Summary
N-type voltage-gated calcium channels (VGCCs) are membrane proteins involved in neurotransmission and play a major role in pain. VGCCs are a well-established target for the development of analgesics. Our recent research identified that VGCCs can be inhibited by ?-conotoxins from the venom of marine snails by targeting ?-aminobutyric acid receptors in sensory neurons. We will characterize this novel form of modulation of VGCCs by ?-conotoxins and define the pathways that lead to VGCC inhibition.
The Involvement Of The Kynurenine Pathway In Blood Brain Barrier Disruption And Its Relevance For Neuroinflammatory Diseases

Summary
We aim to study the involvement of molecules deriving from the degradation of the essential amino acid tryptophan on the breakdown of the ñblood-brain barrierî (the cellular wall separating blood and brain) that is observed in several major brain diseases. Using specific drugs blocking the production or the effects of these toxic compounds we expect to be able to preserve the integrity of the blood brain barrier and so to limit brain inflammation and neuronal loss.
Controlling Neuroinflammation In Alzheimer's Disease

Summary
Alzheimer’s disease (AD) is the most common neurodegenerative disorder worldwide, with 269,000 Australians currently diagnosed with AD and is expected to soar to about 981,000 by 2050. AD accounts for greater than 60% of all cases of dementia. This grant investigates the role that neuroinflammation plays in the progression and exacerbation of AD and will identify new therapeutic strategies to combat this insidious disease.
