Summary
The world is confronting a major new epidemic of premature heart disease that is being driven by a global increase in obesity. There are several factors that contribute to the increased risk of heart disease in overweight and obese people. One is a low blood level of the “good” HDL cholesterol that normally protects against heart disease. Another relates to a decreased ability to remove cholesterol from the walls of arteries where it builds up to cause heart disease.

There are several factors that contribute to the increased risk of heart disease in overweight and obese people. One is a low blood level of the “good” HDL cholesterol that normally protects against heart disease. Another relates to a decreased ability to remove cholesterol from the walls of arteries where it builds up to cause heart disease. A third is the fact that obesity is associated with a state of chronic inflammation of the blood vessels. This inflammation not only accelerates the development of heart disease but also makes people who have cholesterol accumulated in their arteries more likely to actually have a heart attack. And a fourth is the fact that the lining of blood vessels does not function normally in overweight and obese people. This loss of normal function is a very early sign of future heart disease. These factors are closely inter-related, with the “good” HDL playing a central role in removing cholesterol from arteries, inhibiting arterial inflammation and promoting normal function and repair of the lining of blood vessels. HDL is complex, consisting of a mixture of several subpopulations of particles that vary in shape, size and composition. Furthermore, these HDL subpopulations are continually remodelled as they circulate in blood in reactions promoted by a number of blood factors that change their size and composition. A major component of the research to be conducted in this program relates to understanding how the HDL subpopulations in human blood are regulated and how they protect against heart disease. The applicants have already made major contributions to understanding the functions of the “good” HDLs, how they take cholesterol out of cells in the artery wall, how they inhibit inflammation of the arteries and how they improve the function of the artery lining. We propose to extend these studies to establish how these protective functions can be enhanced, to find out which of the HDL subpopulations are most protective, and to identify how to increase the most protective HDLs in people at risk of heart disease.Read moreRead less

Summary
The team comprises internationally recognised experts in basic, clinical and public health applied research in cardiovascular disease, particularly atherosclerosis that is the commonest cause of death in Australia and other developed countries. Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol.

Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol. The significance of the proposed studies is that, on the one hand, they will provide new information on how 'good' lipoproteins protect us from atherosclerosis. This information can then be used to regulate 'good' cholesterol in a meaningful manner. On the other hand, the proposed studies will provide fundamental insights into how a range of lifestyle factors, physiological processes and pathological conditions relate to both the function of blood vessel-lining cells and susceptibility of individuals to atherosclerosis.Read moreRead less
This established team of investigators will research into the molecular control of white blood cell formation and function, using a multidisciplinary, team approach to fundamental biological questions with a focus on potential clinical and commercial outcomes. The team will also attempt to identify new validated targets for therapeutic intervention by using both forward and reverse genetic approaches in mice coupled with complete phenotypic analyses of the blood cell system.

The team have an internationally established reputation in bringing basic science discoveries to the point where they can impact directly on clinical diagnosis and therapy. The proposed research includes new treatment therapies for diabetic retinopathy, age related macular degeneration, and retinal vascular diseases. A new diagnostic technique for glaucoma and new instrumentation for detecting areas of poor blood flow and oxygen supply in the eye are also to be developed. Past successes in our current program grant make us confident that we can produce clinically useful outcomes from this new proposal.Read moreRead less
