Dynamic Trafficking Of Amino Acid Transporters At Synapses And Their Role In Regulating Neurotransmission

Summary
Brain cells release chemical neurotransmitters to activate their neighbours. The most abundant neurotransmitter is glutamate, which mediates most of the communication in the brain. Following release, this neurotransmitter must be rapidly recycled to prevent levels being depleted and neurotransmission failing. The subject of this grant is to understand what molecules and pathways are used to recycle glutamate in the brain, and how its supply is controlled to sustain continual brain activation.
Astroglial Remodelling Of The Interhemispheric Midline Is Regulated By Deleted In Colorectal Cancer (DCC) Signalling And Is Required For Corpus Callosum Formation

Funding Amount

Summary
The integration of information between the brain hemispheres occurs via a large bundle of connecting nerve fibres called the corpus callosum. People with a genetic mutation in DCC display mirror movement disorder and some have a severe brain defect where the corpus callosum fails to form, but at present we don’t understand the function of this gene. In this study we will investigate how DCC functions in early brain development to regulate corpus callosum formation and mirror movement disorder.
A New Target For Antidepressant Treatment: Microglia Mediated Neuroinflammation

Summary
Depression is the leading cause of non-fatal disease burden in Australia. Unfortunately, current antidepressants do not provide adequate levels of relief and it is accepted that we need to develop more effective treatments. We have recently shown that a drug that reduces inflammation in the brain also reduces depression-like symptoms. This project aims to extend upon these extremely promising findings, in the hope of developing a new and more effective generation of antidepressants.
Differentiation And Fate In The Developing Sympathetic Ganglia

Funding Amount

Summary
This project seeks to understand how a small number of founder cells can divide and differentiate into the myriad different types of cells that make up the mature nervous system. It uses modern genetic techniques to follow progenitor cells as they mature into mature neurons.
The Role Of Gliosis In Advanced Retinal Degeneration

Funding Amount
$457,785.00
Summary
The development of treatments that restore vision assumes that the output neurons of the retina remain intact. Yet, there is now considerable evidence that the neurons that signal from the retina to the brain are altered in those that have degenerative diseases of the retina. Here, we will examine the cause of these cellular changes in an animal model and seek to prevent the loss of output neurons. This information is crucial for the development of treatments that seeks to restore vision.
ONTRANS: Oral Nicotinamide For Skin Cancer Chemoprevention After Transplant

Summary
The skin’s immune system is a key defence against skin cancer. Transplant recipients, who are chronically and profoundly immune suppressed to prevent rejection, have a 50-80 fold increase in skin cancer risk. Nicotinamide (vitamin B3) reduced skin cancer in our recent Phase 3 trial in immune competent individuals. A pilot study in renal transplant patients showed similar results. This project will determine at the Phase 3 level whether nicotinamide reduces skin cancers after kidney transplant.
The Contribution Of Aberrant Wnt Signalling To Neuronal And Vascular Pathology In Retinal Disease

Funding Amount
$561,342.00
Summary
Neuronal damage and vascular abnormalities are features shared by many retinal diseases. We will use a novel transgenic model to study the contributions of aberrant Wnt signalling in retinal neuronal and vascular pathology, and also, to test strategies for neuroprotection and inhibition of vascular abnormalities. Success in the project may identify novel therapeutic targets leading to safer and more effective treatments for retinal diseases.
Human Cytomegalovirus Encoded Control Of The Latent Phase Of Infection
Funder

Funding Amount
$639,871.00
Summary
Human cytomegalovirus has the ability to hide in the body of a person throughout their life time without it making them ill but the virus can awaken (reactivate) from this latent state and produce new virus. In immunosuppressed people such as transplant patients this reactivation causes significant problems, even death, yet this latency remains poorly understood. This project will help us to understand how the virus can hide successfully from the immune system in a latent form in the human host.
TOLERANCE OR REJECTION – THE ROLE OF INNATE IMMUNITY IN DETERMINNG THE FATE OF A KIDNEY ALLOGRAFT

Funding Amount
$506,413.00
Summary
Transplantation is the optimal management for people with organ failure. Tolerance, to retain transplant function without immunosuppression, remains the key goal but is seldom achieved. We propose to block Toll-like receptor signalling to achieve kidney transplant tolerance in mice. If successful, we would translate this into clinical trials in human, seeking to achieve organ transplantation without the risks of cancer, infection and premature death that are currently faced by organ recipients.
Combining Immune Monitoring And Immunotherapy To Tackle Cytomegalovirus Infections In Solid Organ Transplant Patients

Summary
Clinical management of infectious complications in kidney and heart/lung transplant patients remains significant challenge. Although prophylactic/pre-emptive treatment with antiviral drugs have shown dramatic improvements in the control of these infections, long-term treatment with these drugs is associated with significant toxicity, the appearance of drug-resistant virus isolates and significant health cost.

Although prophylactic/pre-emptive treatment with antiviral drugs have shown dramatic improvements in the control of these infections, long-term treatment with these drugs is associated with significant toxicity, the appearance of drug-resistant virus isolates and significant health cost. In this proposal we will develop novel strategies to identify high risk patients and treat these patients with killer T cells.Read moreRead less
