Summary
HIV-AIDS is the fourth leading killing disease worldwide, with the disease burden shifting towards women. Study of the HIV life cycle in cells known to be targetted during HIV transmission is key towards designing additional preventative measures in the form of topical gels known as microbicides. Mapping of the basic pathways of viral transport within such cells, will aid further drug discovery and-or appropriateness of use of existing drugs in microbicide formulations.
Modelling The Interaction Between Sexually Transmitted Infections And HIV Transmission To Inform Public Health Policy

Summary
Other sexually transmitted infections (STIs) increase the risk of acquiring or transmitting HIV. Using mathematical models the population level effects of this increased risk will be investigated. This work will inform the design of effective and efficient STI treatment programs that aim to reduce the number of HIV infections in Australian gay men, prevent HIV epidemics in Aboriginal and Torres Strait Island communities, and slow the growth of HIV in Papua New Guinea.
The Interaction Between Sexually Transmissible Infections And Human Immunodeficiency Virus Infection In Homosexual Men

Summary
This project examines the inter-relationship between HIV infection and sexually transmitted infections (STIs) in homosexual men. The overall goal of the projet is to inform the development of STI prevention and treatment strategies which may be important in reducing HIV incidence in this population. Homosexual men comprise over 80% of people diagnosed with HIV infecton in Australia, and in many developed nations are one of the largest groups affected by HIV.

The overall goal of the projet is to inform the development of STI prevention and treatment strategies which may be important in reducing HIV incidence in this population. Homosexual men comprise over 80% of people diagnosed with HIV infecton in Australia, and in many developed nations are one of the largest groups affected by HIV. Rates of other STIs are also increased in homosexual men. Currently, HIV rates are increasing in Australia and in many developed countries. We are in need of new and effective methods of HIV prevention. Data in heterosexuals suggest that where STIs are common, the early detection and treatment of these infections may help reduce HIV incidence. There are few data on this relationship in homosexual men. We propose to utilise an existing Sydney cohort of homosexual men to collect data on biologic tests for STIs, history of recent diagnosis of STIs, and symptoms, to allow a comprehensive description of the epidemiology of STIs and their overlap with HIV. The quality of data on the interaction between HIV and STIs in this cohort will be superior to any previously collected in homosexual men, as it will include data on self-reported doctor diagnosed illness, state of the art biologic testing, and symptom data, for the full spectrum of important STIs. The results of this study will be helpful in determining strategies for HIV and STI screening, education and control in the population which comprises the great majority of cases of HIV infection in Australia, and one of the largest risk groups for HIV infection in the developed world. Screening coupled with treatment of asymptomatic STIs may be an effective new approach to HIV prevention in this population.Read moreRead less
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.
HIV Treatment As Prevention: A Longitudinal Assessment Of Population Effectiveness

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.
Defining The Interaction Of HIV With The Interferon System In Initial Mucosal Infection

Funding Amount
$867,716.00
Summary
Very early after virus exposure, immune cells secrete interferons that help limit the spread of viruses within the body. We will investigate the complex interplay between HIV and the interferon system, especially how HIV inhibits the early induction of interferon to aid its spread and then how the body later restores the interferon response. We will also examine how HIV manipulates the interferon system in order to persistent latent reservoirs within tissues.
Resolving Human Immunodeficiency Virus (HIV) Transmission

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.
Elucidation Of Immune Mechanisms Underlying HSV Vaccine Development

Funding Amount
$573,993.00
Summary
HSV-1 and -2 causes genital herpes, cold sores, encephalitis, potential fatal neonatal herpes, keratitis and blindness as well as severe disease in transplant patients. HSV infection also enhances the acquisition of HIV by 2-3 fold. Investigating the mechanism of immune response to HSV infection or components of HSV will assist in understanding immune control of HSV, HSV vaccine development, and assist in reducing in HIV spread.
Developing And Implementing Systems To Optimise Treatment, Care And Support Among People Diagnosed With HIV

Funding Amount

Summary
Immediate treatment of people diagnosed with HIV infection has become a key public health intervention, based on recent evidence confirming treatment suppresses the virus to undetectable levels, and effectively eliminates the risk of transmission to sexual partners. Our partnership will identify and address barriers to accessing specialist HIV care and starting treatment among people recently diagnosed with HIV, and will contribute to Australia’s goal of ending HIV transmission by 2020.
