Brain sodium channel: functional role of developmentally regulated alternative splicing. This project will identify the roles of neonatal and adult forms of a sodium channel in the function of neurons in the developing brain. Sodium channels are vital for brain function and this study will improve our understanding of the function of healthy brain as well as of underlying mechanisms of some neurological disorders.
Elucidating the neural pathways and genetic basis of speech. The project will elucidate the biological basis of speech, a unique feature of the human condition. The project will do this by i) discovering genes associated with speech disorder and ii) defining the neural pathways associated with speech production. This study will address critical questions regarding gene, brain and behaviour relationships in speech.
Unraveling the role of N-acetyl-aspartate in normal brain function and disease. The purpose of this project is to define the role of the predominating brain chemical N-acetyl-aspartate for normal nerve cell function and as toxic agent causing neurological illness and severe mental health problems. Findings of this research will enhance the design of novel therapies involving pharmacological and genetic treatment.
Defining the cellular impacts of protein aggregation in neurodegenerative disease with an aggreomics platform. The brain disease Huntington’s is caused by abnormally shaped proteins that assemble into toxic clusters. This project will design new bioprobes to track how these clusters form and cause damage to cells. This strategy will also provide new opportunities for discovering novel therapeutic targets.
Increasing the utility of tetanus toxins by protein engineering. There are a variety of common diseases that are the result of muscular defects. Some of these may be able to be treated with an agent that increases muscle tone, thereby giving benefit to the patient in the alleviation of symptoms. This project aims to use some of the most potent substances known, bacterial toxins, and engineer them to be valuable agents for treatment of certain muscular disorders.
Benefits of blood pressure lowering to combat cardiovascular disease. Stroke and heart attack are the commonest causes of death and adult disability. In Australia, approximately 50,000 people die from cardiovascular disease each year. This project will attempt to prevent stroke/heart attack and to improve quality of life by exploring better management of high blood pressure.
Novel computational tools for the analysis of sympathetic nervous system activity. This project will investigate electrical signals from the heart, resulting in novel tools for the assessment of sympathetic nervous system activity. The findings will contribute to advancing Australia's international leading position in health technology and improve community health.
Understanding the mechanisms of ion conduction and drug action in voltage gated sodium channels. Voltage-gated sodium channels initiate electrical impulses in nerve and muscle and are the target of many local anaesthetic, anti-epileptic and anti-arrythmic drugs. The publication of atomic resolution structures of homologous proteins from bacteria in the last 18 months has now made it possible to gain a detailed understanding of how these channels work, and how they are influenced by drugs. This p ....Understanding the mechanisms of ion conduction and drug action in voltage gated sodium channels. Voltage-gated sodium channels initiate electrical impulses in nerve and muscle and are the target of many local anaesthetic, anti-epileptic and anti-arrythmic drugs. The publication of atomic resolution structures of homologous proteins from bacteria in the last 18 months has now made it possible to gain a detailed understanding of how these channels work, and how they are influenced by drugs. This project aims to determine the basis of ion permeation and selectivity in the channels and explain the mechanisms of action for a number of common drugs. This will provide a foundation for future drug development to target specific channels for improved treatment of epilepsy, chronic pain and arrythmias. Read moreRead less
Mapping, recovery and remediation of arm coordination deficits after stroke. Coordination of arm movement is a significant problem after a stroke. This innovative project will underpin new treatments by focusing on what type of stroke causes difficulty in coordinating arm movement, describing the coordination difficulties in detail and investigating mechanisms of recovery and treatment.
Broad spectrum nanomedicine for Meningitis treatment. Brain inflammatory diseases are among the top ten infectious causes of death. The project aims to provide Australian doctors with a superior alternative of treating infections that do not respond to conventional antibiotics. The nanomedicine developed will reduce the burden of hospital and boost Australia economy in the biomedical sector.
