中文摘要
对可卡因等精神兴奋剂的成瘾是一个严重的公共卫生问题
财务和社会成本。 尽管如此,精神兴奋剂使用障碍仍然是一种顽固性疾病,没有任何影响
目前 FDA 批准了用于治疗的药物。 在精神病学研究的许多领域中,
大脑和免疫系统已被广泛研究作为确定病理生理学并发现
新的治疗方法。 虽然众所周知,可卡因可以改变先天性和适应性的功能
免疫系统,这些免疫变化与适应不良的吸毒和寻求行为之间的联系
仍然处于最低限度的探索之中。 在一系列初步实验中,我们研究了实验者或自我如何
施用可卡因改变了 32 种细胞因子的血清特征。 其中,我们发现粒细胞集落
可卡因会增加刺激因子 (G-CSF),并且血清水平与可卡因呈线性相关
对可卡因的行为反应。 在行为上,注射 G-CSF 会改变可卡因的剂量反应曲线
地点偏好,促进可卡因灭绝并减少可卡因寻求的恢复。 综合起来,这些
初步研究表明,G-CSF 是可卡因诱导的行为可塑性的有效调节剂,并且
可能是延长可卡因使用障碍戒断时间的潜在治疗目标。 在指导下
博士的。 Eric Nestler 和 Yasmin Hurd 我将寻求进一步阐明 G-CSF 在成瘾中的作用,同时获得
额外的培训让我能够过渡到独立。 在本提案的目标 1 中,我将询问

G-CSF 行为效应的基础,将为我提供自我管理和治疗方面的重要培训

英文摘要
Addiction to psychostimulants such as cocaine represents a major public health issue exacting tremendous
financial and social costs. Despite this, psychostimulant use disorder remains a recalcitrant condition with no
currently FDA-approved medications for its treatment. In many fields of psychiatric research, the link between
the brain and the immune system has been heavily studied as a way to determine pathophysiology and to find
new methods of treatment. While it is known that cocaine can alter the function of both the innate and adaptive
immune systems, the link between these immune changes and maladaptive drug taking and seeking behaviors
remains minimally explored. In a series of initial experiments, we examined how experimenter or self-
administered cocaine altered the serum profile of 32 cytokines. Of these, we found that granulocyte-colony
stimulating factor (G-CSF) was increased by cocaine, and the serum levels showed linear correlation with
behavioral response to cocaine. Behaviorally, injections of G-CSF alter the dose-response curve for cocaine
place preference, and facilitate extinction and reduce reinstatement of cocaine seeking. Taken together, these
preliminary studies demonstrate that G-CSF is a potent modulator of cocaine-induced behavioral plasticity, and
may be a potential therapeutic target for prolonging abstinence in cocaine use disorder. Under the mentorship
of Drs. Eric Nestler and Yasmin Hurd I will seek to further clarify the role of G-CSF in addiction while gaining
additional training to allow me to transition to independence. In Aim 1 of this proposal I will interrogate the
effects of G-CSF in the nucleus accumbens (NAc) in a cell-type specific manner by using viral vectors to knock
down the G-CSF receptor in populations of D1 and D2 positive medium spiny neurons prior to cocaine self-
administration, extinction and reinstatement. These experiments will provide insight into the microcircuitry
underlying the behavioral effect of G-CSF, and will provide me crucial training in self-administration and
targeted manipulation of gene expression. In Aim 2, I will seek to identify G-CSF responsive genes in NAc that
account for its behavioral effect. I will perform mRNA sequencing of the NAc from animals self-administering
cocaine, followed by differential expression and pathway analysis. The behavioral effect of highly regulated
genes and pathways will be interrogated by viral gene manipulation prior to cocaine self-administration,
extinction and reinstatement. These experiments will provide me with crucial mentoring in creation, analysis
and utilization of large sequencing datasets, while also providing detailed information as to how G-CSF affects
cocaine-related behavioral plasticity. In summary, the research proposed in this award will elucidate the neural
and molecular mechanisms of a translationally-relevant treatment target, while providing me with sufficient
mentorship to transition into an independent investigator.
