神经元兴奋和抑制之间的不平衡是多种神经精神疾病的核心特征,因此需要开发新的策略来校准治疗的兴奋-抑制平衡。在这里,我们鉴定了一种天然化合物槲皮素,它可以减少前额皮质 GABA 能传递并减轻谷氨酸能 N-甲基-d-天冬氨酸受体拮抗剂 MK-801 引起的过度活跃。槲皮素以非竞争性方式显着降低培养的皮质神经元中的 GABA 激活电流,并适度抑制小鼠前额皮质切片中的自发和电诱发的 GABA 抑制性突触后电流。值得注意的是,槲皮素的全身和前额叶特异性递送除了减轻 MK-801 诱导的多动症外,还减少了基础运动活动。槲皮素的作用并不完全依赖于含有 α5 亚基的 A 型 GABA 受体 (GABAAR),因为病毒介导的前额皮质 α5 亚基的区域特异性基因敲除改善了 MK-801 诱发的精神病症状,但保留了对槲皮素的药理学反应。两种干预措施一起使运动活动完全正常化。总之,槲皮素作为负变构 GABAAR 调节剂发挥抗精神病活性,促进兴奋性抑制失衡疾病的进一步治疗开发。
An imbalance between neuronal excitation and inhibition represents a core feature in multiple neuropsychiatry disorders, necessitating the development of novel strategies to calibrate the excitatory–inhibitory balance of therapeutics. Here we identify a natural compound quercetin that reduces prefrontal cortical GABAergic transmission and alleviates the hyperactivity induced by glutamatergic N-methyl-d-aspartate receptor antagonist MK-801. Quercetin markedly reduced the GABA-activated currents in a noncompetitive manner in cultured cortical neurons, and moderately inhibited spontaneous and electrically-evoked GABAergic inhibitory postsynaptic current in mouse prefrontal cortical slices. Notably, systemic and prefrontal-specific delivery of quercetin reduced basal locomotor activity in addition to alleviated the MK-801-induced hyperactivity. The effects of quercetin were not exclusively dependent on α5-subunit-containing A type GABA receptors (GABAARs), as viral-mediated, region-specific genetic knockdown of the α5-subunit in prefrontal cortex improved the MK-801-evoked psychotic symptom but reserved the pharmacological responsivity to quercetin. Both interventions together completely normalized the locomotor activity. Together, quercetin as a negative allosteric GABAAR modulator exerted antipsychotic activity, facilitating further therapeutic development for the excitatory–inhibitory imbalance disorders.
