Analysis of cross-reactivity between group 1 allergens from mites.
Mite allergen exposure can lead to sensitization in genetically predisposed individuals, and the development of asthma in previously sensitized individuals. The major allergens of mites belong to Dermatophagoides spp. and Blomia tropicalis (Bt). Various allergens of Bt have been cloned and sequenced. Some of them show homology sequence with purified allergens from Dermatophagoides pteronissynus...
متن کاملCross-Reactivity of Peanut Allergens
Peanut seeds are currently widely used as source of human food ingredients in the United States of America and in European countries due to their high quality protein and oil content. This article describes the classification and molecular biology of peanut seed allergens with particular reference to their cross-reactivities. Currently, the IUIS allergen nomenclature subcommittee accepts 12 pea...
متن کاملCross-reactivity of plant and animal allergens.
This review will address cross-reactivity of pollen, fungal, and animal aeroallergens. In the 15 years or so that have transpired since similar reviews on pollen cross-reactivity were published, significant additional information both on cross-allergenicity and on plant systematics has become available (1,2). This review will attempt to incorporate those advances. Cross-reactivity among foods w...
متن کاملCross-reactivity between aeroallergens and food allergens.
In patients with respiratory allergy, cross-reactivity between aeroallergens and foods may induce food allergy, symptoms ranging from oral allergy syndrome to severe anaphylaxis. Clinical entities due to IgE sensitization to cross-reactive aeroallergen and food allergen components are described for many sources of plant origin (pollen-food syndromes and associations, such as birch-apple, cypres...

Methods and results Sequence comparison showed a comparable sequence identity of approximately 70% between the 2EF-hand pollen allergens (Timothy grass: Phl p 7; Alder: Aln g 4; Birch: Bet v 4; Turnip rape: Bra r 1; Lamb ́s quarter: Che a 3; Olive: Ole e 3) and a lower sequence identity of 44% with the 4EF-hand allergen from olive pollen (Ole e 8). While patients ́ IgE showed extensive cross-reac...
