Abstract: The present invention relates to the preparation and use of recombinant variants of group 6 allergens of the Poaceae (true grasses), which are characterized by reduced IgE reactivity compared with known wild-type allergens and at the same time substantially retained reactivity with T-lymphocytes.

Abstract: The present invention relates to the provision of the genetic sequence of the major grass pollen allergen Phl p 4. The invention also covers fragments, new combinations of partial sequences and point mutants having a hypoallergenic action. The recombinant DNA molecules and the derived polypeptides, fragments, new combinations of partial sequences and variants can be utilized for the therapy of pollen-allergic diseases. The proteins prepared by recombinant methods can be employed for the in vitro and in vivo diagnosis of pollen allergies.

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.
