Summary
Chronic infections produced by pathogens such as HIV, overwhelm our immune system leading to an exhausted state where cells responsible for the clearance of invading microorganisms are unable to respond effectively. We have recently identified a highly promising therapeutic target that enhances immune effector function. We seek to understand the underlying mechanism, and to explore its therapeutic potential for use as a common platform to treat diverse infections.

Summary
Follicular helper T (Tfh) cells are a type of immune cells essential in antibody production. Preliminary data shows that SIV infects macaque Tfh cells. In this project, we will investigate the mechanisms by which SIV enters into Tfh cells, and test the susceptibility of human Tfh cells to HIV-1 infection ex vivo. This project will enable understanding of the fate of Tfh in HIV infection and its role in HIV host defense and it may facilitate the design of vaccine against HIV.

Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
Where It All Begins- Exploring Dendritic Cell Control Of Viral Infection And Cell Development In The Bone Marrow Of Mice And Man.

Summary
The bone marrow (bm) is the birthplace of all blood cells that fight infection in the body. Dendritic cells (DC), essential for starting immune responses, are found in the bm but the exact types and their functions are unknown. I plan to investigate the DC types that reside in the bm and explore their role in inducing immune responses and in influencing the development of cells from the bm with potential attributable benefits for stem cell transplant and vaccine design.
Encephalitis, or inflammation of the brain tissue, is a complex disease and children are the most commonly affected. The Australian Childhood Encephalitis (ACE) Study, a national surveillance study, aims to describe the burden and characteristics of this disease in Australian children. The Discovery of Infectious aetiologies in Cryptic Encephalitis (DICE) study aims to perform cutting edge diagnostic tests and provide a new understanding of the infectious basis to encephalitis in Australia.
Analysis Of Proinsulin-epitope Specific CD4+ T Cells In Blood Of People With Type 1 Diabetes

Summary
Type 1 diabetes (T1D) is an incurable autoimmune disease characterised by T-cell mediated destruction of insulin-secreting cells of the pancreas. Development of preventative therapies is hampered by paucity of knowledge regarding the targets of the autoimmune T-cell response. We have recently identified epitopes ‘seen’ by islet-infiltrating T-cells, located in proinsulin. Our aim is to examine proinsulin-specific T-cell responses in the peripheral blood of people with and without T1D.
Targeted Molecular Therapies And Predictive Biomarkers In A Novel Orthotopic Xenograft Model Of Oesophageal Carcinoma

Summary
Oesophageal cancer is the most rapidly increasing malignancy in Western society. This disease often presents in advanced stages with poor response to established medical and surgical therapies. Our aim is to develop a novel mouse model of oesophageal cancer, allowing us to tailor cancer-inhibiting molecular treatments to individual patients by predicting therapeutic success or resistance with the use of cellular markers identified in our animal mode.
TOLL LIKE RECEPTORS AGGRAVATE GLOMERULONEPHRITIS AND KIDNEY INJURY IN RENAL VASCULITIS

Summary
Anti neutrophil cytoplasmic antibody associated vasculitis (AAV) is a significant cause of morbidity and mortality. My thesis will explore the role of Toll Like Receptor (TLR) 2 and TLR9 in the initiation and pathogenesis of AAV and the therapeutic potential of TLR2/9 inhibitors. I will use both a murine experimental model and human kidney biopsy samples in this work. My thesis will further define the critical molecular events that underlie the disease whilst addressing potential new therapies.
Pro-apoptotic Therapies For The Treatment Of Mycobacterium Tuberculosis Disease And Latent Infection

Summary
Programmed cell death has an important role in our ability to fight organisms. Upon infection, processes result in activation of death-inducing cascades, resulting in death of cell and pathogen. M. tuberculosis, an escalating health problem, has developed mechanisms to prevent this, leading to latency. This study, which uses mouse M.tb models, hypothesises that reversal of these mechanisms, using drugs currently in trial in leukaemia (ABT-737 & BV6), may lead to clearance of infection.

Recurrent episodes of prolonged wet cough in children, termed Protracted Bacterial Bronchitis (PBB), may cause long term lung damage. I am a paediatric respiratory and sleep subspecialist in training. Through our research we will investigate for abnormalities in the immune system of children with recurring episodes of PBB and follow these children over a 2 year period to determine whether they go on to develop lung scarring. We will also be looking for a link between PBB and obstructive sleep pr ....Recurrent episodes of prolonged wet cough in children, termed Protracted Bacterial Bronchitis (PBB), may cause long term lung damage.
