MS study probes how gut reactions influence risk of disease
17 June 2016
Researchers will analyse bacteria living in the digestive systems of people with MS and compare them with samples from people who do not have the condition.
The findings may help scientists understand how these bacteria can affect the immune system, and the impact this may have in determining the development in MS.
Bacteria in the gut play a crucial role in helping to digest food and fight off infection. Sometimes, if the balance of bacteria is disturbed it can cause disease. The study will use DNA sequencing technology to identify which bacteria populations are more or less - abundant in people with MS.
Researchers at the University of Edinburgh are recruiting 500 co-habitating pairs from across Scotland. People with MS will be invited in the study along another member of their household.
By studing bacteria in people who live together, scientists hope to pinpoint the role of shared environmental influences such as eating habits, smoking and lifestyle.
The international trial - being conducted in the US, UK and Argentina - is being led by the University of California. It has been funded by philanthropic donation.
"While we understand a lot about the genetic factors of MS, exactly how the environment influences our immune system has been difficult to pinpoint. Human gut bacteria are placed at the interface between our immune system and the outside environment, and so provide ideal material to address this question." Dr Peter Connick, Study leader.
Participant will be asked to give a blood and stool sample and to complete a detailed questionnaire about their eating habits and home environment. People interested in joining the study can find more details by clicking here
