Motor Neurone Disease is a neurodegenerative condition, progressing to paralysis in 1-5 years, and killing 100,000 every year world-wide. We seek to understand its pathogenesis by investigating the underlying mechanisms, which involve different neighbouring cells contributing to the injury of motoneurons. Ongoing work from our laboratory reveals that a population of glial cells, astrocytes, which are intimately associated with motoneurons, profoundly affect their function and existence. We believe that changes to the chemistry and shape of astrocytes initiate a neurotoxic milieu, and that dissection of their roles will provide new clues for management of Motor Neurone Disease.
