Australian Research Council
Funding Amount
$350,000.00
Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.

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.
Herpesviruses infect us all and cause cancer, blindness, and congenital disability. Developing vaccines requires information from both patients and experimental animals. CD4 T cells seem to suppress directly virus replication, and cells in the nose provide an important way for herpesviruses to get in. We will test whether CD4 T cells can clear nasal infection; what targets they recognize; and how they act. Thus we can establish whether CD4 T cell-directed vaccines might protect against disease.
Host Metabolism And Responses Contributing To Flavivirus Replication And Pathogenesis

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.
I am an infectious diseases physician and virologist/immunologist focused on developing and testing vaccines against the AIDS virus. I intend to achieve this by advancing novel vaccine concepts that stimulate broad and potent immunity and evaluating these vaccines in rigorous laboratory models and then moving them towards clinical trials.
A vaccine for hepatitis C virus (HCV) is not yet available. Immune responses that are able to protect against infection are possible, making the production of a vaccine a realistic goal. We have produced a unique HCV vaccine and are now poised to test our vaccine in novel humanised animal models. Our research will allow us to determine the immune responses responsible for providing protection against HCV. Our data will be highly significant for future HCV vaccine studies in humans.
Understanding The Role Of NS Segments In Evading Influenza A Virus-specific Humoral And T Cell Immunity

Summary
Influenza viruses developed two ways to survive against host immune response: (i) mutating in its genes to escape host immune response, which may cause a new pandemic; (ii) using its NS1 protein to impair host immune response. However, little is known on how these two processes occur and whether NS1 could influence the outcome of escape mutants. By using virological and immunological methods, this study will show how viruses use different NS1 to enhance the viral escape mechanism.
