概括

对桃子Gibberellin调节蛋白 (GRPs) 敏感的个体通常会对花粉和其他过敏原表现出共同敏感性. 在这些患者中,PR-10敏感化可能会降低过敏反应的风险.

科学领域:

过敏和免疫学过敏和免疫学
分子生物学分子生物学
临床医学临床医学

背景情况:

吉伯雷林调节蛋白 (GRPs) 是小的糖蛋白,与水果过敏有关.
花粉和食物过敏原之间的交叉反应是过敏性疾病的重要因素.
了解共同敏感化模式对于准确诊断和管理食物过敏至关重要.

研究的目的:

为了评估桃子GRP (Pru p 7) 和树花粉之间的共同敏感性.
评估对其他关键水果过敏分子的共同敏感性:非特异性脂质转移蛋白 (nsLTP, Pru p 3),PR-10蛋白 (Bet v1) 和蛋白质 (Bet v2).
调查共同敏感化模式与过敏反应风险之间的关联.

主要方法:

从四个意大利中心招募了60名对Pru p7敏感的受试者.
测定了Pru p7,Pru p3,Bet v1,Bet v2,树花粉提取物 (Cup s) 和Cup a 1的特定IgE水平.
分析了意大利北部和南部之间敏感度的地理差异.

主要成果:

在Pru p 7敏感个体中,观察到高敏感率的雪松花粉 (Cup s, 90.0%) 和Cup a 1 (83.3%).
对nsLTP (45.8%),PR-10 (40.0%) 和profilin (30.0%) 发现了显著的共同敏感性.
与意大利南部 (6.7%) 相比,意大利北部 (73.3%) 的PR-10共同敏感性明显更为普遍,并且与过敏反应风险降低有关 (OR:0.125).

结论:

在对桃子GRP (Pru p 7) 和树花粉的敏感性之间存在强烈的关联.
在这个患者群体中,对nsLTP,PR-10和profilin的同敏感性是常见的.
显然,PR-10敏感化是防止像过敏症这样的严重过敏反应的保护因素.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
