精神疾病是人类癫痫的常见合并症。在匹罗卡品诱导的癫痫持续状态(SE)后,实验动物不仅出现自发性反复发作,而且表现出明显升高的攻击行为。引发这些行为改变的细胞和分子机制尚不清楚。在本研究中,我们发现攻击性与自发性癫痫发作的发生呈正相关。雷帕霉素(一种有效的mTOR途径抑制剂)治疗可显著减少攻击行为。因此,mTOR通路可能在导致癫痫相关攻击的潜在分子机制中具有重要意义。
Psychiatric disorders are fairly common comorbidities of epilepsy in humans. Following pilocarpine-induced status epilepticus (SE), experimental animals not only developed spontaneous recurrent seizures, but also exhibited significantly elevated levels of aggressive behavior. The cellular and molecular mechanism triggering these behavioral alterations remains unclear. In the present study, we found that aggression is positively correlated with development of spontaneous seizures. Treatment with rapamycin, a potent mTOR pathway inhibitor, markedly diminished aggressive behavior. Therefore, the mTOR pathway may have significance in the underlying molecular mechanism leading to aggression associated with epilepsy.
