Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. We have shown that the cytokine IL-23, plays an important role in cancer initiation, growth and development. My project aims to characterize the cells that produce IL-23 in the cancer microenvironment and define how it suppresses cells of the immune system. A greater understanding of this cytokine’s mechanism of action will enable the rational improvement of treatments for patients with cancer

Summary
This project will determine whether one or more factors produced in tumours (eg. cell hormones and metabolites) inhibits NK cells from controlling breast cancer spread using the best available mouse tumour models. We will use genetics to specifically delete response to these factors by NK cells. It is a completely novel approach and this information will allow for the more rational design of cancer treatments following surgery and local radiotherapy and/or chemotherapy.
Professor Godfrey is an immunologist with a long standing history as a pioneer in the study of a specialised type of white blood cell, known as NKT cells. NKT cells are activated in response to lipid-based molecules that are thought to alert the immune system, via NKT cell activation, to the presence of infectious agents or other abnormalities.

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. Suppression can be mediated by cells of the immune system, or cancers themselves. My project aims to investigate 3 suppressive pathways and determine their hierarchy in different mouse models of cancer using mouse genetics and antibody-based treatment approaches. Understanding these processes ongoing in the cancer environment will allow the design of more effective cancer therapies.
Understanding Immune Regulation During Parasitic Diseases.

Summary
Chronic infectious diseases such as HIV/AIDS, tuberculosis, malaria and leishmaniasis are responsible for significant morbidity and mortality. They are all characterised by severe immune dysfunction. We will study a parasitic infection to identify important immune cell populations and molecules that promote chronic infectious disease. This knowledge will enable the development of better treatments and vaccines for range of infectious diseases that affect people in many parts of the world.

Summary
This research aims to understand how the Malaria parasite, which causes one of the world’s deadliest diseases, evades immunity. It will provide a significant advance in our knowledge of immunity against malaria and impact on current strategies to develop an efficacious vaccine or treatment for malaria.
Investigation Of Molecular And Cellular Determinants Of Immune Related Adverse Events Following Treatment With Immune Checkpoint Inhibitors

Summary
Novel immune-based treatments for advanced, incurable, cancer have significantly improved patient survival. Although these treatments have proven highly effective, they are associated with the unpredictable development of severe and sometimes life-threatening autoimmune disease. We aim to discover ways to predict and potentially prevent these complications by identifying genetic risk factors and markers in blood samples. If successful, this will be a ground breaking advance in cancer care.

Chronic inflammatory diseases are an enormous and growing health problem. There is a continuing search for improved and more targeted treatments.

There is a continuing search for improved and more targeted treatments. We have been studying a cytokine called interleukin-4 which can suppress the production by blood cells of many of the inflammatory mediators that initiate and maintain inflammation. With the recognition that interleukin-4 has this anti-inflammatory activity on blood cells, there was considerable optimism that this molecule may not only be a natural regulator of inflammation but also used in immunotherapy. However we do not know how this molecule downregulates inflammatory blood cells. It will be necessary to know this if it is to be used in human gene therapy for treatment of inflammatory diseases. Cells must be activated before a molecule which is anti-inflammatory can be effective. Different cell types from different inflammatory sites will be studied to better characterise different activation pathways. How interleukin-4 regulates these pathways will be studied. Once identified, treatments based on the properties of interleukin-4 may be designed-optimised.Read moreRead less

Summary
T cells are the sentinels of our immune system continually scanning our tissue for abnormalities and eliminating threats in many forms. They are our second and last line of defence against microorganisms and cancer. Unfortunately, T cells can also cause harm through accidental crossreactvity or overzealous function. My work is directed at understanding how T cells work and how they can be controlled using drugs and gene therapy. If we can ‘tune’ the power of this master immune lineage we can unl

Summary
Immuno-modulators utilize the patient’s own immune system to eliminate or slow the growth of cancerous cells. We have identified a novel immuno-modulator which could be a significant player in immune-modulation therapy for the treatment of cancer. We will use the development grant to develop a product which has significant potential to be the next generation treatment for cancer.
