 DESCRIPTION (provided by applicant): The goal of the proposed training plan is to further develop the applicant's knowledge and research skills in the areas of mood dysregulation, neurocognition, neuro-immunology, advanced statistical methods, and ethics. In line with these goals, the cornerstone of the applicant's training will be the daily activities associated with the proposed study of the inflammatory processes underlying negative mood disturbances and cognitive dysfunction among youth. In addition, this project is carefully aligned with structured training and mentoring experiences to promote the applicant's ultimate career goal to conduct high-quality translational research as an independent investigator on the neurobiological risk factors for affective dysregulation and cognitive dysfunction throughout development that inform the prevention of illness progression and timing of interventions. This training plan includes course work, experience with longitudinal methods and data analyses, regular sponsor meetings, clinical practice, and professional development activities. The proposed research will complement this training plan by providing applied experience with biochemical and neurocognitive methodology, clinical sample recruitment and screening, and data analysis and interpretation. This particular research topic was chosen not only because it fits well with the applicant's career goals and prior experience, but also because depression is highly prevalent among youth and an enormous public health problem, ranking as the leading cause of disability, mortality, and impairment among youth. Further, this project is aligned with the Research Domain Criteria (RDoC) initiative to apply a dimensional approach to study the specific sub- domains of loss within the dimension of negative valence, and cognitive control within the dimension of cognitive systems, that represent core dysfunctions in depression. The proposed project has potential implications for informing the discovery of novel therapeutic targets and the translation of this information into effective treatments specific to youth along a spectrum of severity at elevated risk for a chronic and recurrent course of illness. Immune system response, triggered by stress, is thought to interact with multiple systems (e.g. neurotransmitter metabolism, neuroendocrine function) to predispose towards depression and neurocognitive dysfunction. Therefore, markers of this response may represent a key advance in understanding biomarkers of stress, loss, and cognitive control in mood disorders, as few studies have linked peripheral markers with dimensions of mood and cognition. Further, studies of these markers are strikingly rare among children and adolescents, despite significant methodological obstacles to generalizing findings from adults to youth. Therefore, Aim 1 of the proposed study is to demonstrate differences between youth with any mood disorder (AMD spectrum) and healthy controls in loss and evaluate the association between peripheral inflammatory markers and the loss sub-domain. Aim 2 is to demonstrate differences between AMD spectrum and HC in cognitive control and evaluate the association between peripheral inflammatory markers and the cognitive control sub-domain. Aim 3 is to test the impact of life stress on the association of inflammatory makers with loss and cognitive control. Data will be collected from 30 individuals with a range of negative mood disturbance (AMD spectrum, inclusive of sub-threshold and unspecified conditions) and 30 healthy controls ages 10-17. Mentorship for this project will be provided by experts in the areas of mood dysregulation during development (Dr. Amy West), neurocognition (Dr. Scott Langenecker), neuro-immune function (Drs. Pandey and Goldstein) and data analysis (Dr. Henry). This study will be the first to utilize a dimensional modeling perspective to understanding the associations of inflammation, loss, cognitive control, and stress among youth, as well as one of the first to relate immune system response with measures of neurocognitive function. Thus, the proposed fellowship will be instrumental in propelling the applicant's career and promises to yield results that help specify whether there exist critical periods for neurobiological markers of mood and neurocognitive dysfunction. If the hypotheses are supported it would suggest that targeting biological stress response systems in treatment may disrupt the feed-forward cycle between inflammatory response, mood dysregulation, and neurocognitive dysfunction.

 描述（由申请人提供）：拟议培训计划的目标是进一步发展申请人在情绪失调、神经认知、神经免疫学、高级统计方法和伦理学领域的知识和研究技能。根据这些目标，申请人培训的基石将是与申请相关的日常活动 拟议研究青少年消极情绪障碍和认知功能障碍背后的炎症过程。此外，该项目与结构化培训和指导经验精心结合，以促进申请人的最终职业目标，即作为独立研究者，对整个发育过程中情感失调和认知功能障碍的神经生物学风险因素进行高质量的转化研究，为疾病进展的预防和干预时机提供信息。该培训计划包括课程作业、纵向方法和数据分析经验、定期发起人会议、临床实践和专业发展活动。拟议的研究将通过提供生化和神经认知方法、临床样本招募和筛选以及数据分析和解释方面的应用经验来补充该培训计划。选择这个特定的研究课题不仅是因为它非常适合申请人的职业目标和以往的经验，而且还因为抑郁症在青少年中非常普遍，是一个巨大的公共健康问题，是导致青少年残疾、死亡和损伤的主要原因。此外，该项目与研究领域标准（RDoC）倡议保持一致，应用维度方法来研究负价维度内的损失的特定子领域，以及认知系统维度内的认知控制，这些代表了抑郁症的核心功能障碍。拟议的项目对于发现新的治疗靶点和治疗方法具有潜在的影响。 将这些信息转化为针对青少年的有效治疗方法，针对慢性和复发性疾病风险较高的严重程度。 由压力引发的免疫系统反应被认为与多个系统（例如神经递质代谢、神经内分泌功能）相互作用，容易导致抑郁和神经认知功能障碍。因此，这种反应的标记可能代表了理解情绪障碍中压力、损失和认知控制的生物标记的关键进展，因为很少有研究将外周标记与情绪和认知维度联系起来。此外，尽管将成人的研究结果推广到青少年存在重大的方法学障碍，但在儿童和青少年中对这些标记物的研究却非常罕见。因此，拟议研究的目标 1 是证明患有任何情绪障碍（AMD 谱系）的青少年与健康对照组在损失方面的差异，并评估外周炎症标志物与损失子域之间的关联。目标 2 是证明 AMD 谱系和 HC 在认知控制方面的差异，并评估外周炎症标志物与认知控制子域之间的关联。目标 3 是测试生活压力对炎症产生者与认知控制丧失和认知控制之间关系的影响。数据将从 30 名患有一系列负面情绪障碍（AMD 谱系，包括亚阈值和未指定的情况）的个体和 30 名 10-17 岁的健康对照者中收集。该项目将由发育过程中情绪失调（Amy West 博士）、神经认知（Scott Langenecker 博士）、神经免疫功能（Pandey 和 Goldstein 博士）和数据分析（Henry 博士）领域的专家提供指导。这项研究将是第一个利用维度建模视角来理解青少年炎症、丧失、认知控制和压力之间的关联的研究，也是第一个将免疫系统反应与神经认知功能测量联系起来的研究之一。因此，拟议的奖学金将有助于推动申请人的职业生涯，并有望产生有助于明确情绪和神经认知功能障碍的神经生物学标记是否存在关键时期的结果。如果这些假设得到支持，则表明在治疗中针对生物应激反应系统可能会破坏炎症反应、情绪失调和神经认知功能障碍之间的前馈循环。
