  • Patent number: 9522938
    Abstract: 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.

  • Patent number: 8263090
    Abstract: The present invention relates to the preparation and use of variants of the group 1 allergens of the Poaceae (sweet grasses) which are characterised by reduced IgE reactivity compared with the known wild-type allergens and at the same time by substantially maintained reactivity with T-lymphocytes.

  • Patent number: 6919086
    Abstract: The invention relates to modified recombinant allergen mutants which can be obtained from recombinant allergens which are derived from allergens which can be obtained by extraction from natural raw materials such as pollen of the species Phleum pratense. While these modified recombinant allergens stimulate lymphocytes from patients who are allergic to pollent to proliferate and synthesize cytokines, they exhibit a markedly diminished ability to bind to the IgE antibodies which are present in the serum of the T lymphocyte donors and to grass pollen allergen-specific IgEs and can therefore be used for a specific, made-to-release allergy therapy.
