迄今为止,在啮齿动物中涉及加压素(Avp)调节社会行为的大部分工作集中在其通过Avp 1a受体(Avpr1a)的作用。然而,越来越多的证据表明,Avp 1b受体(Avpr1b)在Avp对社会行为的调节中也起着重要作用。Avpr1b在垂体前叶促皮质激素细胞上大量表达,在那里它作为内分泌应激反应的重要调节剂。在大脑中,Avpr1b在海马体的CA2区很突出,但也可以在下丘脑的脑室旁核和嗅球等区域发现。对Avpr1b进行基因敲除或药理学操作的研究指出了中枢Avpr1b在调节社会行为中的重要性。然而,在我们对大脑中发生这种情况的位置以及Avp通过Avpr1b起作用的中枢作用如何以及是否与应力轴相互作用的理解方面仍然存在知识差距。在这篇综述中,我们重点关注遗传和药理学研究,这些研究表明Avpr1b参与了社会行为的神经调节,包括攻击性行为的社会形式、社会记忆和社会动机。
To date, much of the work in rodents implicating vasopressin (Avp) in the regulation of social behavior has focused on its action via the Avp 1a receptor (Avpr1a). However, there is mounting evidence that the Avp 1b receptor (Avpr1b) also plays a significant role in Avp's modulation of social behavior. The Avpr1b is heavily expressed on the anterior pituitary cortiocotrophs where it acts as an important modulator of the endocrine stress response. In the brain, the Avpr1b is prominent in the CA2 region of the hippocampus, but can also be found in areas such as the paraventicular nucleus of the hypothalamus and the olfactory bulb. Studies that have employed genetic knockouts or pharmacological manipulation of the Avpr1b point to the importance of central Avpr1b in the modulation of social behavior. However, there continues to be a knowledge gap in our understanding of where in the brain this is occurring, as well as how and if the central actions of Avp acting via the Avpr1b interact with the stress axis. In this review we focus on the genetic and pharmacological studies that have implicated the Avpr1b in the neural regulation of social behaviors, including social forms of aggressive behavior, social memory, and social motivation.
