概括

系统性红斑狼 (SLE) 怀孕不能在单细胞中发展免疫耐受性,与健康和类风湿关节炎 (RA) 怀孕不同. 异常的微RNA (miRNA) 调节有助于SLE持续性炎症,提供潜在的生物标志物.

科学领域:

免疫学免疫学免疫学
基因组学就是基因组学.
生殖医学生殖医学

背景情况:

怀孕通常会诱导免疫耐受性,降低自身免疫活性.
系统性红斑狼 (SLE) 妊娠带有爆发和并发症的风险.
风湿性关节炎 (RA) 通常在怀孕期间得到改善,与SLE相比.

研究的目的:

在健康,RA和SLE怀孕期间调查单细胞的转录和微RNA (miRNA) 变化.
了解SLE和RA怀孕之间的免疫差异.
为了确定SLE怀孕的炎症背后的分子机制.

主要方法:

从健康,RA和SLE怀孕中长度表征单细胞 (怀孕前到产后3个月).
对CD14+单细胞的RNA测序和miRNA测序.
不同表达分析,路径丰富和miRNA-mRNA网络推断.

主要成果:

健康和RA怀孕表明转向抗炎单细胞表型.
在SLE怀孕中,在整个妊娠期间都保持了亲炎性单细胞表型.
在SLE单细胞中,与炎症途径相关的特定miRNAs (miR-106a-5p,miR-148b-5p) 的下调.

结论:

在SLE怀孕中,表现出无法实现单细胞免疫耐受性的失败.
异常的miRNA调节是SLE怀孕中持续炎症的关键驱动因素.
已识别的转录组和miRNA生物标志物可能有助于风险分层和治疗策略.

关键词:

A Novel Use of Three-dimensional High-frequency Ultrasonography for Early Pregnancy Characterization in the Mouse

Mice are widely used to study gestational biology. However, pregnancy termination is required for such studies which precludes longitudinal investigations and necessitates the use of large numbers of animals. Therefore, we describe a non-invasive technique of high-frequency ultrasonography for early detection and monitoring of post-implantation events in the pregnant mouse.
