut Bacteria Study Last year, a Harvard study reported significant differences between bacteria that MS patients have in their bellies and that found in those who don’t have MS. If that bacteria is treated, those MS-related changes might…

University of California medical school researchers are looking for multiple sclerosis patients who want to participate in an international study of the bacteria that live in our gut. The University of California at San Francisco team decided to study the gut microbiome after recent evidence suggested that it is critical in…

The past year has taken its toll on my digestive system. I’ve experienced alarming amounts of pain, bloating, diarrhea, and more fatigue than I normally experience from MS. All of these issues caused great stress both emotionally and physically, so it was no surprise when my…

Immune cells, believed to drive autoimmunity, are selectively increased in the gut of patients with multiple sclerosis (MS), along with lower numbers of cells controlling inflammation, suggesting that immune processes in the gut impact MS disease mechanisms. The study, “The role of gut immunity in multiple sclerosis patients,”…

Gut bacteria and health have been topics of considerable scientific speculation in recent years, and the field of multiple sclerosis (MS) research is no exception. But what do we really know about MS and our intestinal inhabitants? A review, “Emerging Concepts on the Gut Microbiome and Multiple Sclerosis,” published in…

Researchers at the Center of Excellence for Myelin Repair, a part of Mount Sinai, reported that gut bacteria produce compounds that were seen to affect the myelin content in mice and cause social avoidance behaviors. Study results indicated that targeting gut bacteria, or the gut metabolites, might help in treating neuropsychiatric disorders or complications, such as those…

Results from a recent study published in the journal Immunity indicate that dietary fat has an influence in the duration and severity of autoimmune flare-ups in a mouse model of multiple sclerosis. The team of researchers also showed that adjusting the length of the fatty acids consumed by…
