Abstract

Stressful stimuli abound in modern society and have shaped evolution through altering reproductive development, behavior, and physiology. The recent identification of kisspeptin as an important component of the hypothalamic regulatory circuits involved in reproductive homeostasis sparked a great deal of research interest that subsequently implicated kisspeptin signaling in the relay of metabolic, environmental, and physiological cues to the hypothalamo-pituitary-gonadal axis. However, although it is widely recognized that exposure to stress profoundly impacts on reproductive function, the roles of kisspeptin within the complex mechanisms underlying stress regulation of reproduction remain poorly understood. We and others have recently demonstrated that a variety of experimental stress paradigms downregulate the expression of kisspeptin ligand and receptor within the reproductive brain. Coincidently, these stressors also inhibit gonadotropin secretion and delay pubertal onset-processes that rely on kisspeptin signaling. However, a modest literature is inconsistent with an exclusively suppressive influence of stress on the reproductive axis and suggests that complicated neural interactions and signaling mechanisms translate the stress response into reproductive perturbations. The purpose of this chapter is to review the evidence for a novel role of kisspeptin signaling in the modulation of reproductive function by stress and to broaden the understanding of this timely phenomenon.

摘要

现代社会充满了压力刺激,通过改变生殖发育、行为和生理学,塑造了进化。最近发现,促亲吻素作为参与生殖稳态的下丘脑调节回路的重要组成部分,引发了大量研究兴趣,随后表明促亲吻素信号在将代谢、环境和生理线索传递到下丘脑-垂体-性腺轴方面发挥作用。然而,尽管人们普遍认识到压力会深刻影响生殖功能,但促亲吻素在压力调节生殖的复杂机制中的作用仍知之甚少。我们和其他人最近表明,各种实验性应激范式下调了生殖脑中促亲吻素配体和受体的表达。巧合的是,这些应激源也抑制了促性腺激素的分泌并延迟了青春期的开始,这一过程依赖于促亲吻素信号。然而,一个适度的文献与应激对生殖轴的唯一抑制影响不一致,并表明复杂的神经相互作用和信号机制将应激反应转化为生殖紊乱。本章的目的是综述促亲吻素信号在应激调节生殖功能中的新作用的证据,并拓宽对这一时事现象的理解。
