生酮饮食被用作耐药性癫痫的饮食治疗,但没有基于生酮饮食的抗癫痫药物。生酮饮食改变大脑中的能量代谢物(酮体、葡萄糖和乳酸盐),从而改变神经元的电活动,并最终抑制癫痫患者的癫痫发作。为了阐明生酮饮食的抗癫痫作用,重要的是要阐明这些代谢变化转化为神经元电变化的机制。在这篇综述中,我们总结了电生理学研究的重点是神经元的生酮饮食的电控制。最近的研究已经确定了生酮饮食驱动的电调节剂:离子通道(ATP敏感性K+通道和电压依赖性Ca 2+通道),突触受体(AMPA型谷氨酸受体和腺苷A1受体),神经递质转运蛋白(囊泡谷氨酸转运蛋白)和其他(BCL-2相关的细胞死亡和乳酸脱氢酶激动剂)。因此,生酮饮食可能通过这些分子的联合作用增强神经元抑制。从药物开发的角度来看,这些分子是有价值的新的抗癫痫药物的开发目标。通过靶向这些分子的多种抗癫痫药物的组合,模拟生酮饮食的药物治疗在未来可能是可行的。
The ketogenic diet is used as a diet treatment for drug-resistant epilepsy, but there are no antiepileptic drugs based on the ketogenic diet. The ketogenic diet changes energy metabolites (ketone bodies, glucose and lactate) in the brain, which consequently changes electrical activities in neurons and ultimately suppresses seizures in epileptic patients. In order to elucidate the antiseizure effects of the ketogenic diet, it is important to clarify the mechanism by which these metabolic changes are converted to electrical changes in neurons. In this review, we summarize electrophysiological studies focusing on electrical control in neurons by the ketogenic diet. Recent studies have identified electrical regulators driven by the ketogenic diet: ion channels (ATP-sensitive K+ channels and voltage-dependent Ca2+ channels), synaptic receptors (AMPA-type glutamate receptors and adenosine A1 receptors), neurotransmitter transporters (vesicular glutamate transporters), and others (BCL-2-associated agonist of cell death and lactate dehydrogenase). Thus, the ketogenic diet presumably elicits neuronal inhibition via the combined actions of these molecules. From the viewpoint of drug development, these molecules are valuable as targets for the development of new antiepileptic drugs. Drug therapy to mimic the ketogenic diet may be feasible in the future, through the combination of multiple antiepileptic drugs targeting these molecules.
