Late post-traumatic epilepsy following severe head trauma has been well documented. While there is increasing evidence suggesting that iron-induced lipid peroxidation of neural membranes may accompany cerebral haemorrhage, the pathogenic processes of post-traumatic epileptogenesis remain unknown. Furthermore, the effective prophylactic use of standard anticonvulsant drugs is unsubstantiated. The rational design of therapeutic agents specific for the prevention and treatment of post-traumatic epilepsy hinges on understanding the molecular membrane events at the epileptogenic focus. This study employs the techniques of theoretical quantum pharmacology to provide a structural analysis of neural phospholipid membranes, investigating changes in membrane integrity at the epileptogenic focus as the molecular basis for seizure activity. Molecular mechanics calculations and molecular dynamics simulations were used to model the biochemical events of the epileptogenic focus. We predict that applications of quantum pharmacological techniques to model biochemical events may provide an understanding of proconvulsive pathogenic mechanisms in post-traumatic epilepsy.
严重头部创伤后迟发性创伤性癫痫已有充分记录。虽然越来越多的证据表明,脑出血可能伴随铁诱导的神经细胞膜脂质过氧化,但创伤后癫痫发生的致病过程仍然未知。此外,标准抗惊厥药物的有效预防性使用也缺乏依据。针对创伤后癫痫的预防和治疗的治疗药物的合理设计取决于对癫痫病灶处分子膜事件的理解。本研究采用理论量子药理学技术对神经磷脂膜进行结构分析,研究癫痫病灶处膜完整性的变化,将其作为癫痫发作活动的分子基础。分子力学计算和分子动力学模拟被用于模拟癫痫病灶处的生化事件。我们预测,应用量子药理学技术对生化事件进行建模可能有助于理解创伤后癫痫的促惊厥致病机制。
