Summary
Recent research suggests that Multiple Sclerosis could first be triggered by the death of a type of brain cell called an oligodendrocyte. These cells insulate nerve cells in the brain which help them function normally. We will test the idea that death of oligodendrocytes impairs nerve cell function by causing inflammation and by depriving nerve cells of energy. We will determine whether preventing inflammation and feeding the nerve cells an alternative source of energy can restore normal functio ....Recent research suggests that Multiple Sclerosis could first be triggered by the death of a type of brain cell called an oligodendrocyte.

Ultradian rhythms in basal metabolism; relationship to thermoregulation, cardiovascular function and behavioural arousal. Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function. Our findings may provide a new foundation for discovering strategies that alter basal metabolic rate in a manner that improves health and reduces the incidence of obesity related ....Ultradian rhythms in basal metabolism; relationship to thermoregulation, cardiovascular function and behavioural arousal. Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function. Our findings may provide a new foundation for discovering strategies that alter basal metabolic rate in a manner that improves health and reduces the incidence of obesity related disease such as heart attack and stroke. Thus this research proposal is of special relevance to National Research Priority 2: Promoting and Maintaining Good Health. Obesity and obesity-related medical conditions particularly affect older people, so that our research is also highly relevant to National Research Priority 2 sub-areas: Ageing well, Ageing productively.Read moreRead less

Summary
Promotion of NAD+ anabolism to promote lifespan. The project aims to identify mechanisms of ageing, the role of stress on the ageing brain and how NAD+ modulates these effects. NAD+ maintains cellular energy, repairs DNA and performs other essential cell functions. Intracellular NAD+ levels, the essential substrate for sirtuin activity including SIRT2, decline with age in humans and physiologically aged rats. This project will investigate the mechanisms by which pharmacological strategies design ....Promotion of NAD+ anabolism to promote lifespan. The project aims to identify mechanisms of ageing, the role of stress on the ageing brain and how NAD+ modulates these effects. NAD+ maintains cellular energy, repairs DNA and performs other essential cell functions. Intracellular NAD+ levels, the essential substrate for sirtuin activity including SIRT2, decline with age in humans and physiologically aged rats. This project will investigate the mechanisms by which pharmacological strategies designed to elevate intracellular NAD+ levels will maintain optimal SIRT2 function to extend lifespan and improve age-related cognitive decline in vivo. Potential outcomes include using NAD+ to improve brain health in advanced old age.Read moreRead less
What is normal brain ageing? An investigation of changes in brain structure and cognition in mid-life. Pathological brain changes associated with cognitive decline later in life become detectable in the 40s and sometimes earlier, yet little is known about what constitute normal brain ageing in midlife. Using a number of neuroimaging techniques, this project will develop a detailed map of brain and cognitive ageing in middle-age and their predictors.
Understanding brain mechanisms that control autonomic function. This project aims to understand the how the brain regulates sympathetic nerve activity, thereby increasing our understanding of the biology and function of nascent neurons on the adult brain stem. This challenges the current notion that new neurons are only made during development. The project will also determine how brain inflammation impacts blood-brain barrier function and affects sympathetic nerve regulation. The basic fundament ....Understanding brain mechanisms that control autonomic function. This project aims to understand the how the brain regulates sympathetic nerve activity, thereby increasing our understanding of the biology and function of nascent neurons on the adult brain stem. This challenges the current notion that new neurons are only made during development. The project will also determine how brain inflammation impacts blood-brain barrier function and affects sympathetic nerve regulation. The basic fundamental insights and conceptual advances into how autonomic function is controlled by the brain will provide a better understanding of these fundamental processes and will contribute to Australia’s priority research areas to improve health and advance product development.Read moreRead less

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.
From rehabilitation to recovery after stroke : a model to optimise consumer and carer involvement. The National Research Priorities include 'ageing well, ageing productively'. Within this priority, it is necessary to be inclusive of those who have ongoing disabilities and/or chronic disease.

The National Research Priorities include 'ageing well, ageing productively'. Within this priority, it is necessary to be inclusive of those who have ongoing disabilities and/or chronic disease. This project aims to facilitate healthy lifestyles and community involvement in a group who have significant barriers to achieving their potential. The high incidence of depression and poor quality of life in stroke survivors and their carers emphasises the need to enhance wellness in these people. The study will develop a model for promoting recovery and community reintegration in stroke survivors, with the goal of enabling stroke survivors and their carers to actively participate in the community and pursue personal goals.Read moreRead less
Toll Like Receptor signalling as a mediator of sex differences in pain, opioid and alcohol action. Brain immunology will be examined in this project to see if the signalling of a receptor called Toll Like Receptor 4 can explain sex differences in pain, and the action of pain killers and alcohol. These findings will have significant implications on the understanding of male and female brains, and will assist in the design of new drugs to treat brain and spinal cord diseases.

This project aims to identify and characterise novel resident immune cell subsets within the brain and retina, and their close supporting tissues. The project expects to generate new knowledge in the areas of neuroimmunology and ocular immunology by using molecular and cellular techniques to examine the diversity of immune cells within the brain and retina. It is expected that the project will advance our understanding of the biological mechanisms that protect the central nervous system from harmful inflammation and thus improve our knowledge of the immunobiology of the brain and eye.Read moreRead less
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.
