NATURE:T细胞是如何介导流产和妊娠期糖尿病的?

2020-12-26 haibei MedSci原创

胸腺Rank的缺失也会导致Treg细胞在内脏脂肪组织中的积累受损,并与脂肪细胞增大、组织炎症、母体葡萄糖不耐受性增强、胎儿大头症和葡萄糖平衡的长期改变有关,这些都是妊娠期糖尿病的关键标志。

在怀孕期间,性激素有助于帮助孕妈妈的生理适应,并保障胎儿发育。在女性性激素的控制下,NF-κB配体的受体激活剂(RANK)及其配体RANKL可以调节骨重塑和哺乳期乳腺的发育。在胸腺中,RANK信号调节AIRE-和CD80表达的髓质胸腺上皮细胞(mTECs)的成熟,进一步参与自然胸腺Treg细胞的发育。因此,研究人员推测,在怀孕期间RANK可以介导重要的胸腺适应过程。

最近,研究人员在Nature杂志发文,报导破骨细胞分化受体RANK耦合女性性激素,在怀孕期间的胸腺重新分布。胸腺上皮细胞中Rank(也称为Tnfrsf11a)的遗传性缺失导致胸腺内卷受损和自然调节性T(Treg)细胞在怀孕雌性小鼠中钝化扩张。
性激素,尤其是孕激素,通过RANK驱动胸腺Treg细胞的发育,该过程依赖于AIRE+髓质胸腺上皮细胞。

鼠胸腺上皮细胞中Rank的耗竭可以导致胎盘中天然Treg细胞积累减少,流产数量增加。胸腺Rank的缺失也会导致Treg细胞在内脏脂肪组织中的积累受损,并与脂肪细胞增大、组织炎症、母体葡萄糖不耐受性增强、胎儿大头症和葡萄糖平衡的长期改变有关,这些都是妊娠期糖尿病的关键标志。
Treg细胞的移植可以治疗流产、母体葡萄糖不耐受和巨婴的发生。
在人类妊娠中,研究人员也发现妊娠糖尿病与胎盘中Treg细胞数量减少有关。
因此,该研究结果表明,RANK在妊娠期间促进了激素介导的胸腺Treg细胞的发育,并将母体Treg细胞的功能作用扩展到妊娠糖尿病的发生和葡萄糖稳态的跨代代谢重配。

**医学期刊BMJ:42万队列研究,年龄越大,越容易流产;流产次数越多,再次怀孕,流产的风险就越大

流产是妊娠的常见结果,大多数研究表明,妊娠20周后确认的妊娠损失率为12%至15%,量化流产的全部负担具有挑战性,另外,公认损失的总比率对早期妇女识别怀孕的方式很敏感。根据国家登记处或基于人群的队列研究,瑞典,芬兰和丹麦报告的流产风险在12.9%至13.5%之间。虽然大多数流产的原因尚不清楚,但它们可能是由于父母年龄,遗传,激素,免疫和环境因素之间复杂的相互作用造成的。遗传因素,包括父母染色体重排

不同类型流产的超声表现

medRxiv:暨南大学周庆华研究员参与的队列研究,揭示全外显子组测序在妊娠流产中的临床实用性

众所周知,基因异常会导致妊娠丢失。最近的WES研究在84例有超声异常的胎儿死亡病例中分别检测到阳性、可能和候选变异的20%、45%和9%,在19例错失流产的POC病例中,有15例存在序列变异。在一个由

Medicine:流产会增加乳腺癌的发病风险?!NO!
