Summary
We plan to translate our recent discoveries on human gene variants and molecules produced by immune cells (follicular T cells) into effective therapies for autoimmune diseases. This will involve understanding the mechanisms by which the genes and molecules regulate immune tolerance, stratifying patients with autoimmune disease using newly identified biomarkers, trialling existing biologicals according to affected molecular pathway, and taking novel targets through to commercialisation.
Understanding Immunity To Influenza B Viruses For A Rationally Designed Universal Vaccine

Summary
Influenza B viruses (IBV) circulate annually and are particularly prevalent and severe in children. However, IBV remain largely understudied. Our immune system provides protection against IBV via a variety of mechanisms. This study will characterize the immunity to IBV and dissect host-virus interactions which provide protection from IBV infection. This project will inform the rational design of novel vaccines eliciting universal immunity to IBV, with an ultimate goal of controlling IBV.
Understanding And Harnessing Immunity To Fight Melanoma

Summary
Novel cancer therapies aimed at stimulating the body's immune defence have shown remarkable clinical success, although the immune mechanisms that can prevent disease recurrence remain poorly understood. Our study will fill this important gap in knowledge by elucidating the mechanisms of efficient immune protection from skin cancer and metastatic disease. As such, our results will be important for the development and improvement of innovative cancer therapies.
Characterization And Targeting Of Precursor Exhausted T Cells (TPEX) For The Treatment Of Chronic Infection And Cancer

Summary
The recent discovery of precursor exhausted CD8 T cells (TPEX) has not only allowed us to conceptualize our understanding of how chronic T cell responses are maintained over long periods of time, but also resulted in a new understanding of the mechanisms underpinning checkpoint inhibition. I will undertake critical characterization of these TPEX in chronic viral infections with the goal to reveal phenotypic and functional properties, which will serve as potential novel targets for immunotherapy.
The Role Of Mucosal-Associated Invariant T Cells In Protective And Aberrant Immunity

Summary
Despite their prevalence and potential therapeutic value, MAIT cells remain the least studied of all T cells. This program seeks to do paradigm shifting research into the role of MAIT cells in protective immunity to microbes and allergies. Thereby this project will significantly advance fundamental knowledge on MAIT cell biology and could furnish novel immunotherapeutic agents with an enormous potential as alternatives to microbial and allergy treatments, areas of tremendous clinical need.
Targeting Vitamin-reactive T Cells For Enhanced Immunity

Funding Amount

Summary
A specialised set of T cells called mucosal-associated invariant T (MAIT) cells react against bacteria and yeast, and reside at mucosal sites where the body's immune defences are often breached, e.g. respiratory tract and intestinal mucosa. This study seeks to define the molecular signals driving the function of MAIT cells, particularly during infections. This information may lead to methods tailored to manipulating MAIT cells therapeutically.
Controlling The Haematopoietic System To Treat Cardiovascular Disease

Summary
The Murphy laboratory studies how the body makes blood. In people with heart disease too much blood is made that quickens the progression of heart disease. Slowing the production of blood back to normal seems to slow this progression. In this project, they will discover how and why more blood is made and ways to limit this.
Understanding Immune Responses To Severe Influenza Virus Infection And Vaccination In Humans

Summary
During influenza virus infection, people acquire robust and long-lasting immunity. However, current influenza vaccines elicit only transient immunity. I will define optimal responses in different immune cell types after natural infection versus vaccination; understand why some people fail to generate protective antibodies to the vaccine; and identify key biomarkers aimed at reducing influenza disease impact in high risk groups. This work will improve future influenza vaccination regimens.
Natural killer (NK) cell posses the ability to detect and kill transformed or stressed cells such as tumour cells. My recent data show that NK cells are required for efficient immunotherapy responses by enhancing the global immune response to cancer and preventing tumour cells from metastasising to vital organs. I propose to identify novel pathways and develop new therapeutic approaches to exploit NK cell anti-tumor function and improve cancer immunotherapy response rates in patients.
