概括

在TRAF1/C5基因中的单核酸多态性与IgA血管炎 (IgAV) 易感性有关. 在rs3761847的T等位基因可能会对IgAV进行保护,而C和T等位基因与损伤有关.

科学领域:

遗传学是一个遗传学.
免疫学免疫学免疫学
儿科儿科儿科

背景情况:

IgA血管炎 (IgAV) 是一种影响小血管的全身性血管炎.
遗传因素与IgAV的发病有关,但特定的基因关联需要进一步调查.

研究的目的:

检查瘤亡因子受体关联因子1/补充C5 (TRAF1/C5) 基因中rs3761847和rs10818488的单核酸多态 (SNPs) 与儿童患IgAV的风险之间的关联.
探索这些TRAF1/C5基因多态化与IgAV患者脏参与的发生之间的相关性.

主要方法:

一项病例控制研究,涉及100名患有IgAV的儿童和100名健康对照.
使用聚合酶链反应 (PCR) 来提取和放大目标TRAF1/C5基因片段的DNA.
使用PCR测序基于类型的rs3761847和rs10818488位点的基因定型,然后对基因型和等位基因频率进行统计分析.

主要成果:

在IgAV患者和对照组之间观察到rs3761847的基因型和等位基因频率的显著差异 (P < .05).
在rs3761847的TT基因型与IgAV风险降低有关 (OR=0.495),而C等位基因增加了敏感性 (OR=1.627).
在rs3761847的CC基因型和rs10818488的T等位基因与IgAV患者脏参与的风险增加显著相关 (P < .05).

结论:

在TRAF1/C5基因中的单核酸多态 rs3761847与易受IgA血管炎的敏感性有关.
在rs3761847的T等位基因可能起到防止IgAV发育的保护因素作用.
在rs3761847的C等位基因和rs10818488的T等位基因都是IgAV儿童损伤的潜在危险因素.

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...
