 DESCRIPTION (provided by applicant): The Emory University's "Center for Children's Health, the Environment, Microbiome, and Metabolomics" Center (C- CHEM2) seeks to conduct research on how environmental exposures influence the microbiome of infants and children and the subsequent influence of changes in the microbiome on neurodevelopment. The establishment of a Center focused on the microbiome is significant given that the microbiome is established during the first years of life when development is highly sensitive to the effects of environmental exposures. The investigators' interdisciplinary Center will conduct studies on exposures in an urban environment, the microbiome of pregnant women and their infants, and associated neurocognitive health outcomes. The work of the Center is based on a longitudinal cohort of 800 pregnant African American women who are currently being followed through delivery and designed to examine maternal prenatal stress and its association with the infant microbiome. C-CHEM2 will incorporate a robust assessment of the exposures of the pregnant mother and infant, leveraging substantial resources available from Emory's NIEHS-funded HERCULES Center. The investigators hypothesize that environmental exposure, the microbiome, HPA axis, and immune system together influence neurocognitive and socioemotional development. Type of delivery, genetics, type of feeding, postnatal stress, and maternal-infant interaction are posited as moderators of this intergenerational risk process. Project 1 will focus on the measurement of environmental exposures of the pregnant women and their infants and specifically the association of internal exposures to endocrine-disrupting chemicals in the home environment and their associations with birth outcome. Project 2 will collect infant microbiome, inflammatory marker, and developmental data to examine the association between the prenatal exposures, the infant gut-brain axis, and cognitive/behavioral functioning in the first 18 months of life. Project 3 will use high-resolution metabolomics of the pre- and postnatal samples to test for complex interactions (e.g., exposure x metabolome, microbiome x metabolome, metabolome x HPA axis, immune, neurocognitive and socioemotional measures) that contribute to neurocognitive and socioemotional outcomes. The Community Outreach and Translation Core of C-CHEM2 builds on substantial community engagement already in place in their NIEHS-funded HERCULES Center and provides for bi-directional exchange between African American families in Atlanta and scientists. The investigators' ultimate goal is to assess the influence of the environmental exposures of pregnant women on their microbiome and the subsequent impact of the mother's microbiome on neurodevelopment of the fetus and infant. Achieving this goal would afford a more complete understanding of these effects and consequent ability to translate research strategies to reduce environmental exposures and reduce the prevalence of environmentally-related diseases mitigated by the microbiome.

 描述（由应用程序提供）：埃默里大学的“儿童健康，环境，微生物组和代谢组学中心”中心（C-Chem2）试图​​对环境暴露如何影响婴儿和儿童的微生物组以及微生物组对神经发育的变化的后续影响进行研究。鉴于在生命的头几年中，开发对环境暴露的影响高度敏感，建立了关注微生物组的中心的建立。研究人员的跨学科中心将对城市环境中的暴露，孕妇及其婴儿的微生物组以及相关的神经认知健康结果进行研究。该中心的工作是基于800名怀孕的非洲裔美国妇女的纵向队列，这些妇女目前正在递送，并旨在检查孕产妇的产前压力及其与婴儿微生物组的关联。 C-CHEM2将纳入对怀孕母亲和婴儿暴露的强有力评估，利用Emory的Niehs资助的大力神中心可获得的大量资源。研究人员假设环境暴露，微生物组，HPA轴和免疫系统共同影响神经认知和社会情感发展。提倡作为这种相互作用风险过程的主持人的递送类型，遗传学，进食类型，产后应力和产妇互动的类型。项目1将重点介绍孕妇及其婴儿的环境暴露，尤其是内部暴露于家庭环境中内分泌中断化学物质及其与出生结果的关联的关联。项目2将收集婴儿微生物组，炎症标志物和发育数据，以检查产前暴露，婴儿肠脑轴以及生命前18个月的认知/行为功能之间的关联。项目3将使用产前和产后样本的高分辨率代谢组学测试复杂的相互作用（例如，暴露X代谢组，微生物组X代谢组，代谢组X HPA轴，免疫，神经认知和社会观察测量值），从而有助于神经认知和社会观念型号和社会情感校友。 C-CHEM2的社区宣传和翻译核心建立在其NIEHS资助的大力神中心已经进行的实质性社区参与，并提供了亚特兰大非裔美国人家庭与科学家之间的双向交流。研究人员的最终目标是评估孕妇对微生物组的环境暴露的影响，以及母亲微生物组对胎儿和婴儿神经发育的随后影响。实现这一目标将对这些影响有更完整的理解，并有能力翻译研究策略，以减少环境暴露并降低微生物组减轻环境相关疾病的患病率。
