1998年,我们的研究小组发现了一个cDNA,它编码两种假定的神经肽的前体,我们称之为hypocretins,因为它们在下丘脑表达,并且与神经肽的分泌素家族相似。在过去的16年里,许多研究已经将下丘脑泌素系统作为稳态功能的整合者,具有作为唤醒稳定剂的关键的非冗余功能。我们最近应用光遗传学方法来询问个体神经元回路在睡眠-觉醒转换中的作用。下丘脑泌素系统和蓝斑(LC)之间的神经元连接似乎是建立适当的自发觉醒动力学的关键。
In 1998, our group discovered a cDNA that encoded the precursor of two putative neuropeptides that we called hypocretins for their hypothalamic expression and their similarity to the secretin family of neuropeptides. In the last 16 years, numerous studies have placed the hypocretin system as an integrator of homeostatic functions with a crucial, non-redundant function as arousal stabilizer. We recently applied optogenetic methods to interrogate the role of individual neuronal circuits in sleep-to-wake transitions. The neuronal connections between the hypocretin system and the locus coeruleus (LC) seem to be crucial in establishing the appropriate dynamic of spontaneous awakenings.
