  • Publication number: 20080261215
    Abstract: The present invention discloses a method for evaluating the allergen sensitivity of an individual and/or the clinical efficacy of an allergen immunotherapy comprising the steps: providing at least two samples selected from the group consisting of blood or fractions thereof, connective tissue, nasal, bronchial, skin or gut biopsy material from an individual subjected or intended to be subjected to an immunotherapy with at least one pure allergen or derivative thereof, wherein the samples contain cells capable of releasing mediators in response to said allergen, contacting said sample with said allergen or derivative thereof, and determining the amounts of mediators released from said sample and evaluating the allergen sensitivity of the individual prior to therapy and/or the clinical efficacy of the immunotherapy by comparing said amounts.

  • Patent number: 7148019
    Abstract: A recombinant DNA molecule comprising a nucleotide sequence (I) which codes for a polypeptide displaying the antigenicity of one, two or more of the Phl p I epitope clones (28, 34, 41, 42, 43, 45, 50, 52, 64, 80, 85, 86, 95, 97, 98, 103, 108, 109, 113, 114), with the amino acid sequences defined in SEQ ID NOS: 5, 7, 9 and 12–28, and preferably being derived from grasses or monocotyledonic plants, or a nucleotide sequence (II) which hybridizes with such a nucleotide sequence (I) under conditions of high, stringency. Polypeptides displaying the antigenicity of one, two or more of the Phl p I epitope clones (28, 34, 41, 42, 43, 50, 52, 64, 80, 85, 86, 95, 97, 98, 103, 108, 109, 113, 114).
