Therapeutic Modulation of Inflammation in Neurodegenerative Disease
The complement factors C3a and C5a are a potent inflammatory and immunomodulatory molecules. Inflammation is increasingly implicated in the progression of neurodegenerative disease. Our laboratory is investigating the effects of C3a and C5a in several models of neurodegenerative disease, including Motor Neuron disease (ALS), Parkinson's disease, and Huntington's disease, by using a specific C3a and C5a receptor therapeutics, and novel transgenic mice and tools developed by our group. We are also investigating novel modulators of the innate immune system as potential new targets to combat neuroinflammation in these diseases.
Complement anaphylatoxin agonists and antagonists as pharmacological modulators of immunopathology
We are collaborating with local and international groups to develop and test novel drugs which target the inflammatory process induced by complement system activation. We are also working closely with clinicians at the Royal Brisbane & Women's Hospital, Brisbane, who focus on neurodegenerative and inflammatory diseases, to help translate our knowledge into the clinic, for the benefit of patients.
Role of the innate immune complement system in the development of the brain
We have found that components of the innate immune system are essential for aspects of neural development. Specific inhibition of the complement system impairs neurogenesis and brain development, and when combined with folate deficiency leads to drastic neural tube defects in mice. We are exploring the mechanisms by which this system helps to develop the brain, which will provide clues to what happens when things go wrong - and potential ways to combat this.
