概括
血清免疫球蛋白A (IgA) 在慢性疹 (CU) 中很重要,独立于Anisakis敏感化. 这项研究强调了IgA.
科学领域:
- 免疫学 免疫学 免疫学
- 过敏学 过敏学
- 寄生虫学的寄生虫学
背景情况:
- 简单虫感染与过敏性疾病和抗体生产模式有关.
- 血清免疫球蛋白A (IgA) 和免疫机制在与阿尼萨基斯相关的疾病中的特定作用仍未得到充分研究.
- 了解这些机制对于诊断和管理对Anisakis的过敏反应至关重要.
研究的目的:
- 为了研究血清IgA和细胞因子概况在胃过敏性病 (GAA) 和Anisakis敏感性慢性病 (CU+) 患者中的作用.
- 为了比较患有和没有阿尼萨基斯敏感和慢性疹症的患者之间的免疫反应.
- 探索特定抗体水平,细胞因子模式和疹表型之间的关系.
主要方法:
- 分析了GAA,CU+,非敏感CU (CU-) 和对照患者的血清样本.
- 细胞因子水平 (IL-2,IL-4,IL-6,IL-10,TNF-α,IFN-γ,IL-17A,TGF-β1) 使用流细胞计测量进行测量.
- 对抗阿尼萨基斯抗原的抗体水平 (IgE,IgG4,IgA) (总数,ES,Anis 1,3,7,13) 通过ELISA进行了量化.
主要成果:
- 在GAA患者中,特定的IgE,IgG4和IgA都升高.
- 与对照组相比,CU+患者的IgA水平和IgA/IgG4比率明显较高,特别是针对特定的Anisakis过敏原.
- 慢性疹患者 (CU+和CU-) 的IL-10,IFN-γ和IL-17A水平较低,与没有疹的对照组相比.
结论:
- 血清IgA在慢性疹中起着重要作用,不论是阿尼萨基斯的敏感化.
- 针对Anisakis过敏原的IgA/IgG4比率可以作为区分过敏反应的生物标志物.

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.

01:15Transcytosis 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...

01:17Gastritis-II: Pathophysiology
327
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...
