Dopamine Neuron Ontogeny: Convergent Neurobiological Pathway For Risk Factors Of Schizophrenia

Summary
Schizophrenia is associated with changes in dopamine (a signalling molecule in the brain). These changes are present prior to psychosis, suggesting they begin early in development. Our aims are to manipulate key factors in the development of brain dopamine systems to clarify their role in psychosis and schizophrenia. This work has the potential to identify early brain changes that lead to schizophrenia, which in turn may generate better diagnoses and outcomes for people with this disorder.
Substance abuse is a significant social and economic burden upon Australian societies and on societies around the world. Treatment remains problematic due to the multi-layer nature of the disease, difficulties with treatment compliance and less than ideal treatment regimes. The present study aims to improve treatments for alcohol and drug abuse using pre-clinical models to identify and characterize a new brain system implicated in drug-seeking.
High Penetrance Deleterious Mutations In Blinding Glaucoma

Summary
This project aims to identify the genes most commonly mutated in individuals with advanced glaucoma. Identification of such genes will lead to improved understanding of glaucoma pathogenesis, a better ability to predict risk, and the identification of drug targets for novel therapies.
Salt (sodium) is an essential electrolyte. Our convincing and complementary findings provide compelling evidence for a link between evolutionarily ancient “instincts” and substance abuse. This proposal is translational, including studies in opiate dependent humans. Our studies will establish how and where in the brain endogenous opioids are implicated in the gratification of salt appetite, how salt appetite is altered in opiate dependency and if salt appetite recovers following opiate withdrawal
Delineating The Relationship Between Iron And Peroxisomal Disorders: The Role Of The Peroxisomal Enzyme GNPAT In Iron-Overload Disorders

Summary
Hereditary haemochromatosis is one of the most common genetic disorders in humans, affecting 1 in 200 Australians. We have identified a change in a peroxisomal gene which may affect iron levels in humans. The prevalence of this gene change in Australian haemochromatosis patients will be examined followed by a systematic analysis of how this protein controls iron levels in the body. Our goal is to identify and diagnose genetic changes which influence iron loading in haemochromatosis patients.
The Interplay Between Viperin, Peroxisomes And The Cellular Innate Antiviral Response

Funding Amount
$556,127.00
Summary
Infection with a virus initiates a cellular antiviral response that attempts to limit viral replication, however how this response is regulated is not well understood. In this proposal we will investigate a cellular protein (viperin) that can regulate this process by interaction with peroxisomes to amplify the antiviral response. This work will provide possible targets for therapeutic manipulation of the innate immune response that will be applicable to a wide range of viral infections.
Frontotemporal Dementia And Motor Neurodegenerative Syndromes

Summary
Frontotemporal degeneration of the brain is a leading cause of morbidity. It is a pathologically heterogeneous group of rapidly-progressive disorders with behavioural, language and motor deficits. This research program brings together international leaders in clinical, pathological and biological research of these syndromes, aiming to fast track new knowledge and innovations to develop the necessary tools and therapies to effectively diagnose, manage and treat these disorders.
Effects Of Latrepirdine On Beta Amyloid Clearance, Aggregation And Neurodegeneration In Alzheimer�s Disease

Funding Amount
$512,647.00
Summary
Alzheimer's disease (AD) is becoming more common with our growing aged population and currently no treatment exists that halts disease progress. The increasing health costs of AD underscore the need for development of any treatment that will slow or halt AD pathogenesis. By understanding the mechanisms of action of a drug [latrepirdine] that has recently shown some promise in phase II clinical trials, related drugs that are more specific and potent will be developed.
A New Target For Allergic Inflammation: The Sphingolipid Pathway

Funding Amount
$588,617.00
Summary
Collectively, allergic diseases contribute immensely to the burden of health care in Australia. Notably, allergic reactions are symptomatic responses to a normally innocuous environmental antigen. Allergic diseases include asthma, hay fever, food allergy, anaphylaxis, insect sting and drug allergy. This project aims to understand the underlying mechanisms associated with allergic reactions such that it may aid in the identification of novel targets for the development of new treatments.
