Our work aims to understand the both reasons why motor neurons are vulnerable and what mechanisms contribute to their degeneration.
It is our hope that by understanding these processes we can develop ways in which to protect motor neurons in a variety of pathological contexts.
More specifically, one of our current projects is centred on transcriptional profiling of differentially vulnerable motor neurons. We aim to identify factors which make specific pools of motor neurons selectively resistant in motor neuron disease, and use this knowledge to develop new neuroprotective strategies.
Our lab has a specific interest in the childhood motor neuron disease Spinal Muscular Atrophy. We have ongoing projects looking at where and when pathology starts within the motor neuron. We aim to understand how this limits the effective therapeutic time window, and develop ways to maximize the benefits for patients who are treated after symptoms have started.
An additional area of interest is based on the observation that neonatal axons and synapses degenerate more slowly after injury that they do in adults. We aim to understand why this is, and use this as a model system to better understand the processes of axon degeneration.
