概括
确定正常的血清总免疫球蛋白E (IgE) 水平是一项挑战. 个性化的IgE生长图表对于识别无形个体和理解IgE至关重要.
科学领域:
- 免疫学 免疫学 免疫学
- 过敏学 过敏学
背景情况:
- 与其他免疫球蛋白 (Ig) 类不同,关于正常血清总IgE水平没有确立的共识.
- 纵向出生队列研究已经为无虫,非形儿童生成了IgE生长图表,使个人水平的正常范围定义成为可能.
- 这种方法突出了"低IgE生产者",尽管IgE水平相对于一般人群相对看似正常,但他们可能会发展出亚托皮.
研究的目的:
- 强调个体IgE生长轨迹对基于人口的正常范围的重要性.
- 通过考虑IgE特定活性,重新定义"低IgE生产者"的亚托皮诊断标准.
- 探索低IgE生产与其他健康状况 (包括恶性瘤) 的关联.
主要方法:
- 来自出生队伍的纵向IgE数据的分析.
- 个人IgE百分位轨迹与基于人口的正常范围的比较.
- 在诊断过敏时评估IgE特异性活性 (过敏原特异性IgE/总IgE比率).
主要成果:
- "低IgE生产者"可能会发展出亚托皮,他们的IgE水平与人口数据相比似乎正常,但与他们自己的百分位轨迹相比却很高.
- 特定IgE活性是一个比绝对特定IgE水平更可靠的指标,用于确认"低IgE生产者"中的过敏原因果关系.
- 低IgE水平与常见的可变免疫缺陷,肺部疾病和恶性瘤风险增加有关.
结论:
- 个性化IgE生长图表对于准确的瘤诊断至关重要,特别是在"低IgE生产者"中.

Hypersensitivities
812
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Antibody Structure

Overview
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.

Allergic Drug Reactions
901
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Antigens Involved in Adaptive Immunity
568
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Transcytosis of IgG
2.8K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
