Summary
Many Australians seek complementary and alternate medicine for the treatment of allergic diseases such as allergic rhinitis. There is evidence that acupuncture treatment is clinically beneficial for the treatment of allergic rhinitis. This project will produce new information that will provide a scientific basis of how acupuncture influences the immune response and modulates inflammation. Broader application to other inflammatory diseases and therapeutic interventions is possible.

Summary
Eczema prevents our children from getting a healthy start to life, increases their risk of developing asthma and hay-fever, and we don’t know how to prevent this condition. Dr. Lowe will help identify causes and the outcomes of eczema and allergic diseases in early life, by using a number of important research projects. This research includes an intervention trial that aims to prevent the development of allergic disease and sensitisation, which Dr Lowe leads

In recent decades, there has been a nearly three-fold increase in the prevalence of allergic diseases such as asthma. Although the reason these diseases have increased in prevalence remains unknown, we suspect the way in which the immune system responds to foreign proteins in the environment may be very important in determining whether an individual develops allergic disease or not.

Although the reason these diseases have increased in prevalence remains unknown, we suspect the way in which the immune system responds to foreign proteins in the environment may be very important in determining whether an individual develops allergic disease or not. How and why individuals with allergic asthma respond excessively and inappropriately to inhalation of a small range of seemingly innocuous proteins (allergens) is a central question in respiratory medicine and allergy. We propose that investigating the way that antigen presenting dendritic cells (DC) respond directly to allergens will shed important light on this issue, as DC are fundamental to our ability to deal with foreign antigens and to generate an appropriate immune response. The overall hypothesis underpinning this proposal is that allergens induce specific responses in DC from individuals with allergic asthma, and that this contributes to the maintenance and amplification of allergic tissue inflammation in this disease. Understanding the ways in which DC respond to clinically relevant allergens will lead to significant progress in understanding the pathogenesis of allergic asthma. This project was recommended for funding last year, but was relinquished when one of the previous co-investigators on last year's grant was awarded a Program grant.Read moreRead less
The aim of this proposal is to test the safety of a novel immunotherapy based on Helicobacter pylori platform technology to treat childhood allergies. Repeated oral administration of killed H. pylori mimics colonisation in the stomach and assists the development of a balanced immune system without the associated disease risk of live H. pylori. To achieve this goal Professor Barry Marshall has assembled a cross-disciplinary team of experts from Industry, Academia and Clinic.

The epithelium lines the airways and is, therefore, constantly exposed to a variety of exogenous antigens, infectious agents and noxious stimuli. This tissue responds to such stimuli by secreting substances that help counteract the insult while simultaneously initiating healing and repair.

This tissue responds to such stimuli by secreting substances that help counteract the insult while simultaneously initiating healing and repair. In this proposal, we will investigate the role of a group of receptors present on the surface of the epithelium which monitor the area surrounding the epithelium for the presence of enzymes which digest host tissue or pathogens. These receptors, known as PAR, sense their suroundings by binding the protease, a process which then triggers the cell to respond in an appropriate way by releasing cytokines and mediators. There are 4 PAR, each with different properties, and are present on many cells of the body. However, little information about their role on epithelium exists. Although we have shown them to be upregulated in the epithelium in the socio-economically important disease, asthma, their function in this disease remains elusive. We will, therefore, initiate studies to define their role in inflammation, healing and repair as this information may lead to a better understanding of their role in disease which may then translate into better treatment.Read moreRead less
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
