Development And Validation Of A Latent Tuberculosis Diagnostic

Summary
Globally, tuberculosis is a leading cause of death with 9.6 million new diagnoses in 2014. The diagnosis of latent TB infection is important, but is difficult to make because current assays are suboptimal. We have developed a very simple assay which detects responses to TB antigens by co-expression of two surface markers expressed by CD4+ T cells. We propose to develop this into a highly standardised kit for the diagnosis of TB with our commercial partner Cytognos.
Regulation Of Secretion Of The Fungal Virulence Determinant, Phospholipase B

Summary
Serious systemic infections due to fungi have increased dramatically in the past few years, especially in people with poorly functioning immune systems. Treatment of these conditions is problematic because the few drugs which are available are not highly effective, and-or cause significant side-effects. Little is understood of how fungi cause disease, and this problem must be addressed if these infections are to be contained. We have discovered that the enzyme, phospholipase B (PLB), is secreted ....Serious systemic infections due to fungi have increased dramatically in the past few years, especially in people with poorly functioning immune systems. Treatment of these conditions is problematic because the few drugs which are available are not highly effective, and-or cause significant side-effects. Little is understood of how fungi cause disease, and this problem must be addressed if these infections are to be contained. We have discovered that the enzyme, phospholipase B (PLB), is secreted by the disease-causing fungus, Cryptococcus neoformans, and that it is important in enabling the fungus to invade the host's cells and spread around the body from the lungs to the brain, where it can cause meningoencephalitis. PLB is also produced by other disease-causing fungi. The mechanism of PLB secretion is completely unknown. In this project we aim to determine the pathways involved in PLB secretion with the intention of exploiting steps unique to pathogenic fungi, for the future design of new anti-fungal drugs.Read moreRead less
Learning Software Security Analysers with Imperfect Data. This project aims to systematically investigate next-generation learning-based software security analysis to detect vulnerabilities in real-world large-scale software. The expected learning-based foundation will support the handling of imperfect data in order to provide a precise, scalable and adaptive security analysis of the critical software components, thus capturing important security vulnerabilities missed by existing approaches.

This project aims to systematically investigate next-generation learning-based software security analysis to detect vulnerabilities in real-world large-scale software. The expected learning-based foundation will support the handling of imperfect data in order to provide a precise, scalable and adaptive security analysis of the critical software components, thus capturing important security vulnerabilities missed by existing approaches. The success of this project will further enhance the international competitiveness of Australian research in this important field and will benefit any Australian industry and business where software systems are deeply-rooted, such as transportation, smart homes, medical devices, defence and finance.Read moreRead less
Development Of A New High Throughput Screen For Drug Binding To HERG K+ Channels

Funding Amount
$351,320.00
Summary
Inadvertent drug block of hERG, a potassium channel in the heart, can cause cardiac arrhythmias and sudden cardiac death. Screening for hERG toxicity has become a major hurdle for development of new drugs. We will use a mutant hERG protein that has enhanced drug binding to develop a high throughput test for hERG toxicity. Identification of dangerous drugs early in the drug discovery process will save the pharmaceutical industry millions of dollars in the costs of brining new drugs to market.
Centre Of Research Excellence In Medicines Intelligence

Funding Amount

Summary
The NHMRC Centre of Research Excellence in Medicines Intelligence is a co-ordinated research program that will accelerate the development and translation of evidence on prescribed medicines use and outcomes for regulators and payers. The CRE is perfectly placed to embrace the national ‘call to action’ from the Health Minister's recent announcement to establish Quality Use of Medicine Safety as a National Health Priority.
Invasive fungal infections are a serious, escalating health issue. They cause severe disease with high death rates and are very costly to the health system. Current drugs often have suboptimal efficacy and cause side effects. New drugs are needed urgently. Many fungi, including the AIDS-related pathogen, Cryptococcus neoformans, secrete phospholipase B (Plbp) to facilitate infection. We will identify and investigate the Plbp secretion pathway as a novel anti-fungal drug target.
Glycine Transporters regulate the concentration of glycine in the spinal cord and brain. It has been suggested that elevating glycine levels in these regions may be useful in treating pain and schizophrenia. This project will provide the basis for the development of new glycine transport inhibitors that may be used to treat these conditions.
Glucocorticoid Resistance In Paediatric Acute Lymphoblastic Leukaemia

Funding Amount
$394,721.00
Summary
Glucocorticoids are among the most effective drugs used in the treatment of many haematological malignancies, including leukaemia, lymphoma and multiple myeloma. However, the development of tumour cell resistance to these drugs remains a significant problem, and clinically relevant mechanisms of glucocorticoid resistance remain poorly understood. This project aims to define mechanisms of resistance to glucocorticoids and develop new drugs to reverse resistance.
Translational Research Initiatives In Acute Leukaemia

Funding Amount
$631,010.00
Summary
Recent research has focussed on molecular characterisation of high-risk acute leukaemia subtypes. This proposal will combine the power of genomic analysis, global analysis of protein kinases and stringent preclinical drug testing in order to improve the treatment of these high-risk acute leukaemia subtypes. Several innovative and interrelated projects within this Program will utilise a unique and clinically relevant experimental model to achieve their goals.
Targeting Microtubules To Overcome Chemoresistance In Pancreatic Cancer
Funder
National Health and Medical Research Council
Funding Amount
$594,336.00
Summary
Pancreatic cancer is a devastating disease with a dismal prognosis because it is extremely resistant to chemotherapy agents. We plan to examine the expression of proteins called microtubules in pancreatic cancer and assess their role in drug resistance. It is anticipated that the findings of these studies will lead to the development of effective approaches to sensitise the cancer cells to chemotherapy agents.
