Summary
Several paramyxoviruses cause respiratory disease in infants, young children and the elderly worldwide. Another paramyxovirus that can be contracted by people from infected horses, Hendra virus, is often fatal. There are currently no vaccines against these viruses, and treatment is generally limited to relief of symptoms. In this project we will uncover how these viruses use human proteins for their growth inside cells, with an aim to develop novel therapeutic strategies.
Defining Key Mechanisms That Underpin Neuropathogenesis Of Varicella Zoster Virus During Herpes Zoster

Summary
Varicella zoster virus (VZV) is a herpesvirus which causes chicken pox and shingles. Shingles affects many elderly people and a major complication is prolonged severe neuropathic pain, often needing follow-up medical care for months to years. Despite its impact on the community, little is known about how this virus functions and causes disease. We aim to improve our understanding of how VZV interacts with nerve cells to provide essential new information for the development of effective treatment ....Varicella zoster virus (VZV) is a herpesvirus which causes chicken pox and shingles.

Chimeric Insect-specific Flaviviruses: A New Generation Of Diagnostics And Vaccines Against Mosquito-borne Viral Disease

$549,937.00
Summary
Dengue, Zika and West Nile are mosquito-borne viruses that cause disease outbreaks world-wide. We will develop safe, cheap and authentic diagnostics and vaccines against these diseases based on novel viruses that only infect mosquitoes. This is a timely paradigm shift for vaccine and diagnostic development. This innovative strategy will have high impact in the field of vector-borne viral diseases and provide a blueprint to develop safe diagnostics and vaccines for other mosquito-borne diseases.
Mechanisms By Which Varicella Zoster Virus And Herpes Simplex Virus Control Host Functions To Enhance Pathogenesis

Summary
Varicella Zoster Virus and Herpes Simplex Virus are alpha-herpesviruses that cause diseases in a majority of the human population. This proposal will explore issues fundamental to disease and pathogenesis of these two closely related herpesviruses, focusing on how these viruses can control host function. In particular, we will define the interactions between these viruses and the natural killer (NK) cell response.
Viruses are considered neither live nor dead, and it is understood that biological process within a virus must occur after it infects a cell. Our work reveals a previous unknown step in HIV known as pre-entry priming. These discoveries challenge our current dogma of how viruses function, and imply this pre-entry priming process is a built in mechanism for HIV to protect itself. This proposal will redefine our understanding of HIV and explore novel HIV vaccine design through these discoveries.
Most individuals infected with hepatitis C virus (HCV) develop progressive liver disease. A vaccine is urgently needed, and needs to mimic the immune responses seen in the minority of individuals who clear infection. However, there are large gaps in our understanding of these responses as most acute infections cause no illness and pass unnoticed. This project will fill these gaps by detailed immunological and virological analysis of a large group of subjects with early infection.
Defining A Novel Mechanism Of Control Of Host Functions By Human Cytomegalovirus That Enhances Viral Pathogenesis

Summary
Human cytomegalovirus (HCMV) remains a significant human pathogen which causes serious and often life-threatening disease in immunosuppressed people such as bone marrow and solid organ transplant patients and in unborn babies infected during pregnancy. This project will define how HCMV controls host defences by actively modifying the cells it infects to create an environment favourable to continued viral infection and disease.

Summary
Conducted by a globally-renown team of HIV scientists and physicians, this clinically-relevant study makes a significant contribution to the emerging field of HIV eradication and cure. Accessing diverse and unique sample sets from HIV patients and applying innovative, ultra-sensitive genetic measurement techniques, the study definitively identifies the bodily reservoirs harbouring persistent HIV so they can be targeted by new therapies, a crucial step for efforts aimed at HIV eradication.
Investigating The Host Determinants Of Viral Clearance Versus Collateral Pathology In Chronic Infection

Summary
Hepatitis B virus has infected over 2 billion people. Some people control the virus but it remains incurable and there is a lifelong risk of liver cancer. Understanding how host cells interact with the virus, the mechanisms the cells use in an attempt to eliminate the virus and the mechanisms the virus uses to sabotage these responses, will provide insights that could lead to therapies. Potential therapies could be applicable to other infections like HIV-1 and tuberculosis.
The Role Of Varicella Zoster Virus In Modulating Cutaneous Infection

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.
