Hendra virus (HeV) cause a disease transmitted from bats to horses which in turn infect humans and other horses. There are no drugs or vaccines for HeV. Since humans are infected by inhalation, a vaccine that can generate antibody in the lung and protect from infection will be ideal. We have found that a natural sugar called mannan used with virus proteins and administered via the nostrils to generate such responses. In this project we will prepare this vaccine and use it in a mouse model of HeV ....Hendra virus (HeV) cause a disease transmitted from bats to horses which in turn infect humans and other horses.

Dengue is a viral infection that is transmitted by mosquitoes in tropical regions of the world, including in northern Australia. For doctors who treat dengue patients, a major unmet need is the ability to predict which patients will develop severe complications and need highly specialized supportive care. This proposal will seek to address this unmet need by examining whether markers of human genetic variation can be used to predict those patients at risk of severe dengue.
Harnessing Lipid-reactive Immunity To Combat Mycobacterium Tuberculosis Infection

Funding Amount

Summary
Critcial to the survival of Mycobacterium tuberculosis, the causative agent of tuberculosis (TB) is its unique waxy (lipid)-rich cell wall. This proposal aims to target components of its cell wall to devlop novel therapeutic strategies. Specifically, the Australian-Singapore alliance will examine how the immune system "sees" lipid based antigens from M. tuberculosis, and then will ultimately use this information towards the devlopment of novel lipid-based vaccines.
Understanding Pathogenicity And Immunity In An Encephalitic Mouse Model Of Hendra Virus Infection
Funder
National Health and Medical Research Council
Funding Amount
$572,342.00
Summary
Our understanding of Hendra virus infection and immunity is extremely limited and has been hampered by a lack of appropriate animal models of disease and reagents. This Project will employ a newly-established mouse model to study encephalitis, the most life-threatening manifestation of this infection. We will use unique, state-of-the-art infrastructure and a plethora of mouse-specific reagents to investigate the mechanisms involved in regulating the host response to infection.
