Summary
Excessive cell death can lead to chronic inflammation and autoimmunity. Cells can die by different mechanisms including necroptosis which causes inflammation, and apoptosis which does not. Recent studies show that caspases, a component of the apoptosis pathway which accelerate cell death, also prevent immune activation by dying cells. I will investigate whether caspases contribute to autoimmune disease and whether caspases can dampen the inflammation that occurs during necroptotic cell death.
The Role Of Self Reactive T Cells In The Normal TCR Repertoire

Summary
The immune system is highly regulated and sophisticated in order to distinguish foreign invaders from our own body. Once control is lost in this system, mistakes can happen, and autoimmunity, attack of ones self may result. Surprisingly potentially dangerous ‘fighter’ T cells can be readily found in healthy individuals whom are free from autoimmunity. The aim of this project is to understand how we can survive with these potentially harmful T cells around and what may activate them.
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.

In Vivo Investigation Of Human PR3 Transgenic Mice: A Novel Animal Model To Understand The Role Of PR3 In Chronic Inflammation And Autoimmune Vasculitis

Summary
Granulomatosis with polyangiitis (GPA) is a form of vasculitis and is associated with antibodies directed against proteinase 3 (PR3). PR3 is expressed in neutrophils, monocytes and macrophages and has a number of well-characterized pro-inflammatory functions. The aim of this project is to understand the role of PR3 in inflammation and autoimmune vasculitis in vivo. This will be achieved using a transgenic mouse model expressing human PR3.
The Development Of Selective And Potent Kv1.3 Ion Channel Blockers For The Treatment Of Multiple Sclerosis

Summary
Building on the well-established path of developing drugs from Nature, the amplification of some unusual qualities of a naturally-occurring substance, khellinone, could lead to new treatments for autoimmune diseases such as multiple sclerosis and diabetes. Designed variants of khellinone are known to be very effective at preventing the destructive impact of the body's own T cells on the central nervous system that occurs in autoimmune disease.
