Neuronal hyperactivity and neurotrophic factors in motor neuron disease
National Health and Medical Research Council
Using mice with mutant genes causing amyotrophic lateral sclerosis, we will test whether motor neuron hyper-excitability during early development causes excessive synapse and dendrite formation, ultimately leading to neuronal death. We will also test whether activity-dependent secretion of neurotrophic factors and activation of their receptors plays a role in this disease. This will show whether neuronal hyper-activity and neurotrophic factor signaling plays a causal role in this disease.
