项目摘要
The glutamatergic neurotransmission in the suprachiasmatic nucleus (SCN) plays a central role in the entrainment of the circadian rhythms to environmental light-dark cycles. Although the glutamatergic effect operating via NMDAR is well elucidated, much less is known about a role of AMPAR in circadian entrainment. Here I show that in vivo microinjection of AMPA in the SCN during the early subjective night phase-delays the behavioral rhythm. These data demonstrate that activation of AMPAR is capable of phase-shifting the circadian clock both in vivo and in vitro, and are consistent with the hypothesis that activation of AMPA receptors is a critical step in the transmission of photic information to the SCN.
上核(SCN)中的谷氨酸能神经传递在环境浅黑暗循环中的围栏中起着核心作用。尽管通过NMDAR运行的谷氨酸能效应已经很好地阐明了,但对AMPAR在昼夜节律中的作用知之甚少。在这里,我表明在主观早期的夜间阶段,在SCN中对AMPA的体内显微注射。这些数据表明,AMPAR的激活能够在体内和体外转移昼夜节律,并且与假设AMPA受体的激活是将光学信息传输到SCN的关键步骤。
