项目摘要

DESCRIPTION (provided by applicant): This is a renewal application for a NIDA Independent Scientist Award (K02). The candidate, Amelia J. Eisch, Ph.D., is a tenured Associate Professor in the Department of Psychiatry at UT Southwestern Medical Center. Dr. Eisch is a pioneer in understanding the reciprocal relationship between certain forms of hippocampal plasticity such as adult hippocampal neurogenesis and behaviors relevant to addiction. The first award period of this K02 provided Dr. Eisch with the protected time she needed to accomplish her past goals, which included renewing her NIDA R01 grant on opiates and neurogenesis, securing additional federal funding, advancing her work from correlative to more mechanistic and "causative" studies, and being promoted to Associate Professor and receiving tenure. This K02 renewal is requested in order to continue this protected time and to allow Dr. Eisch to utilize the momentum she has established in understanding the proposed reciprocal role between new neurons in the adult brain and addiction. The receipt of a K02 renewal award would allow her continued protection from administrative burdens, and thus allow Dr. Eisch to advance: (1) research on the relationship between adult-generated neurons and behaviors relevant to addiction; (2) dissection of the cellular, molecular, and genetic control of adult-generated hippocampal neurons; (3) newly developed collaborations on translational profiling, ultrastructural analysis, and circuit-level impact of new neurons; (4) application of new techniques for these collaborations (BAC-TRAP, optogenetics, EM, electrophysiology); (5) data collection for grant applications: the 10-year renewal of her existing R01 on opiates and neurogenesis, a new NIDA R01 relevant to the molecular control of hippocampal neurogenesis, and a new NIDA R01 relevant to behavioral and circuit-level impact of adult-generated neurons. By providing this protected time, Dr. Eisch can work closely with her collaborators and rapidly advance her new ideas, thus benefitting the fields of addiction research and stem cell biology and neuroscience as a whole. The stability and protected time offered by this K02 award would ultimately support at least two new projects exploring the intriguing relationship between adult-generated hippocampal neurons and behaviors relevant to addiction. As these studies hold great potential to improve our understanding of the complex mechanisms by which drugs of abuse affect brain function, they therefore may open new avenues for treatment of addiction and relapse to drug seeking. As these studies also will also shed much-needed light on how adult-generated neurons influence complex behavior - such as drug/context association, extinction from drug-seeking, and behavioral response to stress - they will be important to future efforts to harness neural stem cells for repair of the injured, even addicted, brain and to our understanding of what new neurons can/will do in the adult brain.

描述(申请人提供)：这是NIDA独立科学家奖(K02)的续展申请。候选人阿米莉亚·J·艾施博士是德克萨斯大学西南医学中心精神病学系的终身副教授。Eisch博士是了解某些形式的海马可塑性之间的相互关系的先驱，例如成年海马神经发生和与成瘾相关的行为。K02的第一个获奖期为Eisch博士提供了实现她过去的目标所需的保护时间，其中包括更新她的NIDA R01阿片类药物和神经发生方面的拨款，获得额外的联邦资金，将她的工作从相关研究推进到更机械和更“因果”的研究，并被提升为副教授并获得终身教职。要求更新K02是为了继续这一受保护的时间，并允许Eisch博士利用她在理解成人大脑中新神经元与成瘾之间拟议的相互作用方面建立的势头。K02更新奖的获得将使她能够继续保护她免受行政负担的影响，从而使Eisch博士能够在以下方面取得进展：(1)成人产生的神经元和与成瘾相关的行为之间的关系的研究；(2)成人产生的海马神经元的细胞、分子和基因控制的解剖；(3)在翻译图谱、超微结构分析和新神经元的电路水平影响方面新开发的合作；(4)这些合作的新技术的应用(BAC-Trap、光遗传学、EM、电生理学)；(5)拨款申请的数据收集：HER现有的关于阿片类药物和神经发生的R01的10年续期，与海马神经发生的分子控制有关的新的NIDA R01，以及与成人产生的神经元的行为和电路水平的影响有关的新的NIDA R01。通过提供这段受保护的时间，艾施博士可以与她的合作者密切合作，迅速推进她的新想法，从而使成瘾研究、干细胞生物学和整个神经科学领域受益。K02奖提供的稳定性和保护时间最终将支持至少两个新项目，探索成人产生的海马神经元和与成瘾相关的行为之间的有趣关系。由于这些研究具有巨大的潜力，可以提高我们对滥用药物影响大脑功能的复杂机制的理解，因此它们可能会为治疗成瘾和复吸药物开辟新的途径。由于这些研究还将揭示成人产生的神经元如何影响复杂的行为--如药物/背景联系、药物寻求的灭绝和对压力的行为反应--这些研究将对未来利用神经干细胞修复受伤的、甚至成瘾的大脑的努力以及我们理解新的神经元可以/将在成人大脑中起什么作用非常重要。
