Summary
Autoimmune diseases occur when the body's natural defense mechanisms attack healthy tissues by mistake. It has long been thought that viral infections might play a role in triggering autoimmune disease. Our study aims to find genes that influence the body's response to viral infection and subsequently whether the same genes are involved in autoimmune disease pathology. If the same genes are important in both situations then this will provide evidence that viruses trigger autoimmune disease.
Evaluating The Genetic Contribution To Rheumatic Heart Disease Pathogenesis In Australian Aboriginal And Torres Strait Islander Communities

Summary
Rheumatic heart disease is highly prevalent in Aboriginal people in Australia and leads to early cardiac disease. Despite decades of research, the underlying genetic mechanisms for why it occurs are not well understood. We are conducting a genetic study to better understand why some people are susceptible to RHD and others are not. The study will involve substantial Aboriginal leadership and consultation and will be a model for the conduct of genetic studies in Aboriginal populations.
Most eye diseases have a genetic contribution, whether rare disorders affecting children such as retinoblastoma or congenital cataracts through to common disorders of older people such as myopia, age-related macular degeneration or glaucoma. We will continue our successful research to find genes that cause these diseases and use this to improve patient care and prevent blindness. We will work out how families can use this genetic information to participate in trials to develop new treatments.

Summary
Cytokines or chemical messengers released by cells are essential for controlling immune responses but, in excess, they cause Crohn's disease and arthritis. Our research aims to block cytokine release as a novel way to ameliorate disease. We have identified specific cellular proteins, called golgins, that can be targeted to reduce cytokines. Here, characterization of golgin mediated cytokine transport in cells and in a mouse disease model is necessary to translate these findings for human benefit
Young Adult Myopia: Genetic And Environmental Associations

Summary
Myopia affects 80% of school leavers in the cities of East Asia, 45% of Asian Australian school leavers and is probably on the rise in European Australian adolescents. Increased levels of education and lack of time outdoors are known to increase the risk of myopia. We will examine 2,000 young adults to find the genes that interact with these risk factors. In addition to confirming when these risk factors are most important, identifying molecular pathways opens the avenue of new treatments.
The Aetiology Of Alcohol Use Disorders In Adulthood: A Generational Perspective

Funding Amount

Summary
This study aims to investigate the causes of alcohol problems in adult Australians. We will follow-up participants from a birth cohort study who are now in their thirties. We will assess long term outcomes from in-utero exposure to alcohol and biological, developmental and genetic predictors of alcohol disorders in adulthood. This study also aims to study genetic factors which may be important in the development of alcohol abuse and dependence.
A Novel Role For The IL-2 Pathway In Type-1-diabetes.

Funding Amount
$548,548.00
Summary
Genes encoding IL-2 and its receptor are strongly linked to susceptibility to multiple autoimmune diseases, including type-1-diabetes. Despite the importance of this pathway in the immune system, it is not yet understood how the associated genes affect disease. In this study, a novel function for IL-2 expression by dendritic cells in normal self-tolerance is investigated. The impacts of dendritic cell produced IL-2 expression and linkage to autoimmunity will be elucidated in both mouse and man.
This study is aimed at identifying genetic variants that influence susceptibility to migraine. We plan to use DNA samples already collected from families with multiple migraine affected individuals and sequence a region on the X chromosome that has previously been identified as harbouring a migraine susceptibility gene. This project will identify gene(s) that contain variants contributing to migraine.
Development And Application Of A Mendelian Randomization Framework Aimed At Dissecting The Biological Basis Of Ankylosing Spondylitis And Other Complex Diseases

Summary
Our aim is to identify genes and biological molecules that cause a type of autoimmune arthritis called ankylosing spondylitis. Our approach involves finding combinations of genes that are related to biological molecules of interest and then testing to see whether the gene combination is also related to risk of disease. We hope that our strategy will lead to new drug treatments targeting the condition.
