Definitions
- the present invention relates to the provision of DNA sequences of group-4 major allergens from cereals (Triticeae).
- the invention also includes fragments, new combinations of partial sequences and point mutants with hypoallergenic activity.
- the recombinant DNA molecules and the deduced polypeptides, fragments, recombinations of partial sequences and variants can be used to treat pollen allergic diseases.
- the recombinantly produced proteins can be used for the in vitro and / or wVo diagnostics of pollen allergies.
- Allergies of type 1 have worldwide significance. Up to 20% of the population in industrialized countries suffer from conditions such as allergic rhinitis, conjunctivitis or bronchial asthma. These allergies are caused by airborne allergens (aeroallergens) released from sources of various origins such as plant pollen, mites, cats or dogs. Up to 40% of these type 1 allergy sufferers, in turn, show specific IgE reactivity with grass pollen allergens, including cereal pollen allergens (Freidhoff et al., 1986, J. Allergy Clin Immunol 78, 1190-2001). Of particular importance among the pollen allergens are the allergens of rye.
- the type 1 allergy-causing substances are proteins, glycoproteins or polypeptides. These allergens react after absorption via the mucous membranes with the sensitized persons at the Surface of mast cell-bound IgE molecules. If two IgE molecules are cross-linked by an allergen, this leads to the release of mediators (eg histamine, prostaglandins) and cytokines by the effector cell and thus to the corresponding clinical symptoms.
- mediators eg histamine, prostaglandins
- the allergens from the pollen of different species of the grasses family are divided into groups that are homologous with each other.
- the molecules of major allergen group 4 exhibit high immunological cross-reactivity with each other both with mouse monoclonal antibodies and with human IgE antibodies (Fahlbusch et al., 1993 Clin Exp Allergy 23: 51-60, Leduc-Brodard et al. , 1996, J. Allergy Clin Immunol 98: 1065-1072, Su et al., 1996, J. Allergy Clin Immunol 0 97: 210, Fahlbusch et al., 1998, Clin Exp.
- Peptides have also been obtained and sequenced by proteolysis from group 4 allergen of the subtropical Bermuda grass (Cynodon dactylon): KTVKPLYIITP (SEQ ID NO 17), KQVERDFLTSLTKDIPQLYLKS (SEQ ID NO 18), TVKPLYIITPITAAMI (SEQ ID NO 19), 0 LRKYGTAADNVIDAKWDAQGRLL (SEQ ID NO 20), KWQTVAPALPDPNM (SEQ ID NO 21), VTWIESVPYIPMGDK (SEQ ID NO 22), GTVRDLLXRTSNIKAFGKY (SEQ ID NO 23), 5 TSNIKAFGKYKSDYVLEPIPKKS (SEQ ID NO 24), YRDLDLGVNQWG (SEQ ID NO 25), SATPPTHRSGVLFNI (SEQ ID NO 26), and AAAALPTQVTRDIYAFMTPYVSKNPRQAYVNYRDLD (SEQ ID NO 27, Liaw et al.,
- the DNA and protein sequences of the mature allergens according to SEQ ID NO 1-10 are preceded by a signal sequence.
- the coding region ends with the TGA or TAG stop codons in the DNA sequences.
- DNA sequences of the pollen allergen allergens See c 4, Hör v 4 and Tri a 4, according to SEQ ID NO 1, 3, 5, 7, and 9, are provided.
- the present invention therefore relates to DNA molecules selected from the nucleotide sequences according to SEQ ID NO 1, 3, 5, 7, and 9.
- the invention further relates to the DNA sequences according to the invention homologous sequences or corresponding DNA molecules of group 4 allergens from other Poaceae such as Lolium perrena, Dactylis glomerata, Poa pratensis, Cynodon daetylon and Holcus lanatus, due to the existing hybridizing sequence homology with the novel DNA sequences under stringent conditions, or the allergens according to the invention have an immunological cross-reactivity with respect to he sc.
- Poaceae such as Lolium perrena, Dactylis glomerata, Poa pratensis, Cynodon daetylon and Holcus lanatus
- the invention also includes fragments, new combinations of partial sequences and point mutants with hypoallergenic activity.
- the invention therefore furthermore relates to corresponding subsequences, a combination of partial sequences or exchange, elimination or elimination mutants which code for an immunomodulatory, T cell-reactive fragment of a group 4 allergen of the Poaceae.
- a classical approach to the effective therapeutic treatment of allergies is Specific Immunotherapy or Hyposensitization (Fiebig, 1995, Allergo J. 4 (6): 336-339, Bousquet et al., 1998, J. Allergy
- a c innovative preparations used in the form of allergoids are chemically modified allergen extracts which have markedly reduced IgE reactivity but identical T cell reactivity compared to untreated extract (Fiebig, 1995, Allergo J. 4 (7): 377-382).
- An even further therapy optimization would be possible with recombinant herO posed allergens.
- Defined cocktails of high-purity, recombinantly produced allergens, if necessary tailored to the individual sensitization patterns of the patients, could replace extracts from natural allergen sources, since these contain, in addition to the various allergens, a larger number of immunogenic but non-allergenic accompanying proteins.
- TH-cell balance in allergy sufferers is immunotherapeutic DNA vaccination. This is a treatment with expressive capable DNA encoding the relevant allergens. Initial experimental evidence for the allergen-specific effect on the immune response could be provided to rodents by injection of allergen-encoding DNA (Hsu et al., 1996, Nature Medicine 2 (5): 540-544).
- the present invention therefore also relates to a DNA molecule described above or below or a corresponding recombinant expression vector as a medicament.
- the corresponding recombinantly produced proteins can be used for the therapy as well as for the in vitro and in vivo diagnosis of pollen allergies.
- a C For the preparation of the recombinant allergen, the cloned nucleic acid is ligated into an expression vector and this construct is expressed in a suitable host organism. After biochemical purification, this recombinant allergen is available for the detection of IgE antibodies in established procedures.
- the present invention therefore furthermore relates to a recombinant expression vector comprising a DNA molecule described above or below, functionally linked to an expression control sequence and a host organism, transformed with said DNA molecule or said expression vector.
- the invention can be used as an essential component in a recombinant allergen- or nucleic acid-containing preparation for specific immunotherapy.
- this can not change in the primary structure
- hypoallergenic (allergoid) form are used for therapy to avoid unwanted side effects.

- Another clone was obtained by PCR with primers # 195 and # 203.
- Primer # 195 was derived from a barley EST sequence, primer # 203 from a wheat EST sequence.
