Optimising Combinations Of Calcium Channel Inhibitors For Treatment Of Secondary Degeneration After Neurotrauma

Funding Amount
$679,772.00
Summary
Traumatic injury to the central nervous system is made worse by damage that spreads away from the initial point of impact. Excess calcium entering cells is a key contributor to spreading damage but treatment with single calcium channel inhibitors has been disappointing. We will use combinations of calcium channel inhibitors to block multiple calcium channels and ensure the optimised combination is effective in clinically relevant models of neurotrauma.
Investigating Genetic Determinants Of Absence Epilepsy In A Polygenic Rat Model

Summary
The underlying genetic causes of idiopathic generalised epilepsies (IGE) are still largely unknown. In an animal model of IGE we have discovered novel genetic abnormalities an ion channel. This proposal will build upon these novel findings to examine the role these abnormalities have in determining the absence epilepsy phenotype and this work has the potential to provide vital information regarding the mechanisms by which this gene contributes to an IGE seizure phenotype.
Repair Of The Nigrostriatal Pathway By Phenotype Shift Of Dopamine Neurones

Summary
Repairing the injured brain will depend on developing new cells that can form the correct cell type, make the right connections and be incorporated into normal brain circuitry. We have found that dopamine cells, which are lost in Parkinson's Disease, are being renewed in the adult rodent brain. This study is directed at finding factors that control this process and to exploit these factors therapeutically. We provide evidence that this can be used to treat Parkinson's Disease.
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.
Targeted Nanoparticles To Deliver Combinations Of Calcium Channel Inhibitors To Prevent Myelin Damage During Secondary Degeneration After Neurotrauma

Funding Amount
$895,244.00
Summary
Following injury to the central nervous system the damage spreads into nearby areas, leading to worse outcomes for the patient. We will generate nanoparticle systems to deliver effective therapies directly to the most vulnerable cells, critical for function. We will modify the nanoparticles so that they can get to the injury site, both early after injury, and after longer periods of time have elapsed. We will then test the nanoparticle systems to see if they are effective at preserving function
The Effects Of Human Epilepsy Mutations On Synaptic GABA-A Receptors Studied By Localization-based Superresolution Microscopy
Funder
National Health and Medical Research Council
Funding Amount
$524,215.00
Summary
The genetic epilepsies are debilitating neurological disorders that are frequently associated with mutations in genes encoding neurotransmitter-gated receptors in the brain. The goal of this project is to understand mechanisms that cause changes in neuronal communication and lead to epilepsy on a single receptor level. This will lead to an improved understanding of the mechanisms of epileptogenesis and new insights into ways of treating different epilepsies.
Neourobiology Of Human Epilepsy: Genes, Cellular Mechanisms,network And Whole Brain
Funder
National Health and Medical Research Council
Funding Amount
$17,652,824.00
Summary
The team is comprised of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. They will continue to identify genes underlying epilepsy and study how genetic variations result in development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.
How Does Chronic Epilepsy Result In Cardiac Electrophysiological Dysfunction?
Funder
National Health and Medical Research Council
Funding Amount
$737,112.00
Summary
Cardiac dysfunction is common in epilepsy, and could be an important contributor to the increased risk of sudden death in people with epilepsy (SUDEP). In this grant we will investigate: when changes in the cardiac function develop in relation to the epilepsy; if people with chronic epilepsy have similar changes; and what effect seizures and epilepsy has on the nerves innervating the heart. The outcomes have the potential to motivate new treatments and prevention for this important problem.
Decoding Dysfunctional Spinal Cord Circuitry In Chronic Pain.
Funder
National Health and Medical Research Council
Funding Amount
$516,101.00
Summary
Chronic pain is common, with one in five Australians having long-term pain that is serious enough to cause disability. Unfortunately this type of pain is difficult to treat, and current medicines are ineffective in many people, with unwanted side-effects. The aim of this project is to understand how signalling in the spinal cord changes following the development of chronic pain so we can find better strategies to reverse the symptoms and treat pain more effectively.
