Peanuts are the most common cause of fatal and near-fatal food-induced anaphylaxis. The immune basis for susceptibility to peanut allergy is poorly understood. The current study examined the possibility that patients with peanut allergy, as compared to normals, use different T cell receptor variable beta regions (V beta) in the recognition of peanuts. The results demonstrate that stimulation of T cells from patients with peanut allergy results in the selective expansion of V beta 2+ T cells.
花生是食物诱发的致命和近乎致命过敏反应最常见的诱因。人们对花生过敏易感性的免疫基础了解甚少。当前的研究探讨了花生过敏患者与正常人相比,在识别花生时是否使用不同的T细胞受体可变β区(Vβ)的可能性。结果表明,刺激花生过敏患者的T细胞会导致Vβ2 + T细胞选择性扩增。
