项目总结/摘要
面对消极的生活经历,保持情绪稳定对健康老龄化至关重要。适应不良
对负性情感刺激的反应(“NAFecS”)与精神障碍有关,包括主要的
抑郁症(MDD)。事实上,有共同的大脑区域参与对NAFecS和MDD的反应。
病理生理学,包括:下丘脑(HYPO)、杏仁核(AMYG)、海马(HIPP)、前扣带回
大脑皮层(ACC),腹内侧和眶前额叶皮层(vmPFC,OFC),这些区域是高度性别化的区域。
二形的这一回路的活动在生理上与皮质醇反应、副交感神经系统的丧失有关。
心脏张力和免疫反应,包括TNF-α、IL-1β、IL-6,所有这些都因性别而异。我们将在这里测试

英文摘要
Project Summary/Abstract
Maintaining emotional stability in the face of negative life experiences is critical for healthy aging. Maladaptive
responses to negative affective stimuli (“NAffecS”) are implicated in psychiatric disorders, including major
depressive disorder (MDD). In fact, there are shared brain regions involved in responses to NAffecS and MDD
pathophysiology, including: hypothalamus (HYPO), amygdala (AMYG), hippocampus (HIPP), anterior cingulate
cortex (ACC), and ventromedial and orbital prefrontal cortices (vmPFC, OFC), areas that are highly sexually
dimorphic. Activity in this circuitry is physiologically associated with cortisol response, loss of parasympathetic
cardiac tone, and immune responses, including TNF-α, IL-1β, IL-6, all of which differ by sex. We will test here
that immune pathway abnormalities, beginning in fetal development, are associated with sex-dependent
impacts on HYPO, HIPP, AMYG and PFC, resulting in maladaptive negative emotion processing and
MDD/depressed mood symptomatology in early midlife, the latter of which will accelerate aging of this circuitry
and negative emotion dysregulation in later midlife. We are uniquely poised to examine this for the first time in
humans using data from our 55-year prospective prenatal cohort followed since 2nd/3rd trimesters of gestation
and assessed at ages 44-50 in a previous NIMH study. Over 4 years, we will re-recruit 160 of these offspring
who, 11 years later, will be ages 55-61, and relate maternal prenatal immune activity (TNF-α, IL-1β, IL-6, IL-10)
to sex differences in midlife NAffec circuitry decline and negative emotion processing dysregulation and the
impact of MDD/severe mood symptomatology in early midlife. We will use the same multimodal imaging
approach as previously (structural, functional imaging (sMRI/fMRI)) coupled with hormones, autonomic and
immune physiology, and emotion regulation measures. Novel transcriptomic analyses in the offspring's
peripheral blood mononuclear cells (PBMCs; measuring innate immune gene expression) will be related to
adult midlife outcomes. Our lifespan perspective is an innovative approach to identify potential
immunotherapeutic targets for maintaining healthy emotion processing that are sex-dependent and can be
applied prior to functional decline. This will contribute to RDoC Negative Affect and Arousal phenotypes,
physiology and genotypes, and impact of mood and sex.
