Summary
To increase the breadth of HIV prevention strategies, it is imperative that we biologically understand how HIV enters our bodies. Through two unique clinical cohorts, we will determine why circumcision is protective and how a commonly acquired sexual transmitted infection (human papilloma virus) can increase HIV transmission.
The Human Immunodeficiency Virus (HIV) is a virus that infects and kills the cells of your immune system. This infection eventually leads to the Acquired Immune Deficiency Syndrome (AIDS). An important aspect in preventing infection is to study how HIV enters immune cells and how infection spreads. Our lab is researching drugs to block the entry of HIV in immune cells, which can hopefully be used together with existing anti-HIV drugs to slow down the spread of the virus and the onset of AIDS.
Understanding The Establishment Of HIV Reservoirs And Development Of HIV Eradication Strategies

Summary
Understanding why, when, how and at what pace the HIV virus hides and establishes itself in one's body will allow us to design new ways for preventing and eliminating this reservoir of hidden HIV. As a clinician scientist in HIV and infectious diseases, I will drive clinical studies to explore the kinetics of HIV in patients who recently acquired HIV, those who start HIV treatment early, and those chronically infected with HIV so as to investigate novel means to minimise HIV hiding spots.
Characterize The Post-entry Events Of HIV Infection

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.
Developing And Implenting An Ethical Framework For HIV Phylogenetic Analysis In Australia

Summary
Overseas, many countries are using genetic analysis to detect clusters of HIV transmission. This is an important part of reducing the number of new HIV infections, and making sure that all people with HIV receive timely medical care. In partnership with HIV community organisations and public health policy makers, we will provide the first evidence-base for the public health utility of real-time HIV genetic analysis in the Australian setting.
Immune Modulatory Interventions In People With HIV And Cancer: Prevention, Treatment, And Implications For HIV Eradication.

Funding Amount
$344,644.00
Summary
People with HIV are at increased risk of many cancers. New therapies that target the immune system may be useful in treating these cancers, and may also target the cells where HIV persists thereby assisting in eradication of HIV. This research program includes three clinical studies in people with HIV and cancer: one to learn more about their immunity; one to prevent, and one to treat certain cancers by modulating the immune system. Each also explores any effect on HIV eradication.
Improved Health Outcomes For People Living With HIV

Summary
Despite the success of antiviral therapy for HIV infection, HIV cannot be cured and treatment is life long. In addition, there are complications in patients on long term antiviral therapy due to impaired immune recovery. This grant will identify strategies to eliminate HIV from latently infected cells that persist in patients on antiviral therapy as well as identify novel ways to improve the immune response to antiviral treatment for patients with HIV infection as well as patients co-infected wi ....Despite the success of antiviral therapy for HIV infection, HIV cannot be cured and treatment is life long.

Prevention Of HIV-1 Infection By Adeno Associated Virus Vector-delivered Broadly Neutralizing Antibodies Or Antibody-like Molecules

Funding Amount
$875,854.00
Summary
A promising neutralizing molecule has boosted hopes of an HIV vaccine. It remains unknown how well this molecule prevents HIV infection under conditions reflecting “real world” exposure, including exposure to HIV in the form of cells carrying virus or free-floating virus in the presence of semen. We will assess this molecule for their ability to inhibit transmission of HIV-like viruses under these conditions. These experiments will define requirements to protect against HIV infection.
