Summary
Understanding the neural mechanisms that generate pathological pain remains one of the essential goals for the development of effective treatments for pain, chronic pain with less side effects. Lipids are able to modulate pain perception. We will determine the role of a molecule named sphingosine 1-phosphate as a basis for the development of therapies for the treatment of neuropathic pain.
Defining Vascular Health And Modifiable Risk Factors Over Time In Childhood.

Summary
Adult heart disease and strokes have their origin in childhood. We will follow healthy children and children with diabetes or obesity over 2 years during puberty when blood vessel disease is detectable. We will define which are the most sensitive markers of blood vessel disease and the continuum of risk factors. This is essential knowledge to best define children at risk and to test clinical and public health interventions.
Apoptotic Pathways In Pancreatic Beta Cells Leading To Type 1 Diabetes And Transplant Rejection

Summary
The destruction of insulin-producing beta cells in the pancreas by immune cells leads to the need for daily insulin injections in patients with type 1 diabetes. This project aims to understand how beta cells are destroyed. A knowledge of the process by which this occurs will indicate ways we can protect these cells. Our previous work has suggested strategies that may protect beta cells, and we aim to test these. Such protection may eventually allow beta cell replacement by transplantation.
Evaluation Of Multidisciplinary Care Plans For Patients With Diabetes

Summary
Care planning for patients with chronic illnesses and complex needs is a major part of the Commonwealth Enhanced Primary Care package. This initiative, announced in late 1999, provides access to Medicare Benefits Schedule (MBS) items to remunerate general practitioners, involved in developing multidisciplinary care plans in cooperation with other health care providers. An issue of importance, and the one that this project investigates, is whether disease specific care is addressed in care plans ....Care planning for patients with chronic illnesses and complex needs is a major part of the Commonwealth Enhanced Primary Care package. This initiative, announced in late 1999, provides access to Medicare Benefits Schedule (MBS) items to remunerate general practitioners, involved in developing multidisciplinary care plans in cooperation with other health care providers. An issue of importance, and the one that this project investigates, is whether disease specific care is addressed in care plans and whether the care planning process is associated with improved provision and outcomes of care for a specific chronic illness. The chronic illness that has been chosen for this research project is diabetes because of its prevalence in the community, importance in general practice and because there are accepted standards of process and outcomes of care against which diabetes care contained in EPC care plans can be bench marked. Diabetes is estimated to affect 7.5% of the adult Australian population with more than 85% of those affected having type 2 or mature onset diabetes. Increasingly care of type 2 diabetes is provided in primary care under share care arrangements with specialist diabetes services and in a multidisciplinary team approach involving the patient and their carer as well as relevant health professionals. A recent review has shown that there is a lack of evidence on whether multidisciplinary care is associated with improved process and outcomes of diabetes care. The project will involve 50 general practitioners and 200 of their patients with diabetes in South West Sydney. The design of the project involves audit of the care plans to examine the extent and quality of the diabetes care contained in comparison to accepted benchmarks. The project will also audit the patients' medical records for the year of care before and after the care plan. This care will be compared to published guidelines for process of care and goals for outcomes.Read moreRead less
Viral Triggers Of Autoimmunity And Type 1 Diabetes: A Prospective Study Of At Risk Children

Funding Amount

Summary
We are studying the role of viruses in causing type 1 (insulin dependent) diabetes. By following babies from birth, we can see whether early signs of damage to the body's insulin producing cells results from infection with particular viruses. We will study the genes and other features of these viruses to help us understand why they cause diabetes, and how they relate to other factors such as diet and vitamin D. The results may provide valuable information for the future prevention of diabetes.
Worldwide there are approximately 40 million people living with HIV-AIDS. An effective HIV vaccine does not exist at present. Therefore, current strategies to control the HIV pandemic include the use of life saving antiretroviral drugs. While the current drugs are successful in controlling infections, new and more effective agents are needed that inhibit HIV replication by distinct mechanisms due to the inevitable development of drug resistant strains of HIV.

Therefore, current strategies to control the HIV pandemic include the use of life saving antiretroviral drugs. While the current drugs are successful in controlling infections, new and more effective agents are needed that inhibit HIV replication by distinct mechanisms due to the inevitable development of drug resistant strains of HIV. The HIV reverse transcriptase enzyme is essential for HIV replication and has been a successful target for nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs). NNRTIs act in part by stabilizing the reverse transcriptase enzyme, thus blocking enzyme function. However, no drugs have been developed that can specifically prevent formation of the reverse transcriptase enzyme, which would result in the production of noninfectious viral particles. We propose that formation of the active reverse transcriptase enzyme, from a large polyprotein called Gag-Pol, proceeds through a homodimer intermediate, which represents an ideal target for blocking reverse transcriptase formation in HIV infected cells. This homodimer intermediate is an attractive target with greater potential for disruption with small molecule inhibitors compared to the mature reverse transcriptase enzyme as it is less stable than the reverse transcriptase found in viruses. This study will determine whether formation of the active RT enzyme is dependent on this intermediate. In addition, we will examine how the reverse transcriptase encoded on Gag-Pol regulates activation of the HIV protease, which is also critical for the formation of infectious virus particles. These studies will increase our understanding of how the virus produces infectious particles and will identify new approaches for targeting the HIV reverse transcriptase enzyme.Read moreRead less

Summary
This project concerns the basic biology of large white blood cells called macrophages. Macrophages are required for the immediate defence against infection, wound repair and normal turnover of tissues, but they can also produce toxic products that cause illness, especially in inflammatory diseases and cancer. We are studying a gene that is normally only produced in macrophages, but appears abnormally in many cancer cells.
