Myelin is the insulating sheath wrapping around many axons in the peripheral (PNS) and central nervous system (CNS). It is essential for the rapid and efficient transmission of neural signals along the axons, and provides metabolic and trophic support to the axons that it surrounds. Human demyelinating diseases, such as Multiple Sclerosis (MS), have a devastating impact on quality of life. It is the failure of the nervous system to repair myelin after a demyelinating insult that leads to disease progression and increasing disability. In addition, myelin damage is a common pathological feature of many neurodegenerateive diseases. However, there is currently an incomplete understanding of the molecular and cellular events that initiate, promote and maintain the interactions between neurons and glial cells that are vital for myelination in both the PNS and CNS.

Our laboratory is particularly interested in understanding the molecular cues that are vital for myelination during development, and myelin repair after injury as well as developing new therapeutics for promoting repair after myelin injury. We use a variety of molecular, cellular, biochemical, genetic and confocal imaging techniques in combination with behavioural analyses and animal models of demyelinating disease to investigate these events.
