重要的历史事件被铭记。虽然已知情绪体验的记忆是由应激激素糖皮质激素介导和调节的,但对潜在的分子机制知之甚少。在此,我们发现,在大鼠长期抑制性回避记忆形成过程中,海马糖皮质激素受体与CaMKIIα、TrkB、ERK、Akt、PLCγ和CREB的激活以及Arc和突触GluA 1的显著诱导相耦合。这些变化中的大多数是由糖皮质激素受体的非基因组效应引发的,也是脑源性神经营养因子(BDNF)激活的下游。脑源性神经营养因子的海马给药,而不是其他神经营养因子,选择性地挽救了健忘症和糖皮质激素受体抑制产生的分子损伤。因此,糖皮质激素受体通过募集CaMKIIα-BDNF-CREB依赖性神经可塑性通路介导长期记忆的形成。
Emotionally important events are well remembered. Although memories of emotional experiences are known to be mediated and modulated by the stress hormones glucocorticoids, little is known about the underlying molecular mechanisms. Here we show that the hippocampal glucocorticoid receptors critically engaged during the formation of long–term inhibitory avoidance memory in rats are coupled to the activation of CaMKIIα, TrkB, ERK, Akt, PLCγ and CREB, as well as a significant induction of Arc and synaptic GluA1. Most of these changes, which are initiated by a non–genomic effect of glucocorticoid receptors, are also downstream of the activation of brain–derived neurotrophic factor (BDNF). Hippocampal administration of BDNF, but not other neurotrophins, selectively rescues both the amnesia and the molecular impairments produced by glucocorticoid receptor inhibition. Hence, glucocorticoid receptors mediate long–term memory formation by recruiting the CaMKIIα–BDNF–CREB–dependent neural plasticity pathways.
