Glia, including oligodendrocytes, Schwann cells, astrocytes and microglia, are the main supporting cells in the mammalian central nervous system (CNS).They perform a variety of different functions and are critical to both neuronal survival and normal function. Our research concentrates on the diverse functions of glial cells and their responses after ocular, spinal and traumatic brain injury as well as investigating their role in diseases such as glaucoma and optic neuritis.
Our research group
The long-term goal of our research group is to understand how glial cells interact with neurons and contributes to normal function, injury-mediated responses and in diseases of the CNS. Our studies have focussed on the responses of glial cells after injury in the eye, spinal cord and the brain.
For example, our work has shown that glial cell activation in the retina correlates with retinal neuronal survival and axon regeneration after optic nerve injury. This work suggests that key axon growth regulatory molecules may be secreted by retinal glia and therefore identification of these molecules will be useful in finding novel molecules to aid axon regeneration after ocular trauma.
In multiple sclerosis (MS), myelin and oligodendrocytes in the brain and spinal cord are the major targets of cell-mediated immune attacks, which results in demyelination and culminates in progressive disability and paralysis in affected patients. To add to this problem, the regenerative capacity of the mammalian CNS is very limited with neuronal repair being curtailed by a wide variety of endogenous inhibitory molecules that culminate in demyelination and eventual loss of function. Currently, MS is untreatable and disease symptoms are poorly managed by current therapies. We are therefore identifying new molecules that will aid remyelination and offer a real therapeutic advantage over currently available drugs.
