Summary

Multiple sclerosis (MS) is a disease in which the body’s immune system mistakenly attacks the protective myelin coating on the nerve cells in the brain and the spinal cord. In most people, the initial stages of their MS are characterised by exacerbations or “relapses” of disease, that involve worsening of symptoms such as limb weakness, blurred painful vision, numbness, or pins and needles. Between relapses the symptoms may dissipate completely; however permanent neurological deficits often remain leading to accumulation of disability. The triggers and mechanisms involved in MS relapse are not clear. Steroids are generally used to treat MS relapses, but these have many side effects, and better treatment options for relapse are needed.

In this 3-year project, Dr Monif’s team will examine the role of a specific immune cell called the monocyte in MS relapses. Monocytes are found in the blood but can enter the brain and are found in large numbers within the injured areas of the brain and spinal cord in MS. There is accumulating evidence that activation of these immune cells can contribute to worsening of MS.

In particular, the project will focus on a protein, the P2X7 receptor (P2X7R) which is found on the surface of monocytes. Previously Dr Monif has found that P2X7R protein is more active in monocytes at the time of MS relapse and that it can activate other brain immune cells. In this study, the team will recruit people from 3 major health centres in Victoria who are having acute MS relapses. Monocytes will be isolated from blood samples and studies conducted to understand the role of P2X7R in MS relapse. The ultimate aim of this work is to developing therapies targeting P2X7R that could potentially halt MS relapse.
