Summary
The HealthNuts study of 4600 infants is the world’s first comprehensive population-based study of food allergy with objective measurement of true food allergy and will enable us to understand better the natural history of allergic disorders including food allergy, asthma, eczema and allergic rhinitis and the interplay of risk factors for development of these conditions in the first 6 years of life. The study will have important implications for clinical guidelines and public health policy.

Summary
Food allergy (FA) has risen to epidemic proportions in recent times and Australia has one of the highest rates in the world. FA is most common in children under 5 years, yet adolescents are at the greatest risk of death from food-related anaphylaxis. We don’t know why this is the case. Our research will describe FA prevalence and will assess the factors placing FA adolescents at high risk of severe allergic reactions. Findings will influence policy for management of FA and anaphylaxis.
The prevalence of food allergy (FA) has risen dramatically in the last 20 years. Strong evidence suggests that undetermined lifestyle factors are central to this modern phenomenon. We will develop a CRE in Paediatric FA and Food-related Immune Disorders, providing international leadership in public health initiatives to stem the tide of FA and related disorders. We are uniquely placed to provide evidence-based guidelines that will inform public health policy and clinical care of patients.
A Population-based Cohort Investigation Of Postnatal Microbial Experience, Immune Programming And Allergic Disease Risk

Summary
This is a population-based longitudinal investigation of the early life host-environment interactions that influence development of the immune system, and the risk of allergic disease. Importantly, this is one of the first studies designed to examine epigenetic programming of the infant immune system in the population setting. Thus we will be able to conduct robust tests of several critical hypotheses that will inform the prevention of allergic disease.
Inflammatory skin disorders, such as psoriasis and dermatitis, are responsible for a large burden of human disease and affect people across alldemographics. Knockout (KO) of TNF signalling members in mice is known to induce skin inflammation. This project proposes to use these genetic mouse models to investigate how and why disruption of particular TNF superfamily members leads to disease and potentially identify new targets for treatment.
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier

Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

Summary
Excessive sunlight can cause melanoma, a serious type of skin cancer. However, there are other factors including a person's genetic make-up that are thought to put some people at higher risk. Many 'healthy' people have small changes in their genes that might make them more likely to develop melanoma. We need to know more about these genetic factors. Our study will investigate how particular small genetic changes influence a person's likelihood of developing melanoma.
Predictors And Consequences Of Allergies That Impact On Children Getting A Healthy Start To Life:a Prospective Study

Summary
Allergic diseases prevent Australian children getting a healthy start to life by causing long term illnesses. This group of diseases includes asthma, hay fever, eczema and food allergies. Half of all Australian children are born into families with a history of these conditions and these children are at increased risk. Some of these children develop allergies while the others do not. It is also known that allergic conditions change over time, but we have no information on causes of these changes. ....Allergic diseases prevent Australian children getting a healthy start to life by causing long term illnesses. This group of diseases includes asthma, hay fever, eczema and food allergies. Half of all Australian children are born into families with a history of these conditions and these children are at increased risk. Some of these children develop allergies while the others do not. It is also known that allergic conditions change over time, but we have no information on causes of these changes. For example some infants with eczema continue to have eczema or develop hay fever and asthma, while others do not. The aim of this study is to determine what factors cause allergies and what factors influence these changes. This will provide evidence to guide health policy and clinical practice. Looking at the different conditions in family members over time is a good way to answer these types of questions, because parents and siblings share similar exposures, but not all the same genes. This helps to disentangle the effects of the environment and genes. The Melbourne Atopic Cohort Study (MACS) is amongst the world�s major studies on the development of allergies. MACS commenced in 1991-94 by recruiting 620 babies prior to birth. Only infants born into families with a history of allergic disease were included. MACS is unique because all family members and the home environment were assessed at the time of birth of the child. These children have been followed regularly over the first ten years of their life. The MACS now provides a unique opportunity to conduct a family study that can examine genes, childhood environment and individual risk factors for allergies. This will also allow exploration of the impact of allergies on families and the health care system, and how we can reduce that impact. Such information will provide evidence to guide health care policy and clinical practice. Also, the current study will provide a platform for future studies to investigate the progression of allergies in this family cohort. This will be the world's only longitudinal family follow-up of allergies that spans all of childhood. It will assist in reducing the impact of these common conditions, and the findings will be original and significant not only in Australia but also internationally.Read moreRead less
Fighting Epidermal Skin Cancers By Targeting Epidermal Clones That Accumulate Mutations

Summary
Common skin cancers such as basal and squamous cell carcinomas (BCC and SCC) are by far the most frequent cancer worldwide and require over a million interventions per year in Australia. This project will identify the skin cells that are most susceptible to give rise to cancer if excessively exposed to the sun and explores ways to prevent cancer formation. This will inform on new strategies to prevent new skin cancer development.
