Nat Neurosci:薛天团队发现连接昼夜节律与抑郁的神经环路

2020-06-02 MedSci原创 MedSci原创

除了产生视力外,光能调节各种生理功能,包括情绪。虽然人们已知,在白天使用的光疗具有抗抑郁的特性,但也有报导显示,夜间过度的光照射与抑郁症状有关。至今为止,这种光的影响的昼夜差异的神经机制是未知的。

除了产生视力外,光能调节各种生理功能,包括情绪。虽然人们已知,在白天使用的光疗具有抗抑郁的特性,但也有报导显示,夜间过度的光照射与抑郁症状有关。至今为止,这种光的影响的昼夜差异的神经机制是未知的。

通过在小鼠中使用夜间光照(LAN)的范式,中科大薛天团队发现,LAN能够诱导抑郁样行为,而不干扰昼夜节律。这种影响是由一个神经通路介导的,该通路为从视网膜黑素表达的神经节细胞到背侧周叶状核(dpHb),再到横状隔核(NAc)。

重要的是,dpHb是由昼夜节律所控制的,其在夜间比白天更兴奋。这表明,IPRGC→dpHb→NAc通路在夜间优先传导光信号,从而介导LAN诱导的抑郁样行为。

这些研究结果可能与工业世界中普遍存在的夜间照明对心理健康的影响有关。
