Phl p 5a derivatives having reduced allergeneity and retained t-cell reactivity

摘要

The present invention relates to the preparation and use of variants of the group 5 allergen of the Pooideae which are characterised by reduced IgE reactivity compared with the known wild-type allergens and at the same time by substantially retained reactivity with T lymphocytes. These hypoallergenic allergen variants can be employed for the specific immunotherapy (hyposensitisation) of patients having grass pollen allergy or for the preventative immunotherapy of grass pollen allergies.
