MS is characterised by immune cells attacking and destroying myelin, the insulating component of nerve cells in the central nervous system. MS is more common in western countries compared to Asia and Africa and this is due to genetic differences and environmental factors, such as diet. One way diet may be playing a role is by shaping the bacteria in our guts. There is now strong evidence that gut bacteria play a critical role in regulating immune responses in MS and other diseases. Butyrate is a molecule produced by gut bacteria and the amount produced is dependent on a person’s diet. Butyrate changes the way immune cells function by sticking to a protein on their surface called GPR109A.

Associate Professor Laurence Macia and her team have shown that intermittent fasting is very effective in improving symptoms in a laboratory model of MS. Preliminary results have also shown that levels of butyrate increase with intermittent fasting. Associate Professor Macia and her team plan to study whether the beneficial effects they see in their models of MS are due to butyrate and GPR109A interacting together.

Stages of the research process

Fundamental laboratory

Laboratory research that investigates scientific theories behind the possible causes, disease progression, ways to diagnose and better treat MS.

Lab to clinic timeline: 10+ years

Research that builds on fundamental scientific research to develop new therapies, medical procedures or diagnostics and advances it closer to the clinic.

Lab to clinic timeline: 5+ years
Clinical Studies
and Clinical Trials

Clinical research is the culmination of fundamental and translational research turning those research discoveries into treatments and interventions for people with MS.

Lab to clinic timeline: 1-5 years
