Summary
This project will develop a best practice approach to the diagnosis of influenza A H5N1 (Bird Flu) in Australian public health laboratories. Tests such as reverse transcription polymerase chain reaction (RT-PCR) are in use globally for influenza A H5N1 detection.

Tests such as reverse transcription polymerase chain reaction (RT-PCR) are in use globally for influenza A H5N1 detection. Some proprietary rapid influenza A tests also claim to detect influenza A H5N1. However there is little information on systematic evaluation of these, largely because there have been relatively few human influenza A H5N1 cases and patient specimens. Australian laboratories need authoritative guidelines as to optimal influenza tests, target genes and reagents. Development of a simple, potentially automated type specific test for influenza A H5N1 antibody such as enzyme immunoassay (EIA) is also desirable, as widely used tests cannot distinguish between infection with H5 or other influenza types. Reference methods such as haemagglutination inhibition (HAI) are cumbersome. In this project mock specimens for virus and antibody detection will be created using viral cell culture and infected chicken derived influenza A H5N1. This will be undertaken in physical containment level 4 (PC4) facilities in Australia's designated human and animal PC4 laboratories. This material will be used for (i) specimen panels to compare the performance of candidate laboratory tests (ii) positive control material in all tests undertaken and (iii) quality assurance exercises to ensure high standards of testing. Using these panels the group will assess influenza H5N1 RT-PCR, tests for detection of influenza proteins including immunofluorescence, and rapid point of care influenza A detection tests available in Australia. An EIA method currently used to detect influenza antibodies from different animal species will be refined to develop a simple test for type specific detection influenza A H5N1 antibodies, and subsequently evaluated using animal sera. A standard method for HAI reference serology for use in public health laboratories will also be recommended, and the best approaches to high throughput automated RT-PCR, and performing RT-PCR in the field on portable instrumentation will be explored. Recommendations for standard protocols for influenza A H5N1 will be developed and will submitted for review and endorsement by Commonwealth ministerial advisory committees.Read moreRead less
Host Metabolism And Responses Contributing To Flavivirus Replication And Pathogenesis

Funding Amount
$592,772.00
Summary
We aim to determine how viruses affect the cells they infect, In particular how they can alter the metabolism and balance of lipids in cells and how this impacts the bodies capability to respond immunologically. We believe that by understanding these basic principles we can target ares fr antiviral therapeutic potential.
Norovirus Infection At The Stress Granule-PKR-p-elF2α Axis

Funding Amount
$505,967.00
Summary
This project application will aim to investigate and understand how viruses that cause vomiting and diarrhoea are able to infect, proliferate and spread within the human body. It aims to address how viruses are able to avoid and replicate in the presence of an effective immune response. We have evidence showing that Noroviruses are able to exploit certain antiviral proteins to paradoxically aid in virus replication and survival.
Viral And Host Factors Determining Outcome Of Zika Virus Infection

National Health and Medical Research Council
Funding Amount
$910,780.00
Summary
The proposal aims at identifying viral and host factors determining outcomes of infection with Zika virus, a significant mosquito-transmitted pathogen associated with debilitating neurological pathology in new-borne babies from mothers infected during pregnancy. We will use cutting edge methodologies and infections models to bring our understanding of Zika virus infection to unprecedented level. The results could also facilitate identification of targets for effective anti-viral therapy.
A Humanised Mouse Model For Herpes Simplex Virus Pathogenesis

Funding Amount
$277,109.00
Summary
Herpes simplex virus (HSV) causes cold sores and genital herpes, diseases that persist and recur. This persistence is because HSV has several ways of stopping the body from detecting and eliminating the cells that it infects. This project will generate new tools that will help us to understand one of the ways that HSV hides from our defences and may be useful in developing immune-based therapies to treat the infection.
Prophylactic Vaccine Development For The Elimination Of Hepatitis C

Summary
A vaccine that prevents Hepatitis C is urgently needed to prevent infection and assist with global HCV elimination targets. This project grant will advance world-leading HCV vaccine candidates that generate both humoral and cellular immunity for clinical development.

Summary
Most individuals who are infected with hepatitis C virus (HCV) develop a persistent infection that is lifelong and are at risk of developing serious liver disease, including liver cancer. The evidence suggests that an inadequate immune response is responsible for the inability of the patient to resolve the infection, but it is not clear which stage of the immunological cascade might be targeted. In this project, we will test the hypothesis that HCV antigen induce supressor T cells This will have ....Most individuals who are infected with hepatitis C virus (HCV) develop a persistent infection that is lifelong and are at risk of developing serious liver disease, including liver cancer. The evidence suggests that an inadequate immune response is responsible for the inability of the patient to resolve the infection, but it is not clear which stage of the immunological cascade might be targeted. In this project, we will test the hypothesis that HCV antigen induce supressor T cells This will have the effect of inhibiting the immune response and result in the outcome that we currently recognise as persistent HCV infection.Read moreRead less
Current anti-HIV therapies can't cure HIV because HIV remains silent(latent) in long-lived cells. The HIV life cycle and virus production is linked to activation of the host cell, which is regulated by dendritic cells. This grant will explore how the factors controlling T cell activation and proliferation control virus expression and latency. By understanding how latent infection is established and maintained, these studies will potentially identify new ways to eliminate HIV infection.
