概括

通过测量多个IgA抗体,一种新的酶免疫测试可以准确检测乳病. 这种非侵入性测试显示出高灵敏度和特异性,有助于诊断腹腔疾病.

科学领域:

免疫学
胃肠病学
自身免疫性疾病

背景情况:

由于症状多样化和需要进行侵入性活检,诊断乳病 (CD) 是一个挑战.
目前的诊断方法可能无法完全理解CD的免疫反应的复杂性.

研究的目的:

评估一种新的多参数酶免疫试验,用于检测针对八种CD相关抗原的IgA抗体.
在患有和没有腹腔疾病的个体中评估此试验的诊断性能.

主要方法:

一项回顾性研究分析了180名参与者的血清样本 (80名CD患者,50名非乳性小麦敏感患者,50名健康对照患者).
使用AESKUBLOTS®试验同时检测多种IgA抗体.
通过ROC曲线分析和交叉验证来确定诊断的准确性.

主要成果:

该试验显示了高的诊断准确性,抗tTG新型IgA (AUC=0. 93) 和抗tTGIgA (AUC=0. 92) 的表现强.
综合得分为≥4个阳性标记,AUC为0.99,≥6个标记显示100%的特异性.
抗mTGIgA水平在所有CD患者中都升高,不论饮食如何,这表明可能需要监测.

结论:

多参数IgA测试是一种敏感,特异性和非侵入性工具,用于诊断腹腔疾病.
需要进一步的前性研究来验证其在不同人群中的临床效用.

Transcytosis of IgG

Transcytosis of IgG

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...
