Summary
Specialised proteins called MHC class Ia molecules (MHC-Ia) stimulate killer T cells to lyse virus infected cells. In contrast, the function of the closely related MHC-Ib is uncertain. Recent findings have demonstrated that MHC-Ib can also be recognised by T cells and this interaction is important in the control of viral infections. However, despite the similarity to MHC-Ia, it is unclear how this interaction occurs. This project aims to investigate how killer T cells recognise MHC-Ib molecules.

Summary
Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world. Despite this, little is known about how these conditions arise. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of a unique collection of identical twins where one of a pair is sensitive to house dust mite, with cutting edge genomics, to characterise the pathways leading to allergy in ....Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world.

Dendritic cells are essential components of our immune systems. They are located throughout our body and provide the first line of defence against invading microbes. Dendritic cells sense the invader and send out signals to recruit our immune cells to the site of infection. Our research aims to understand how our dendritic cell network is set up and how it functions to promote our immune health.

Summary
Heart attacks and strokes are a major cause of death and disability in Australians. Activation of the renin angiotensin system plays a key role in the development and progression of atherosclerosis, the process that leads to narrowing and obstruction of arteries. In preliminary data we have found a way to block these pathways without affecting the control of blood pressure. We believe that interventions based on these data will be important for the prevention and treatment of heart disease.
Antigen-presenting cells control immune responses. Different types of these cells do different jobs and affect different diseases. We wish to control these processes by determining how the cells live and die. In particular we are interested in controlling the local immune responses during rejection of islet transplantation, which can cure type 1 diabetes.
Spatial And Temporal Dimensions Of Mu-opioid Receptor Signalling: Implications For The Development Of Tolerance

Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
Functional Suicide Of Selected Dendritic Cells By Cytochrome C: An In Vivo Model Lacking Cross-presentation

Summary
Certain white blood cells (dendritic cells) activate the immune system, especially its T cells. Infection of such cells elicits killer T cell responses. However not all infections infect dendritic cells. In such cases, the infectious material is eaten by dendritic cells and moved to certain areas within the cell. This process is called cross-presentation and how important it is during various diseases remains moot. We now have a model of testing this by eliminating these cross-presenting cells.
