MS has traditionally been considered to be caused by immune cells from the body entering the brain and attacking myelin, a protective fatty layer that protects our nerve cells in the brain and spinal cord. It is also thought that these immune attacks can damage the cells called oligodendrocytes which produce myelin. However, treatments targeting this immune attack are not always effective, which could possibly suggest that there are other mechanisms contributing towards MS disease progression.

One such possibility is that in MS, there is an increase in chemicals known as reactive oxygen species which are naturally occurring chemicals that are a by-product of normal cellular processes. However, if these processes are not fully controlled, they can cause damage to human cells.  This is referred to as oxidative stress or damage, and can lead to damage to the oligodendrocytes, the cells which form myelin. Oxidative stress has been studied in other neurological conditions such as Alzheimer’s disease and brain trauma, however this has not yet been deeply studied in MS.

This project will investigate the role of oxidative damage in disrupting the blood brain barrier, which may allow immune cells into the brain, and the role of reactive oxygen species in damaging the myelin coating around nerve cells.  This will shed light on whether there are alternative mechanisms in MS, and if there is potential for the development of new therapies that target these mechanisms.

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
