Resolving Human Immunodeficiency Virus (HIV) Transmission

Funding Amount
$745,213.00
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.
Enterovirus, Vitamin D Status And Inflammation At The Clinical Onset Of Type 1 Diabetes In Childhood

Funding Amount
$410,542.00
Summary
Type 1 diabetes is a serious disease that is increasing in incidence among Australian children. This project will build on an exsisting study to provide new information on the role of enteroviral infection, vitamin D status and the associated inflammatory changes in blood at the onset of disease.
Defective Toll-like Receptor 7 Signalling In Plasmacytoid Dendritic Cells Underlies The Inception Of Virus-associated Asthma

Funding Amount
$552,301.00
Summary
In genetically susceptible individuals, respiratory virus infections are a risk factor for asthma inception and are the most common cause of acute exacerbations. Using a clinically relevant mouse model of disease, this study will investigate whether the altered expression of toll-like receptor 7, a host protein that senses viral invasion, causes the host to mount an inappropriate pro-allergic immune response to the virus.
Exploring The Role Of Respiratory Virus Infections In Childhood Asthma Exacerbations

Funding Amount
$596,649.00
Summary
The PEAK study will explore the reasons children get worse asthma symptoms when they get colds. These reasons examined include the asthma medications taken (or not taken), allergies and exposure to allergens and the type of virus involved. The study follows the children over the whole school term and uses a new way to sample virus by collecting it in the breath, this is more comfortable than old methods and can be done at home.
Prospective Methylation Biomarker Validation Study In Lung Cancer

Funding Amount
$528,281.00
Summary
Lung cancer is a major public health burden with increasing incidence every year. Despite advances, the biology of lung cancer associated with its recurrence either local or distant, with non-smoking lung cancer subtypes and asbestos-related lung cancer remains unexplored.
Intrinsic Host Antiviral Activity Against Pathogenic Filoviruses

National Health and Medical Research Council
Funding Amount
$488,754.00
Summary
Bats are a major reservoir for deadly human viruses including Ebola and Marburg virus. In contrast to humans, bats can be infected with these viruses without showing clinical signs of disease. The reason why bats can co-exist with these viruses is unknown. This study will determine if a bat antiviral molecule contributes to limiting virus release compared to the human version that could reveal strategies to prevent and control these deadly viruses in humans.
Identification Of Host Factors That Restrict Influenza Virus Replication In Macrophages
Funder
National Health and Medical Research Council
Funding Amount
$566,446.00
Summary
Influenza virus infects different cells in the airways, including immune cells (macrophages) and non-immune cells (epithelial cells). Epithelial cell infection results in virus amplification and release whereas macrophage infection leads to virus destruction. This project will identify cellular factors expressed by macrophages that block virus amplification and release. Identification of novel antiviral factors is an important step towards developing strategies to reduce influenza disease.
Identification Of Host Restriction Factors That Block Respiratory Virus Infection

Funding Amount
$956,898.00
Summary
Following inhalation, respiratory viruses can infect and grow in airway epithelial cells. Although immune cells such as macrophages are also susceptible to infection, this is generally abortive and new viruses are not released. This project will identify proteins induced in macrophages that block respiratory viruses and prevent their spread in the airways. We will also define mechanisms by which some virulent strains overcome this block to grow in macrophages.
The Role Of Varicella Zoster Virus In Modulating Cutaneous Infection
Funder
National Health and Medical Research Council
Funding Amount
$555,892.00
Summary
Varicella zoster virus (VZV) causes two skin diseases: chickenpox and shingles. VZV can causes significant morbidity in children and adults and life-threatening disease in immunocompromised people. This project aims to improve our understanding of how VZV affects the function of specialised skin cells to provide information for the development of a better vaccine to lessen the impact of VZV disease on the community.
Identification And Erradication Of Pre-malignant B Cells In The Prevention Of Lymphoma
Funder
National Health and Medical Research Council
Funding Amount
$607,771.00
Summary
B Cell Lymphoma is the most frequent type of non-Hodgkin lymphoma in adults and despite improved treatment, 40-50% of patients succumb to their disease. T cells are critical in the in the prevention B cell lymphoma development. In this project we aim to identify the earliest stages of B cell lymphoma and mechanisms of escape from T cell control with the ultimate aim to translate these findings to human studies to improve disease diagnosis, treatment and prognosis.
