项目摘要
DESCRIPTION (provided by applicant): Increasing numbers of pregnant women are prescribed selective serotonin (5-HT) reuptake inhibitor (SSRI) antidepressants to treat depression during pregnancy. SSRI treatment in early pregnancy has recently been associated with increased risk of adverse effects such as autism spectrum disorder (ASD) later in offspring life. Adverse effects are not avoided by foregoing therapy, as untreated depression and the associated maternal stress affect offspring neurological outcomes. Additionally, epidemiological studies cannot clearly separate medication from maternal disease effects on the developing offspring brain. The goal of this project is to dissociate mechanistically the short- and long-term
effects of exposure to maternal stress and to SSRIs on fetal brain development and adult function using a mouse model. The first aim determines the specific parameters of fetal brain exposure to SSRIs and their metabolites, including influence of gestational age, dosage, duration of exposure and identity of the drug. Experiments proposed in this aim take advantage of a newly developed methodology for studying placental drug transport; this unique expertise will permit us to measure bi-directional drug transport between mother and fetus, as well as placental drug accumulation and metabolism at different stages of pregnancy. The second aim investigates the effect of prenatal exposure to maternal stress and commonly used SSRIs (alone and in combination) on fetal brain structure, neurochemistry and serotonergic and thalamocortical neuronal pathway formation. Experiments combine new high-resolution whole fetal brain diffusion magnetic resonance imaging (in collaboration with Dr Irina Burd at Johns Hopkins University), biochemistry and immunohistochemistry to investigate the effects of timing and duration of exposure on structure and neuronal circuit formation in situ. The third aim determines the long-term effects of maternal stress and SSRI exposure at different times of gestation on adult offspring brain function. The proposed experiments use recent advances in highly time-resolved microdialysis (in collaboration with Dr Anne Andrews at UCLA) to determine changes in basal and stimulated extracellular 5-HT levels in ventral hippocampus in awake adult male and female offspring. Relevance to public health: The proposed studies address an urgent need for the investigation of fetal developmental risks that stem from maternal stress/depression and/or its pharmacological treatment during pregnancy, while further defining prenatal sensitive periods that influence complex biological interactions between the mother, placenta and fetal brain. In the long term this research is expected to lead to improved risk assessment, and to help to develop safer therapeutic strategies for pregnant women and their offspring.
描述(由适用提供):规定了孕妇的数量增加,以选择性5-羟色胺(5-HT)再摄取抑制剂(SSRI)抗抑郁药,以治疗怀孕期间的抑郁症。妊娠早期的SSRI治疗最近与后代寿命后期的自闭症谱系障碍(ASD)等不良反应的风险增加有关。由于未经治疗的抑郁症和相关的遗传压力会影响后代神经系统结局,因此不能避免通过上述治疗避免不良反应。此外,流行病学研究无法明确将药物与对发展后代大脑的遗产疾病的影响分开。该项目的目的是机械分离短期和长期
使用小鼠模型暴露于孕产妇应力和SSRI对胎儿脑发育和成人功能的影响。第一个目的决定了胎儿脑暴露于SSRI及其代谢产物的特定参数,包括胎龄,剂量,暴露时间和药物身份的影响。在此目的中提出的实验利用了一种新开发的研究占地药物运输的方法;这种独特的专业知识将使我们能够测量母亲和胎儿之间的双向药物运输,以及在妊娠不同阶段的斑点药物积累和代谢。第二个目的研究了产前暴露于主要压力和常用的SSRI(单独和组合)对胎儿脑结构,神经化学以及血清素能和丘脑皮质神经元途径形成的影响。实验结合了新的高分辨率全胎脑扩散磁共振成像(与约翰·霍普金斯大学的Irina Burd博士合作),生物化学和免疫组织化学,以研究时间和暴露时间对结构和神经元电路形成的影响。第三个目的决定了妊娠不同时间对物物应力和SSRI暴露对成人后代大脑功能的长期影响。提出的实验使用了最新的高度时间分辨微透析(与UCLA的Anne Andrews合作)的进步,以确定在清醒的成年男性和女性后代中腹侧海马中基本和刺激的细胞外5-HT水平的变化。与公共卫生的相关性:拟议的研究迫切需要对胎儿发育风险的投资,这些风险源于孕妇的压力/抑郁症和/或其在怀孕期间的药物治疗,同时进一步定义了产前敏感时期,这会影响母亲,胎盘,胎盘和胎儿大脑之间复杂的生物学相互作用。从长远来看,这项研究有望改善风险评估,并为孕妇及其后代制定更安全的治疗策略。
