概括

孕期非免疫性肝病 (GALD) 研究未能确定由母体抗体准的特定胎儿肝抗原. 需要进一步的研究来确认抗原是否在胎儿发育过程中完全表达.

科学领域:

免疫学免疫学免疫学
肝病学肝病学是一种肝病学.
遗传学遗传学是一个

背景情况:

孕期非免疫性肝病 (GALD) 是一种严重的疾病,由母体抗体攻击胎儿肝细胞引起.
目前的理解表明,未知的胎儿肝抗原是目标,导致肝损伤和潜在的胎儿死亡.
识别这种抗原对于改善诊断和在随后的怀孕中早期使用静脉注射免疫球蛋白进行治疗至关重要.

研究的目的:

为了识别孕期非免疫性肝病 (GALD) 中母亲抗体向的特定胎儿肝抗原.
测试假设,GALD抗原仅在胎儿肝脏中表达,并且是一种抗原.
改善GALD的诊断能力和治疗策略.

主要方法:

胎儿肝脏抗原的免疫沉,然后进行质谱测量.
使用母体抗体对人类胎儿肝脏cDNA表达库的查.
在受影响婴儿的母亲和父亲的外基因组/基因组测序和HLA类型.

主要成果:

在这三种实验方法中,没有一个成功识别了GALD标抗原.
外基因组/基因组测序数据不支持GALD抗原是抗原的假设.
抗原在胎儿生命期间被完全表达的可能性仍然是可信的.

结论:

负责妊娠性非免疫性肝病 (GALD) 的特定抗原仍未确定.
该研究没有发现支持 alloantigen 假设的证据.
假设GALD抗原仅在胎儿生命期间被表达是有利的,需要进一步调查.

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...
