摘要:

季节性繁殖是动物适应自然环境变化的一种策略,通过在合适的时间繁殖来保证后代的存活和生长,GnRH神经元对雌激素负反馈响应的显著变化是调节季节性繁殖的主要原因。近年来,科学家对绵羊季节性繁殖的神经和神经内分泌调控进行了大量研究,主要集中在下丘脑褪黑激素及相关神经元的活动。本文综述了绵羊季节性繁殖的传入信号和神经通路,简要比较了绵羊和仓鼠季节性繁殖的相关研究,为绵羊季节性繁殖神经机制研究提供参考。

Abstract:

Seasonal reproduction is a common adaptive strategy that allows for breeding at times when it is most advantageous for survival and growth of offspring, a major reason for seasonal reproduction is a striking change in the responsiveness of gonadotropin-releasing hormone (GnRH) neurons to the negative feedback effects of estradiol. In recent years, the neural and neuroendocrine circuitry responsible for sheep seasonal reproduction has been primarily studied, which concerned with the melatonin action and changes of the relevant neuron activities in hypothalamus. In this review, we first described the afferent signals, neural circuitry for seasonal reproductive transitions in sheep, and then compared these mechanisms with those discovered from studies in hamsters. These results can provide reference for the study of neural mechanisms controlling seasonal reproduction in sheep.
