ACTRIMS 2017: Putting the microbes in our gut under the microscope

Each person’s gastro-intestinal system is home to trillions of bacteria collectively known as the gut microbiota. These tiny creatures are essential partners in good health, and in less than a decade MS researchers have gone from considering the gut microbiota to be a curiosity to gathering evidence that disruption of the gut’s natural bacterial balance is linked to MS. A powerful method of studying the gut microbiota is to investigate the gut microbiome – the genetic composition of the microbiota. Unresolved questions about the gut microbiome persist, such as: Do people with MS have different microbiome “fingerprints” than people without MS? Does the gut microbiome play a functional role in modifying MS risk and/or disease course? Does the gut microbiome represent a potential therapeutic target in MS? Leaders in the field of MS and gut microbiome research here at ACTRIMS 2017 presented some of the latest findings that tackle these questions.

ACTRIMS 2017: What we know (and don’t know) about dietary factors and MS

The interaction between dietary factors and MS can be a tough nut to crack. On one hand, there is mounting evidence to show that certain nutrients and dietary factors can influence immune regulation and potentially modify the risk of MS or its disease course. On the other hand, dietary factors are notoriously challenging to study in a controlled clinical trial setting; diet trials are difficult to design, results can be influenced by a plethora of other factors (including physical activity, socioeconomic status, certain lifestyle habits, etc.), and individuals often find it challenging to adhere to the intervention plan. Nonetheless, there’s a great deal of high caliber research taking place that’s chipping away at the mysteries surrounding the relationship between certain dietary factors and MS risk and disease course. At this year’s ACTRIMS Forum, several experts in the field presented some of the latest data on this file.

Genetics and environmental/behavioural factors top the agenda at ACTRIMS Forum 2017

Bringing scientists and clinicians together under one roof to share knowledge and forge collaborations is a key stage in moving MS research forward. This year’s Americas Committee for Treatment & Research in Multiple Sclerosis (ACTRIMS) Forum kicks off today in Orlando, Florida. The research team is on site to absorb the latest research and clinical findings in the field and distill the information down into digestible, take-home messages for our readers.

The theme of this year’s forum is “Environmental Factors, Genetics and Epigenetics in MS Susceptibility and Clinical Course”. Not surprisingly, we’ll be hearing a lot about hot topics like interactions between MS and diet, why women are more susceptible to MS than men, the role of viral infections and the gut microbiome in MS, and new insights from in-depth genome-wide analyses to pinpoint genetic variants associated with MS. Many of these topics have grown from niche topics on the fringes of scientific investigation into comprehensive and evolving fields of study in their own right, so we’re looking forward to some fresh and exciting insights into how our genes, our environment, and our behaviours can influence MS.
