Summary
Herpes simplex virus (HSV) lies dormant within the nerve cell bodies near the spinal cord in most people. Intermittently the virus reactivates and is transported down the nerve to the skin where it causes blisters-ulcers or is shed without causing symptoms. The aim of this grant is to determine how Herpes Simplex virus is transported within nerve cells at the molecular level.

Intermittently the virus reactivates and is transported down the nerve to the skin where it causes blisters-ulcers or is shed without causing symptoms. The aim of this grant is to determine how Herpes Simplex virus is transported within nerve cells at the molecular level. It builds on recent discoveries of a direct interaction between a Herpes simplex viral protein and the nerve cell motor protein which transports essential components down nerves from the spinal cord to the skin. Ultimately we aim to develop inhibitors of this process which might be candidates for further development as antivirals for control of recurrent herpes simplex.Read moreRead less

Summary
Herpes simplex virus (HSV) enters the human body via the skin before entering the termini of nerve cell processes. It is transported along these processes to the body of the nerve cell. HSV lies dormant within these nerve cell bodies near the spinal cord in most people. Intermittently the virus reactivates and is transported back down the nerve cell processes to the skin where it causes blisters-ulcers or is shed without causing symptoms.

Intermittently the virus reactivates and is transported back down the nerve cell processes to the skin where it causes blisters-ulcers or is shed without causing symptoms. The aim of this grant is to determine how HSV is transported and assemblied within nerve cells at the molecular level. Recent discoveries have shown how virus transport in nerve cells is dependent on interactions between specific viral proteins and cellular motor proteins. Such information on viral transport and assembly mechanisms will allow development of inhibitors of these processes which may be candidates for use as antivirals for control of recurrent herpes simplex. In addition, this information will allow the virus to be exploited for use in gene therapy to introduce DNA into human nerve cells to correct genetic abnormalities.Read moreRead less

Summary
Herpes simplex viruses 1 and 2 are important pathogens, causing encephalitis, blindness and severe neonatal infection but they also enhance the acquisition of HIV three-fold. The transport of the virus to and from the periphery to the spinal cord is a key component of their life cycle. Determination of the exact mechanism will assist in a general understanding of nerve function and the development of new strategies for antiviral drugs.

Herpes simplex virus causes genital herpes, severe disease in neonates, cold sores and occasionally fatal encephalitis. It lies doemant within nerve cells near the spine and reactivates intermittently, travelling down nerves to cause the characteristic ulcers in the skin, including the genitals.

It lies doemant within nerve cells near the spine and reactivates intermittently, travelling down nerves to cause the characteristic ulcers in the skin, including the genitals. This grant has two major components. In the first we aim to continue studies which are defining the way in which Herpes simplex viruses assemble within nerve cells. These processes have always been the subject of much debate and have never been properly studied in the nerve cells in which the virus lives. Furthermore the way in which herpes simplex virus enters the processes of nerve cells and moves to the cell body will be studied by similar techniques. Such studies may contribute to the development of herpes simplex virus as a vector for gene therapy for treatment of diseases of the nervous system. The second part of the grant will examine the immune processes that occur in the skin during the early stages of a recurrent herpes simplex lesion. In particular there is a linkage between nerves and the major cells in the skin which present viral antigen to defensive T-cells. This link may provide a route for direct access of herpes simplex virus to these cells. In previous work the viral protein targets in infected skin cells for killer T-cells which infiltrate the skin have been defined. In this grant we also aim to find the stretches of amino acids which are specifically targetted by these cells.Read moreRead less

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.

A sound relationship between Australia and Japan is critical to Australia. Their key relations in trade, foreign policy and cultural exchange require an advanced understanding of Japanese. However, Australia is not producing sufficient numbers of advanced users of Japanese. This project creates and implements strategies to develop more Australian learners into advanced users of Japanese, thus contributing to Australia's knowledge base in language education and applied linguistics. The PhD project will train a well-rounded Australian applied/educational linguist, equipping them with in-depth knowledge of current learners as well as fundamental research tools in both quantitative and qualitative analysis.

Summary
This project aims to establish how mosquito borne viruses such as Ross River and dengue viruses interacts with the human host to cause disease, including how the virus evades the host’s immune response to persist and cause disease for prolonged periods. Knowing how differences in the virus and the host’s immune system interplay to cause asymptomatic to severely disabling disease will assist in devising new treatments and prevention programs to lessen the impact of these diseases in Australia.
