IgE合成的位置一直是一个长期存在的争议,以前的证据有利于在过敏原进入区域的粘膜或淋巴组织。粘膜组织中IgE合成的证据一直是间接的。我们已经开发了一种新的外植体培养系统,使用ELISA和放射性氨基酸掺入,以衡量从头IgE蛋白质合成的花粉热患者的鼻粘膜。令人惊讶的是,在来自草花粉敏感患者的外植体中,IgE合成在季节之间继续,并且与血清IgE相比,该IgE的更高比例是过敏原特异性的。持续的IgE合成可确保粘膜中的速发型超敏反应的表达,并促进局部淋巴组织中对变应原激发的过敏反应的快速放大。我们的工作首次明确表明,局部粘膜是一个正在进行的IgE合成的网站。
The location of IgE synthesis has been a longstanding controversy, with previous evidence favoring either the mucosa or lymphoid tissue in the region of allergen entry. The evidence for IgE synthesis in mucosal tissues has always been circumstantial. We have developed a novel explant culture system, using ELISA and radioactive amino acid incorporation, to measure de novo IgE protein synthesis in the nasal mucosa of hay fever patients. Surprisingly, IgE synthesis continues between seasons in the explants from grass pollen‐sensitive patients and a higher proportion of this IgE compared to serum IgE is allergen specific. Persistent IgE synthesis may ensure the expression of immediate hypersensitivity in the mucosa and promote rapid amplification of the allergic response in the local lymphoid tissue on allergen provocation. Our work demonstrates definitively for the first time that the local mucosa is a site of ongoing IgE synthesis.
