Summary
Pregnant women are known to be highly susceptible to certain viral infections, especially influenza, which results in severe illness and even death. The reason for this transitory susceptibility are unknown. We have found that a protein, Syncytin, has the ability to impair maternal immune responses to influenza We now will determine how it does this and discover potential interventions to reverse these effects.

Summary
We have developed a novel animal model by which to study arthritic disease caused by insect-transmitted viruses known as arboviruses. The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal.

The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal. The production by our immune systems of soluble mediators (cytokines-chemokines) and antibodies is an overwhelming positive aspect of our physiological response to infection by microbes. Protection from disease by these immune compounds can happen naturally, or the body's ability to produce these factors can be exploited to our benefit via the administration of vaccines. However, these factors can also be detrimental to the host contributing to severe disease. For instance, work performed almost 40 years ago showed for the first time that under particular conditions, antibodies against viruses can enhance infection, instead of inhibiting infection as normally seen. In the intervening years work by scientists all over the world has associated antibody-dependent enhancement (ADE) of infection to many types of viruses; ADE is even thought to be a risk factor to serious disease with dengue virus, and has been shown in vitro for the AIDS virus and Ebola virus. We have recently discovered a molecular mechanism which explains how antibody enhances viral infection in vitro. In studies on immune cells infected with Ross River Virus (RRV) we found that infection helped by antibody resulted in the specific disruption to the production of cellular chemicals which are toxic to viruses. Are these mechanisms of antibody-enhanced infection also found in animals? Will such mode of infection cause enhanced disease and tissue pathology (arthritis) in animals?Read moreRead less

Summary
Herpes simplex viruses 1 and 2 cause common diseases such as genital herpes and, occasionally, neonatal deaths and encephalitis and predisposes to HIV infection. New antiviral strategies are required for resistant viruses for control. These aims will be facilitated by understanding how HSV is transported down nerves and across into skin. In this study, we will define how a key viral protein plays a major role in assembly of the virus at the tip of the nerve before it enters skin.

The study will investigate why humans cannot eradicate particular viruses (HIV-AIDS, cytomegalovirus and herpes simplex virus), the long term effects of these viruses and ways to improve control. Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease.

Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully persist within reservoirs in the human body. The research program brings together a group of 6 leading scientists and clinicians located at 3 sites in 2 Australian cities. The team is comprised of experts in the study of HIV-AIDS, cytomegalovirus and herpes simplex virus who will combine their knowledge and expertise to speed up the process of research on these viruses that are of major health importance. Studies will also utilise a number of cutting edge technologies that now make it possible to much more rapidly and precisely determine how viruses cause disease. Advances in our understanding of how viruses persist may form the basis for treatments aimed at controlling persistent infections and the serious diseases caused by these viruses.Read moreRead less
