IgE cross-reactivity between the major peanut allergen Ara h 2 and the non-homologous allergens Ara h 1 and Ara h 3
BACKGROUND Ara h 1, a vicilin; Ara h 2, a 2S albumin; and Ara h 3, a legumin, are major peanut allergens. Ara h 2 is an important predictor of clinical reactivity to peanut, but cosensitization to all 3 allergens is correlated with the severity of patients' symptoms. OBJECTIVE We investigated whether cosensitization to these 3 allergens is caused by IgE cross-reactivity, despite the fact that...
متن کاملAra h 2 and Ara h 6 have similar allergenic activity and are substantially redundant.
BACKGROUND The moderately homologous (approx. 60%) proteins Ara h 2 and Ara h 6 are the most potent peanut allergens. This study was designed to define the relative individual contributions of Ara h 2 and Ara h 6 to the overall allergenic activity of a crude peanut extract (CPE). METHODS Ara h 2 and Ara h 6 were removed from CPE by gel filtration chromatography. Ara h 2.01, Ara h 2.02 and Ara...
متن کاملEffect of heating and glycation on the allergenicity of Ara h 2/6
Results Heating Ara h 2/6 at 110°C resulted in extensive denaturation whilst Ara h 2/6 extracted from roasted peanut retained its native conformation. Allergen stimulation of PBMC from peanut allergic patients induced proliferation of mainly CD4+ T-cells and induction of Th2 cytokine secretion which was unaffected by thermal processing. IgE reactivity and functionality of Ara h 2/6 was decrease...

Ara h 6 complements Ara h 2 as an important marker for IgE reactivity to peanut
The similarities of two major peanut allergens, Ara h 2 and Ara h 6, in molecular size, amino acid sequence, and structure have made it difficult to obtain natural Ara h 6 free of Ara h 2. The objectives of this study were to purify natural Ara h 6 that is essentially free of Ara h 2 and to compare its IgE reactivity and potency in histamine release assays to Ara h 2. Sodium dodecyl sulfate-pol...
