Abstract

Racetam anticonvulsants, such as levetiracetam, are widely prescribed to treat and prevent seizures. Despite decades of clinical use, their mechanism of action remains unclear. Two studies now reveal the structure of the racetam-binding protein SV2A in complex with anticonvulsant drugs, providing insights into their mechanism of action and the physiology of neurotransmission.

对 SV2A 的结构洞察以及拉西坦类抗惊厥药的作用机制
左乙拉西坦等乙酰胆碱类抗惊厥药被广泛用于治疗和预防癫痫发作。尽管已在临床上使用了几十年,但其作用机制仍不清楚。现在,两项研究揭示了与抗惊厥药物复合的拉西坦结合蛋白 SV2A 的结构,为了解它们的作用机制和神经传递的生理学提供了线索。
