项目摘要
PROJECT SUMMARY
Maternal immune activation (MIA) refers to the triggering of the maternal immune system during pregnancy by
infections or chronic conditions. This leads to a series of immunologic alterations in the fetus, which can have
an impact on brain development. Large-scale, population-based studies have implicated MIA in a number of
neuropsychiatric disorders, including autism spectrum disorders, bipolar disorder and schizophrenia. Moreover,
studies in rodents have consistently demonstrated that MIA during early phases of pregnancy leads to structural
and functional brain abnormalities and behavioral dysfunction in the offspring. In humans, recent imaging studies
reported similar effects of MIA on child brain structure and behavior. However, these studies were limited by
modest sample sizes and relatively short follow-up periods.
The overall aim of this study is to investigate the impact of maternal immune activation during pregnancy on
adolescent neurodevelopment. We will use the only cohort in the world, Generation R, with both sufficient sample
size and longitudinal follow-up to combine (i) detailed information on infection and inflammation during
pregnancy, with (ii) offspring brain imaging and (iii) behavioral and psychiatric outcomes. In aim 1a we will define
our exposure variable Maternal Immune Activation (MIA). We will use detailed trimester-specific information on
infections and determine the type of infection, as well as severity. We will measure a panel of well-known pro-
inflammatory markers (CRP, IL-1β, IL-6, IL-8, TNF-α) to calculate an inflammatory index of chronic low-grade
inflammation in serum at 13 and 20 weeks of gestation. In aim 1b we will investigate the association between
MIA, fetal growth and gestational age at birth. In aim 2, we will investigate the impact of MIA on offspring brain
structure and connectivity at age 14 years. To test the hypothesis that MIA leads to atypical cortical development,
we will include MRI measures available and ready to use for 3,757 adolescents. These include total brain, white
matter, cortical gray and subcortical volumes. In aim 3 we will determine whether MIA increases the risk for
cognitive deficits, behavioral impairments and psychopathology also at age 14 years.
This project will provide a comprehensive definition of maternal immune activation, including specific aspects of
infection such as type and timing, examine its effects on neurodevelopment, and elucidate putative mechanisms
for these effects in the largest birth cohort to date. Collectively, these outputs will suggest targets for prevention
and aid the efforts towards early identification of high-risk pregnancies.
项目总结
母体免疫激活(MIA)是指在怀孕期间通过以下方式触发母体免疫系统
感染或慢性病。这会导致胎儿的一系列免疫变化,这可能会导致
对大脑发育的影响。大规模的、基于人群的研究表明,MIA与许多
神经精神障碍,包括自闭症谱系障碍、双相情感障碍和精神分裂症。此外,
对啮齿动物的研究一直表明,怀孕早期的MIA会导致结构性
以及后代的大脑功能异常和行为障碍。在人类身上,最近的成像研究
据报道,MIA对儿童大脑结构和行为的影响类似。然而,这些研究受到以下因素的限制
样本量适中,随访期相对较短。
这项研究的总体目标是调查怀孕期间母体免疫激活对
青春期神经发育。我们将使用世界上唯一的队列,R世代,两个足够的样本
规模和纵向随访,以结合(I)关于感染和炎症的详细信息
怀孕,有(Ii)子代脑部成像和(Iii)行为和精神结果。在目标1a中,我们将定义
我们的暴露变量母体免疫激活(MIA)。我们将使用特定于三个月的详细信息
并确定感染的类型和严重程度。我们将测量一组知名的亲王-
炎症标志物(C反应蛋白、IL-1、β、IL-6、IL-8、肿瘤坏死因子-α)计算慢性低级别炎症指标的价值
妊娠13周和20周时血清中出现炎症。在目标1b中,我们将调查两者之间的关联
出生时的胎儿生长发育和胎龄。在目标2中,我们将调查MIA对子代大脑的影响
14岁时的结构和连接性。为了验证MIA导致非典型皮质发育的假设,
我们将包括可供3757名青少年使用的核磁共振检查方法。包括全脑,白色
物质、皮质灰质和皮质下体积。在目标3中,我们将确定MIA是否会增加
认知缺陷、行为障碍和精神病理学也在14岁时出现。
该项目将提供产妇免疫激活的全面定义,包括
感染的类型和时间,检查其对神经发育的影响,并阐明可能的机制
在迄今为止最大的出生队列中发现了这些影响。总体而言,这些产出将提出预防目标。
并帮助努力及早识别高危妊娠。
