Funding Amount
$521,429.00
Summary
The project will investigate interaction between the AIDS virus, HIV-1, and the human cell it grows in specifically focusing on a human protein called eEF1A. Our research shows eEF1A is required for HIV-1 growth by regulating a step in the virus life cycle called reverse transcription. The goal of this project is investigate how interaction with eEF1A helps HIV-1 reverse transcription and to find drugs that block HIV-1 interaction with eEF1A.
Dengue virus is the most important mosquito-borne viral disease, with 2/3 of the world's population at risk. There is currently no treatment available for dengue. Our proposal aims to progress a safe and effective new treatment (4-HPR) against Dengue towards the clinic, generating all the required pharmacokinetic and pre-clinical animal data necessary to progress to a future clinical trial in humans. We will also investigate the use of 4-HPR as a dengue preventative.
Host Cell Signalling During HTLV-1 Infection: Novel Insights And Interventions

Summary
Human T-leukemia virus 1 (HTLV-1) establishes a life-long infection and causes cancer and immune dysfunction. This study aims to find a cure for HTLV-1 by inducing the specific death of infected cells using novel therapeutic drugs that target host cell death pathways. Dead infected cells are then naturally cleared from the system along with the viral infection. The impact of HTLV-1 infection on tuberculosis severity will also be examined.
Targeting Novel Sites On Reverse Transcriptase For HIV Treatment And Prevention

Summary
HIV/AIDS remains a major global threat with 37 million individuals living with HIV in 2014. Antiretroviral drugs have transformed HIV from a death sentence into a chronic disease. Public health organisations recommend dramatic scale up of drugs for HIV treatment and prevention. However, a major threat is that drug options will be exhausted due to drug resistance and toxicity. The major aim of this study is to undertake fundamental studies to advance the development of a new HIV drug class.
Hepatitis C virus is a major medical problem in Australia and many other parts of the world. The viruses causes a persistent infection in most infected individuals that results in serious liver disease and liver cancer in a proportion of patients. Treatment is only possible for a small percentage of patients and many patients are infected with viruses which are resistant to the best contemporary treatment regimens. The aim of this project is to develop systems which will result in the assembly o ....Hepatitis C virus is a major medical problem in Australia and many other parts of the world. The viruses causes a persistent infection in most infected individuals that results in serious liver disease and liver cancer in a proportion of patients. Treatment is only possible for a small percentage of patients and many patients are infected with viruses which are resistant to the best contemporary treatment regimens. The aim of this project is to develop systems which will result in the assembly of virus particles which can be used to examine the efficacy of potential antiviral agents, either in the test tube or by infecting an animal model. In particular, we will examine the contribution of a small viral protein, p7, on virus assembly and secretion from the infected cell. Recent data suggests that p7 can function to help release virus from the infected cell and a number of inhibitors of p7 function have been described. We will then use the systems which we develop to determine if these inhibitors can inhibit virus replication in the test tube and in animal models.Read moreRead less
Towards A New Class Of Reverse Transcriptase Inhibitor For HIV Prevention

$688,833.00
Summary
There remains an urgent need for new HIV prevention strategies. New HIV drugs that block the virus by distinct ways are needed to prevent transmission of drug resistant HIV. This study seeks to identify very small molecules called “fragments” that bind to previously undiscovered pockets on the HIV reverse transcriptase to stop its function, and that can be used as building blocks to design more potent HIV drugs to be used solely for HIV prevention.

Public health organisations recommend dramatic scale up of drugs for HIV treatment and prevention. However, a major threat is that drug options will be exhausted in the long-term due to drug resistance and toxicity. The major aim of this study is to advance the development of an entirely new drug class for HIV.

Congenital CMV is the second most common cause of fetal malformation in Australia, and yet most pregnant mothers do not know about it, nor how to prevent congenital CMV in their baby. It is a viral infection that can severely damage the unborn baby. Our research aims to find more about how the virus damages the baby, and whether antiviral drugs are useful in reducing infection of the baby, and also reducing damage to the baby from such infection.

Summary
Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease. This proposal plans to examine how two proteins from the HCV, core and NS5A, interact with host proteins and pathways to facilitate viral replication and release of HCV; two processes that are poorly understood. Specifically we will tag viral proteins to allow us to investigate the HCV life cycle in living cells and determine the role of core and NS5A in facilitating HCV replication.

Summary
Dendrimers are nanoparticles with highly branched structures and they are being developed as topical microbicides to prevent the sexual transmission of HIV. This study will determine how dendrimers block HIV entry into host cells so that we can design more effective inhibitors and microbicides.
