Summary
Asthma and other allergies are caused by the inappropriate production of IgE antibodies by the immune system. IgE is not produced in response to most infections but the controls that normally prevent IgE production are unknown. We have identified two separate molecules that prevent IgE production during immune responses. In this proposal we aim to investigate how these controls work. This information may help to devise strategies for controlling IgE production and therefore allergic disease.
Methylation-sensitive T Cell Genes And Childhood Food Allergy.

Summary
Australia has the highest reported prevalence food allergy in the world. Despite this, little is known about how allergy develops. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of food challenge proven food allergy with assessment of immune functioning & cutting edge genomics, to extensively characterise the pathways leading to food allergy in children.
Phase I/IIa Trials Of A Novel T-cell Epitope-based Peptide Therapy For Peanut Allergy

Summary
Peanut allergy affects ~2% of the population and is the major cause of food triggered deaths from anaphylaxis. Typically peanut allergy is lifelong. Currently there is no specific treatment. Our vast experience in immunology for house dust mite and grass immunotherapy allowed us to identify critical components of peanut proteins needed as a safe vaccine to build tolerance to peanut foods. Now we will progress this novel and revolutionary vaccine through early phase clinical trials.
Tissue Specific T Cells Mediate Drug Hypersensitivity

Summary
T cells are immune cells that create dangerous and fatal drug allergies affecting the skin. An individual’s genetic makeup only partially explains predisposition to these reactions, we believe the missing link is contained in immune signatures specific to the skin. We aim to identify drug-specific T cells in the skin and develop a sensitive test to screen for rare, dangerous T cells in the blood. This will enable prediction and prevention of severe drug allergy and development of safer drugs.
