项目摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
The experience of early life stress puts individuals at greater risk for psychopathology later in life. Multiple neural pathways contribute to this risk, but the serotonin transporter (5-HTT) is among the foremost of these. The target of the most effective antidepressants, neural 5-HTT expression is lower in depressed patients and in victims of early life stress. Identifying the mechanism(s) of plasticity in 5-HTT gene function or of its transcription factors following early stress may therefore inform intervention strategies to improve mental health following trauma. The PI will investigate whether a well-characterized experimental early life stressor leads to dysregulation of 5-HTT and one of its major transcriptional enhancers(glucocorticoid receptor, NR3C1 or GR) in infant rhesus macaques, and whether this dysregulation is epigenetically mediated.

早期生活压力的经历使个体在以后的生活中面临更大的精神病理学风险。多种神经通路导致这种风险,但5-羟色胺转运体(5-HTT)是其中最重要的。最有效的抗抑郁药的目标,神经5-HTT表达在抑郁症患者和早期生活压力的受害者中较低。因此,确定5-HTT基因功能或其转录因子在早期应激后的可塑性机制可能为改善创伤后心理健康的干预策略提供信息。PI将调查一种特征良好的实验性早期生活压力源是否会导致幼年恒河猴中5-HTT及其主要转录增强子之一(糖皮质激素受体NR 3C 1或GR)的失调,以及这种失调是否是表观遗传学介导的。
