Understanding And Preventing Chronic Disease In People Living With HIV

Summary
Australia’s ageing population is increasingly at risk of chronic diseases such as heart disease and diabetes. For Australians who are living with HIV, these diseases occur more frequently and at an earlier age. I will be investigating the underlying reasons for this increase in risk and will test innovative online systems that help people living with HIV reduce their risk of chronic disease. This work will provide important information for Australians at risk of developing chronic disease.
The Role Of The Innate Immune System In The Immunopathogenesis Of Malaria

Summary
Malaria is common worldwide, affecting 600 million people. As with many infectious diseases, it the severity of a malaria infection is not only dictated by the parasite, but also the body’s immune response to the infection. This study looks at cells that contribute to the immediate immune response in two major clinical syndromes of malaria affecting women and children: cerebral malaria and malaria of pregnancy. By understanding the immune response, we gain insights into how to limit disease.
This project will determine how viruses prevent transmission of messages within cells which orchestrate responses of our immune system to infection and whether our current therapies improve this defect. This knowledge will help us to better understand why our immune system is not able to control chronic virus infection and improve therapies for these diseases.
Dysregulation Of Cytokine Networks: A Key Determinant Of The Pathogenesis Of Cerebral Malaria.

Summary
Malaria is a parasitic disease that kills some 2 million people each year. It affects the Australian region, e.g. PNG and SE Asia. One of the most serious complications is cerebral malaria (CM). It affects the brain and is often fatal. This project will show whether the early meeting of the malaria parasite with the host's immune system determines if the infection will be a mild, resolving one or a severe, possibly lethal one causing CM. This is highly relevant to vaccine development strategies.
Endothelial Dysfunction As A Therapeutic Target In Severe Malaria

Summary
Even with very best drugs to kill malaria parasites, over 15% of patients with severe malaria still die. Their blood vessels are clogged up by malaria parasites. We have shown that the cells lining their blood vessels can't make enough nitric oxide to keep them non-sticky and allow blood through. We want to test whether giving arginine can 1) increase nitric oxide, 2) open up the clogged blood vessels and 3) dampen down other processes that clog up blood vessels in severe malaria.
Understanding, Detecting, Monitoring And Treating Brain Dysfunctions Due To Chronic Immune Diseases

Summary
The role of immune burdens on the brain of middle-aged persons is not well understood. For example the combined brain effects of HIV and cardio-vascular diseases are unknown. Our research is about better understanding those processes using advanced neuropsychology and brain imaging methods. It is also about developing new instruments to detect problems as early as possible, to monitor them accurately and to better treat them in Australia and the Asia-Pacific region.
