The Molecular Determinants Of Immunological Tolerance

Summary
Autoimmune diseases, such as type I diabetes and multiple sclerosis, are debilitating disorders that impose a massive toll on wellbeing in Australia and worldwide. This fellowship will support research aimed at determining the genes and mechanisms that control autoimmunity. New technologies will be brought to bear to track immune cells throughout their development, maturity and malfunction in disease settings. We aim to uncover new therapeutic targets to prevent and reverse autoimmune disease.
The Role Of Susceptibility Genes And Microbiota In Inflammatory Diseases

Summary
Utilising my background in Immunology I will investigate whether specific genetic mutations can create a susceptibility for dysregulation of the flora and immune system within the gut, thus predisposing an individual to inflammatory bowel diseases (ulcerative colitis and Crohn's disease) as well as non-intestinal inflammatory conditions. These diseases are becoming an increasingly prevalent and serious health burden in Australia. We aim to use this knowledge in order to design specific treatment ....Utilising my background in Immunology I will investigate whether specific genetic mutations can create a susceptibility for dysregulation of the flora and immune system within the gut, thus predisposing an individual to inflammatory bowel diseases (ulcerative colitis and Crohn's disease) as well as non-intestinal inflammatory conditions.

The Control Of Autoimmunity Originating From Somatically Hypermutated B Cells

Summary
Our immune systems are capable of producing long-lived antibodies that can last a lifetime. Sometimes, this powerful process can however become abnormal and result in autoimmune diseases such as lupus. We have recently developed the first experimental mouse model that allows researchers to study this process in great detail. This funding will extend our initial observations by identifying the exact mechanisms by which important regulators of autoimmune disease act.
Prevention Of Autoimmune Diabetes By Immune Tolerance To Proinsulin

Summary
In type 1 diabetes, insulin is the first target of the immune system. Strategies to prevent the immune system targeting insulin in mice early in the disease process work, but it is not clear if such strategies would be effective if applied late. This is important because preventive therapies for human type 1 diabetes are currently feasible only late in the disease process. We aim to address this by removing T cells specific for insulin at different stages of the disease.
How Deletional And Non-Deletional Tolerance Mechanisms Integrate To Prevent Autoimmune Disease

Summary
The body produces millions of immune cells every day to fight infection. Some of these immune cells are defective and dangerous because they can cause autoimmune diseases, like Type I diabetes and multiple sclerosis. To defuse this risk, such immune cells are either caused to die or are inactivated to prevent autoimmunity. We propose to investigate how the processes of immune cell death and inactivation work in health and disease so we may harness these mechanisms to cure autoimmunity.
Understanding The Pathogenesis And Heterogeneity Of Autoimmunity As Failure Of Multiple Steps

Summary
Autoimmune diseases like diabetes, thyroid disease or rheumatoid arthritis affect around 1 in 15 people in Australia. It is clear that defects in a number of different genetic mechanisms can contribute to the development of autoimmunity. But it is currently not clear how these different mechanisms need to interact to prevent the onset of disease. This grant seeks to understand these interactions and how defects in two or more tolerance mechanisms can lead to autoimmunity.
Immune Privilege Of The Hair Follicle: Implications For Alopecia Areata

Summary
The skin, the second largest organ in the body after the skeleton, is of primary importance to the survival of mammalian life. Hair follicles are complex skin appendages, problems of which have an impact on human health and emotional welfare disproportionate to their small dimensions. In this study we will investigate the role of the immune system in the hair loss disease, alopecia areata, one of the most common human autoimmune diseases with the aim of finding more effective avenues of treatmen ....The skin, the second largest organ in the body after the skeleton, is of primary importance to the survival of mammalian life.

Understanding The Critical Mechanisms That Govern Regulatory T Cell Life And Death Decisions

Funding Amount

Summary
Autoimmune diseases impose an increasingly large health burden. Treg cells prevents the immune system from attacking “self” offering the promise of using these cells to restore immune balance in autoimmune diseases. However, there are currently no protocols that reliably modify Treg cell numbers. This study will elucidate the mechanisms that govern Treg cell survival and death, revealing potential molecular targets to manipulate the quality and quantity of Treg cell for therapeutic benefit.
