Summary
Persistent exposure to stressful events can produce serious and lasting disturbances in cognitive function. Our research group has recently identified that microglia may play a very significant role in these disturbances. The studies to be undertaken in this proposal will provide fundamental knowledge on how microglia contribute to neuronal plasticity, and how microglia via their effects on neurons regulate complex cognitive behaviour.
Neuron To Glia Signalling: Learning How Synaptic Signalling Can Promote CNS Remyelination

Funding Amount
$609,650.00
Summary
An immature cell type in the brain, known as the oligodendrocytes progenitor cell (OPC), receives direct electrical communication from neurons. This communication regulates the behavior of the OPC, affecting its ability to divide and generate new brain cells. This project will identify the signaling molecules that guide the OPC to for this specialized contact with the nerve cell. Understanding this communication has important implications for the treatment of Multiple Sclerosis.
The Role Of Innate Immune Memory In The Transition From Acute To Chronic Pain

Funding Amount
$331,440.00
Summary
Chronic pain costs Australians more than $34 billion annually and is the 3rd highest Australian disease burden. It has long been thought to be a disease of the wiring of the brain. This project aims to challenge this long held belief by examining the impact of the immune system in creating chronic pain. Such work promises to provide new and better ways to prevent chronic pain, which will improve & maintain good health for all Australians.
Properties And Functions Of Reactive Astrocytes And Their Role In Neurological Disease

Summary
I am a developmental neuroscientist interested in the way alterations to normal brain development affect neuronal function later in life. I intend to investigate this by studying astrocytes – the cells that support and nourish brain nerve cells. In some diseases these astrocytes become stressed and instead of aiding the brain, set about destroying it. A better understanding of their action during development and disease may enable improved interventions for the treatment of many brain disorders.
To Understand The Role Of The Plasminogen Activating And Matrix Metalloproteinase Systems In Traumatic Brain Injury

Summary
Tissue-type plasminogen activator (t-PA) is known for its role as a clot dissolving protein. It is present in the brain and following traumatic brain injury (TBI), it can worse brain cell damage. We have established a mouse model of TBI . We will compare brain damage in mice that are deficient in or have high amounts of t-PA. We will also determine whether the recovery rate post-TBI can be improved using specific t-PA blockers. This project may provide new therapies for TBI.
Structure-based Drug Design For Neuroprotection From Traditional Chinese Medicine

Summary
In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative di ....In the proposed research, three novo approaches for drug discovery will be explored: 1) The important neurodegenerative disease relevant protein JNK3 crystals will be used as the probe to fish out the potential inhibitors from Traditional Chinese Medicine (TCM); 2) Instead of individual drug components, the mixture of TCM will be used directly; 3) The composition of a TCM library are not randomly chosen but have been used in China for hundreds to thousands of years in curing neurodegenerative disease.Read moreRead less
A Novel Mechanism For Therapeutically Modulating Neurotransmitter-activated Ion Channels
Funder

Funding Amount
$667,529.00
Summary
This project aims to elucidate the mechanisms by which macrocyclic lactones bind to brain ion channel receptors. This will reveal fundamental new insights into the operation of these receptors and will have important implications for the design of novel treatments for a variety of central nervous system disorders.
Inhibitory Neurotransmitter Receptors As Therapeutic Targets For Chronic Pain And Anxiety Disorders

Funding Amount
$763,409.00
Summary
There are currently few effective long-term treatments for chronic pain and anxiety disorders. Here we propose to develop innovative therapies for both of these debilitating neurological disorders. In addition, we plan to improve our current understanding of how these disorders occur in the first place. This may identify novel potential therapeutic strategies for treating pain, anxiety and a host of other neurological disorders.
Understanding how the multiple roles of olfactory ensheathing cells guide the growth and regeneration of olfactory axons. The outcomes of this project will increase the understanding of how nerve cells develop and regenerate after injury. The research outcomes and the development of new innovative methodologies as part of the project will be of high significance for the neuroscience research community both within Australia and overseas.

The outcomes of this project will increase the understanding of how nerve cells develop and regenerate after injury. The research outcomes and the development of new innovative methodologies as part of the project will be of high significance for the neuroscience research community both within Australia and overseas. The findings will also pave the way for the development of novel therapies that promote neuronal regeneration relevant for disorders such as spinal cord injury and Alzheimer's disease, which constitute a large socio-economic burden in Australia. Currently, 400 people contract spinal cord injury every year, corresponding to an annual cost of $1 billion, and more than 500 000 aging people suffer from Alzheimer's disease.Read moreRead less
