PROTEIN PROFILING FOR THE IDENTIFICATION AND MONITORING OF LYSOSOMAL STORAGE DISORDERS AND OTHER NEUROLOGICAL DISEASES

Summary
Lysosomal storage disorders (LSD) are a group of more than 45 progressive genetic diseases, that result from the absence or impaired function of a specific enzyme in each of the body's cells. Lysosomes rid the cell of excess waste. Impaired enzyme function halts this process and waste begins to accumulate (or 'store') in the cell. Disease severity and patient longevity is variable, but severely affected patients often die by their mid-teens. LSD can affect the skeleton and joints, respiratory an ....Lysosomal storage disorders (LSD) are a group of more than 45 progressive genetic diseases, that result from the absence or impaired function of a specific enzyme in each of the body's cells. Lysosomes rid the cell of excess waste. Impaired enzyme function halts this process and waste begins to accumulate (or 'store') in the cell. Disease severity and patient longevity is variable, but severely affected patients often die by their mid-teens. LSD can affect the skeleton and joints, respiratory and cardiovascular systems, the brain, the eyes, the ears and the airways. As affected children become older, symptoms worsen. Patients often require frequent hospitalisation, and medical and surgical intervention. Approximately 10 to 15% of the general population are affected or carriers of an LSD. In Australia, one LSD child is born in every 5,000 live births. Diagnosis often takes several years, and families often have other children before their affected child is diagnosed. LSD are, therefore, a considerable burden to not only the families but also to the health care system. The goal of the Lysosomal Diseases Research Unit is Diagnosis at birth and effective therapy for lysosomal storage disorders. To this end we have been working toward the development of a newborn screening program for LSD and improved methods for the diagnosis and monitoring of therapy in this group of diseases. In this project we propose to develop and evaluate the use of protein profiling (looking at many diagnostic markers at the same time) to achieve these goals. The technology developed in this project will have potential application beyond LSD. Lysosomal dysfunction has been implicated in Alzheimer's disease and Parkinson's disease; in addition lysosomal proteins are reported to be involved in the spread of some cancers and may be useful markers for early detection. We will collaborate with other research groups to further develop protein profiling in these areas.Read moreRead less

The Optimization Of Rapid Diagnostic Tests (RDTs) For Malaria
Funder

Funding Amount
$44,934.00
Summary
The ability to reliably diagnose malaria infections is key to both the management of individual patients as well as public health efforts to control the disease. Current Rapid Diagnostic Tests (RDTs) for malaria have unacceptable sensitivity. The project will determine the low sensitivity of current malaria RDTs available on the market and help produce a malaria RDT with higher sensitivity and stability. This will bring great health benefits to millions of people.
Development And Prototype Manufacture Of A High-throughput CD4 T-cell Test For Management Of HIV/AIDS Infections
Funder
National Health and Medical Research Council
Funding Amount
$163,150.00
Summary
CD4 T-cells are the target of HIV-AIDS infection, and monitoring of HIV-infected patients for these cells is an essential part of disease management. Current CD4 testing methods rely on expensive equipment and reagents and high levels of training, or else they have low throughput that limits their use. This project will develop a standard laboratory assay method for testing CD4 T-cells, increasing the access of patients to CD4 testing, and to HIV therapy, worldwide.
