Summary
Environmental lifestyle changes are implicated in the concerning increase in allergic diseases such as asthma and allergic diseases over the 25 years. Despite the enormous personal, social and economic cost, the exact causes are not clear. Diet is one of the most important yet unstudied environmental exposures linked to the recent increase in both asthma and allergic disease. Authorities in this area have recommended diet as research priority in the search for allergy prevention strategies.

Despite the enormous personal, social and economic cost, the exact causes are not clear. Diet is one of the most important yet unstudied environmental exposures linked to the recent increase in both asthma and allergic disease. Authorities in this area have recommended diet as research priority in the search for allergy prevention strategies. Allergic diseases result from inappropriate inflammatory immune responses to protein substances such as dust mite (allergens), and it now evident that these patterns of immune responses are commonly initiated before birth. This study will address the influence of maternal diet in pregnancy on the developing human immune system, and how it contributes to the development of allergic immune responses in offspring. One of the most significant dietary changes associated with increasing urbanisation is the increasing intake of pro-inflammatory omega-6 fatty acids (which may promote allergic immune responses) and declining dietary levels of omega-3 fatty acids (which inhibit inflammatory immune responses). Omega-3 fatty acids have beneficial effects in many inflammatory diseases, and are important for healthy pregnancy. It is possible that maternal diets which are becoming increasingly deficient in omega-3 fatty acids may prime the fetus to respond more readily to allergens, and increase the risk of later allergic responses. This study will determine whether increasing dietary omega-3 fatty acids during pregnancy using fish oil supplements, can alter immune responses to house dust mite and other allergens at birth and later infancy. The findings will contribute to our understanding of the relationship between antenatal nutrition and immune development and may lead to dietary recommendations as a cost effective, non invasive strategy to help prevent allergic disease.Read moreRead less
Deciphering IFN Type III, TGF?, IL-10 And Adenosine Pathways In Natural Killer Cells: Enhancing The Innate Anti-metastatic Response Against Breast Cancer Progression

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.
Understanding Immunosuppressive Pathways In Cancer

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.
The Role Of Cytokines In Tumor-induced Immunosuppression

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
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.

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.

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.

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.
