Risk Factors For Long-term Chronic Disease Events In HIV-positive Persons: The D:A:D Cohort Study
Funder
National Health and Medical Research Council
Funding Amount
$925,659.00
Summary
The D:A:D Study is a large, international study assessing risk factors for chronic disease events in HIV-positive patients. We know these events, such as heart attacks and cancers, increase with age. And we also know that these events are more common in HIV-positive people. Over the next five years, D:A:D will assess risk factors for chronic disease events in HIV-positive people as they age, and help optimise patient monitoring and management.
The Impact Of HIV Integration Sites On Eliminating HIV Latency

Funding Amount
$778,313.00
Summary
Current antiviral therapy for HIV controls virus production and allows recovery but does not eliminate the silent infection that prevents complete virus elimination and cure. We will examine two ways that HIV can silently infect T cells for differences in the sites at which the HIV DNA inserts into the genome. We will examine the way in which these differences at the genomic level may limit the ability to activate and eliminate persistent infection in memory T cells.
Optimizing The Allocation Of Resources In Response To HIV/AIDS Epidemics

Funding Amount
$724,439.00
Summary
HIV/AIDS is still a major problem around the world, particularly in low- and middle-income countries. This project will support efforts to maximize health impact with limited resources, providing Ministries of Finance and Ministries of Health in developing countries along with global health agencies and funders a key tool and evidence on how to identify the optimal allocation of resources across multiple programs targeting numerous population groups.
HIV Phenotypes Important For The Establishment Of Persistent Reservoirs In The Central Nervous System And Which Impact Neurotropism And Neuropathogenesis
Funder
National Health and Medical Research Council
Funding Amount
$762,492.00
Summary
This grant will determine whether or not the CNS is a reservoir for HIV and identify the cellular targets of persistent infection and type of HIV-1 present.
The primary aim of this grants to determine how HIV spreads through our immune system. The above knowledge will determine key Achille’s Heel moments in the HIV life cycle and thus lead to better therapeutic HIV treatments/prevention.
Characterize The Post-entry Events Of HIV Infection

Funding Amount
$605,190.00
Summary
For HIV to successful infect a target cell, it must properly remove the outer layers of its protective gears (outer viral protein coats) to allow the viral genetic materials to be replicate (duplicate and multiplied) for the generation of their ‘offspring viruses’. This process is known as viral uncoating, and it is arguably one of the least understood areas of HIV. In this proposal, we will use a number of complementary state-of-the-arts research tools to characterize the HIV uncoating process.
HIV Treatment As Prevention: A Longitudinal Assessment Of Population Effectiveness
Funder
National Health and Medical Research Council
Funding Amount
$783,160.00
Summary
This project is a large-scale evaluation of an HIV strategy known as ‘treatment as prevention’ (TasP). Through routine and repeat HIV testing for gay men and early treatment initiation following diagnosis, TasP aims to reduce HIV community infection rates. Through the establishment of a large cohort of gay men in NSW and Victoria, this study will track HIV testing, treatment and management to assess the real-world efficacy of TasP for reducing HIV infections among this at-risk population.
Sytemic And Mucosal Functional Antibodies In Protection Against HIV
Funder
National Health and Medical Research Council
Funding Amount
$559,501.00
Summary
Only one human HIV vaccine has shown any level of protective efficacy. However the mechanisms behind how this vaccine was protective are still not fully understood. Additionally, HIV is primarily transmitted through mucosal sites, however very little is know about vaccine immune responses at these sites. Thus this proposal aims to further define the mechanisms of antibody protection against HIV at both systemic and mucosal locations, in order to guide future HIV vaccine design efforts.
HIV infection is a dynamic process, in which the host immune response tries to control viral growth and keep up with the rapid evolution of the virus. This project assembles an interdisciplinary team of mathematicians and biologists to use a modelling approach to understand the dynamics of viral infection, viral evolution, and immune control in the infected individual. The insights gained from this project will help in the development of new drug and vaccination strategies.
Envelope Glycoprotein Determinants Of HIV-1 Subtype C Tropism And Pathogenicity
Funder
National Health and Medical Research Council
Funding Amount
$657,745.00
Summary
HIV-1 subtype C is the most common subtype of HIV-w worldwide, yet we know comparatively little about how it causes disease in humans. This study will elucidate how HIV-1 subtype C evolves in patients to become more pathogenic over time.
