项目摘要
PROJECT SUMMARY
Social attachments form the basis of human relationships at every level of social organization, from
relationships between parents and children, romantic partners, to peers and group affiliation. Disruptions in
attachment occur across the spectrum of mental illness, and severe neuropsychiatric disorders often manifest
with a dramatic collapse of social attachment and cognition. Despite this critical role of social attachment, little
is known regarding the neural and genetic mechanisms underlying attachment. Mice and other genetic model
organisms do not exhibit enduring social attachments, precluding genetic analysis of these behaviors.
Prairie voles are small rodents that display social monogamy, or pair bonds, between mates. Pair bond
formation results in dramatic changes to many other innate social behaviors. Thus, prairie voles engage in a
rich repertoire of social behaviors that strikingly mirror attachment in humans. Pioneering work identified the
peptide hormones vasopressin (Avp) and oxytocin (Oxt), as critical mediators of pair bonding in voles and
social cognition and behaviors in humans. These findings suggest that the genetics and neural control of social
attachment may be conserved, and indeed, have inspired clinical trials seeking to use these hormones to
ameliorate disruptions in social cognition due to neuropsychiatric conditions. Nevertheless, how these
pathways and other genes function to control specific aspects of complex social behaviors remains unknown.
Until now, we have been unable to understand how OxtR and V1aR function to control patterns of
neural activity in response to partners or strangers. We have generated prairie voles bearing mutations in OxtR
and V1aR that completely eliminate the function of these receptors, and developed approaches for optical
recording of neural activity in freely moving animals during behavior and profiling of gene expression in prairie
voles. Using this powerful system, we can now test the hypothesis that OxtR and V1aR control distinct aspects
of 1) pair bonding and adult social attachment behaviors, 2) partner- or stranger-specific patterns of neural
activity in specific regions of the vole brain during social interactions, and 3) changes in gene expression
underlying social attachment in these neural populations. Our preliminary work suggests that OxtR signaling is
not required genetically for pair bonding in prairie voles, and, thus, that a more refined understanding of the
neural and molecular pathways underlying social attachment may provide new insights into the pathways that
mediate the formation of such long term social memory and affiliation. These studies will elucidate the
mechanisms by which OxtR and V1aR facilitate attachment and, eventually, inform new therapeutic
approaches across the spectrum of mental illness.
项目概要
社会依恋构成了社会组织各个层面的人际关系的基础,从
父母与孩子、浪漫伴侣、同龄人和团体之间的关系。中断
依恋发生在各种精神疾病中,严重的神经精神疾病常常表现出来
社会依恋和认知的急剧崩溃。尽管社会依恋发挥着至关重要的作用,但很少有
关于依恋背后的神经和遗传机制是已知的。小鼠和其他遗传模型
生物体不表现出持久的社会依恋,排除了对这些行为的遗传分析。
草原田鼠是小型啮齿动物,在配偶之间表现出社会一夫一妻制或配对关系。配对债券
形成会导致许多其他先天社会行为的巨大变化。因此,草原田鼠从事
丰富的社会行为惊人地反映了人类的依恋。开创性的工作确定了
肽类激素加压素 (Avp) 和催产素 (Oxt),作为田鼠配对结合的关键介质
人类的社会认知和行为。这些发现表明,社会的遗传学和神经控制
依恋可能是保守的,事实上,这激发了临床试验,试图利用这些激素来
改善神经精神疾病引起的社会认知障碍。尽管如此,这些如何
控制复杂社会行为特定方面的途径和其他基因功能仍然未知。
到目前为止,我们还无法理解 OxtR 和 V1aR 如何发挥作用来控制
对伴侣或陌生人做出反应的神经活动。我们已经培育出带有 OxtR 突变的草原田鼠
和 V1aR 完全消除了这些受体的功能,并开发了光学方法
记录草原中自由活动动物的行为过程中的神经活动以及基因表达谱
田鼠。使用这个强大的系统,我们现在可以测试 OxtR 和 V1aR 控制不同方面的假设
1) 配对关系和成人社会依恋行为,2) 伴侣或陌生人特定的神经模式
社交互动期间田鼠大脑特定区域的活动,以及 3) 基因表达的变化
这些神经群体中潜在的社会依恋。我们的初步工作表明 OxtR 信号传导是
草原田鼠的配对不需要基因,因此,对
社会依恋背后的神经和分子途径可能会为社会依恋的途径提供新的见解
调解这种长期社会记忆和归属感的形成。这些研究将阐明
OxtR 和 V1aR 促进附着并最终为新的治疗提供信息的机制
治疗各种精神疾病的方法。
