Summary
Diseases such as autoimmune gastritis, multiple sclerosis and diabetes arise because a rogue immune system has turned inwards to attack our organs. The organ destruction follows from recognition by the immune system of specific molecules in these organs. These autoimmune diseases are incurable and controlled mainly by long-term administration of substances that suppress the immune system, often with serious side-effects. A rational approach is to render the rogue immune system harmless by removi ....Diseases such as autoimmune gastritis, multiple sclerosis and diabetes arise because a rogue immune system has turned inwards to attack our organs. The organ destruction follows from recognition by the immune system of specific molecules in these organs. These autoimmune diseases are incurable and controlled mainly by long-term administration of substances that suppress the immune system, often with serious side-effects. A rational approach is to render the rogue immune system harmless by removing the cells that recognize these particular molecules. This can be achieved by a Trojan horse approach in which the molecules are delivered to the immune system such that that the immune cells that recognize them are removed. To deliver these molecules to the immune system we will genetically engineer bone marrow stem cells, or embryonic stem cells that generate these stem cells, because they are precursors of mature immune cells. Rejection of organ transplants arise in a similar way and also require long-term immunosuppression. A similar approach can therefore be taken to promote acceptance of foreign organ grafts. In the aged, we will combine these approaches with rejuvenation of the immune system by blockade of sex steroid production and-or by creation of a new immune organ.Read moreRead less

Summary
The broad aims of the Program are to develop novel strategies in the prevention and treatment of chronic heart failure. This will involve investigating new targets for pharmacological therapies, evaluating whether common co-morbid disease states such as diabetes alter the efficacy of these therapies and investigating the role of stem-cell therapy in this setting. The Program will also evaluate the contribution of non-heart failure drugs to the burden of heart failure, determine the impact of rur ....The broad aims of the Program are to develop novel strategies in the prevention and treatment of chronic heart failure. This will involve investigating new targets for pharmacological therapies, evaluating whether common co-morbid disease states such as diabetes alter the efficacy of these therapies and investigating the role of stem-cell therapy in this setting. The Program will also evaluate the contribution of non-heart failure drugs to the burden of heart failure, determine the impact of rurality on prescribing for this condition and explore systems of optimising delivery of best practice to the community. This research formalises the existing collaborative efforts of a team of investigators that span all aspects of research into the therapeutics of CHF from basic laboratory research to evaluation of patients in clinical trials and public health translational aspects of this condition. The Chief Investigators and Principal Investigators have an existing successful research collaboration which will be greatly expanded via Program.Read moreRead less

These include cancers of the cervix and blood system, and autoimmune diseases such as rheumatoid arthritis and type 1 diabetes. Working together, the team have made discoveries that have led to testing and clinical development of new treatments for these diseases. In this programme, the team aims to discover mechanisms regulating the immune response, and to exploit this knowledge to define new ways of switching on or off, specific immune responses. We will particularly seek to develop novel vaccines for chronic infections and autoimmune diseases, and to improve the safety of bone marrow transplantation.Read moreRead less

The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammator ....The foot soldiers of the immune system, the white blood cells, constantly march through the body seeking out invaders, but kept in check by the barrier of endothelial cells that lines the inside of blood vessels. When infection occurs, molecular messages are transmitted amongst the white cells and between white cells and edothelium, to activate the immune cells to pass out of the blood vessels and mount a defence. Unfortunatley, the activation system sometimes goes awry, resulting in inflammatory or allergic disease, such as arthritis or asthma. This team of researchers from the Hanson Institute in Adelaide, combining expertise in molecular and cell biology, protein chemestry, structual biology and animal models, has been working together for over 10 years, investigating the molecular mechanisms involved in controlling the formation and activities of blood vessels and white blood cells. This program seeks to further that understanding, and to develop drugs that have the potential of ameliorating the inflammatory condition.Read moreRead less
Regulation Of Bone Resorption And Formation In Health And Disease

Summary
Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. ....Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. Osteoporosis results from an excess of bone breakdown over formation, and our Program aims to identify the factors that regulate these processes, and develop new therapies that can modify them. We will also determine what it is about bone cell properties that make some cancers, especially those of breast and prostate, particularly prone to spread to bone.Read moreRead less
