自主反应性免疫球蛋白E (IgE) 自体抗体存在于亚托皮炎 (AD) 患者中,特别是那些患有其他2型疾病的患者. 环境因素和并发症会影响阿尔茨海默病的IgE自身抗体的发展.
科学领域:
- 免疫学 免疫学 免疫学
- 皮肤病学 皮肤病学
- 过敏 过敏是一种过敏.
背景情况:
- 对表皮自我的自身反应性免疫球蛋白E (IgE) 抗体在阿托皮性皮炎 (AD) 中被发现.
- 患病率,相关疾病,患者人口统计和AD中IgE自身抗体发展的风险因素尚未得到充分了解.
研究的目的:
- 为了确定IgE自身抗体在血清样本中的患病率,来自具有良好特征的AD患者和对照组.
- 调查IgE自身抗体与阿尔茨海默病,并发性2型疾病以及各种风险因素的关联.
主要方法:
- 分析了672名患者的血清样本 (AD患者和年龄在1.2-88.9岁之间的对照组).
- 艾滋病患者被分为"AD+2型" (患有喘,过敏性鼻炎或食物过敏) 和"仅有艾滋病"的子组.
- 通过使用原发性人类角质细胞的总蛋白质的免疫试验检测出IgE自身抗体.
主要成果:
- 在15%的阿兹海默症患者中检测到IgE自身抗体,在"阿兹海默症+2型"组 (16.4%) 与"仅阿兹海默症" (9.6%) 相比,患病率更高.
- 高水平的IgE自身抗体主要在患有"AD+2型"的患者中发现.
- 年龄较小,总血清IgE水平较高,出生季节 (一月至六月),剖腹产和物多样性与IgE自身抗体的发展有关.
结论:
- 阿尔茨海默病中的IgE自身抗体与阿托皮性并发症和环境因素有关.
- 需要进行进一步的研究,以探索IgE自身抗体作为AD进展和阿托皮征程的预测生物标志物的潜力.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
