Brief description Grass pollen is an important cause of allergy (eg. hayfever, allergic asthma) world-wide affecting up to 30% of the population. In Australia, rye grass pollen is a clinically significant health problem costing $83-160 million per annum. At present, the main treatment of seasonal allergy is by pharmacotherapy with the use of crude extracts in specific immunotherapy which often causes large and annoying local skin reactions and may even cause anaphylaxis. Moreover, the use of crude extracts in diagnosis of allergy among some atopic individuals may be inaccurate or ineffective. In the last eight years of my research, I have contributed significantly to the identification, characterisation and molecular cloning of grass pollen allergens. In this proposal, I aim to evaluate recombinant rye grass pollen allergens as standardised and more effective diagnostic reagents and, through the identification and better understanding of the allergenic segments of these proteins, to prepare recombinant mutants of the same proteins which are no londer allergenic. Avaliability of such non-allergenic protein reagents will provide safer immunotherapy in the future. Moreover, since the biolgical role, function and structure of such allergens in the grass pollen still remain largely unknown, I will aim to investigate this with the clinically significant allergens of rye grass pollen. Determination of biological function and structure of such allergens will allow their importance for the pollen-plant to be determined and, since function may be relevant to sensitisation of suceptible individuals to these allergens, these findings will stimulate the development of novel concepts in allergen prevention and therapy.
