In nature, in addition to the 20 amino acids used for making proteins, there are hundreds of plant-derived amino acids, called non-protein amino acids (npAAs). These npAAs are produced to protect plants from being attacked by insects or to block the growth of competing plants. Azetidine-2-carboxylic acid (Aze) is one such npAA that is present in various beets. These plants are used to produce sugar and for feeding beef and dairy cattle.

Due to its structural similarities with the amino acid, proline, Aze from the diet can be mistakenly substituted for proline during the assembly of proteins.". This can cause structural changes to several core proteins required to produce components of the insulating coating of nerves cells, known as myelin. It is possible that such changes could induce the immune system to mistakenly attack the myelin.

In this project, samples of brain tissue from people with MS and people without MS obtained from the MS Australia Brain Bank and the Victorian Brain Bank will be used to assess if Aze is mistakenly added into myelin, and whether there are differences in the amount of Aze mistakenly added in different MS subtypes.

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.

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
