摘要

典型瞬时受体电位通道(trpc)是一类钙渗透阳离子通道。先前的研究表明,由TRPC1和TRPC4组成的异质通道介导侧间隔神经元和海马CA1锥体神经元的癫痫样爆裂,表明TRPC1/4通道起促癫痫发作作用。在这项研究中,我们利用脑电图(EEG)记录和频谱分析来评估TRPC1/4通道在匹洛卡平癫痫持续状态(SE)模型中的作用。我们发现,令人惊讶的是,TRPC1/4双敲除(DKO)小鼠对匹罗卡品诱导的SE的易感性增加。此外,TRPC1/4 DKO小鼠的SE潜伏期也显著降低。需要进一步的研究来揭示我们意想不到的结果的潜在机制。

Increased Susceptibility to Pilocarpine-Induced Status Epilepticus and Reduced Latency in TRPC1/4 Double Knockout Mice
Canonical transient receptor potential channels (TRPCs) are a family of calcium-permeable cation channels. Previous studies have shown that heteromeric channels comprising TRPC1 and TRPC4 mediate epileptiform bursting in lateral septal neurons and hippocampal CA1 pyramidal neurons, suggesting that TRPC1/4 channels play a pro-seizure role. In this study, we utilized electroencephalography (EEG) recording and spectral analysis to assess the role of TRPC1/4 channels in the pilocarpine model of status epilepticus (SE). We found that, surprisingly, TRPC1/4 double knockout (DKO) mice exhibited an increased susceptibility to pilocarpine-induced SE. Furthermore, SE latency was also significantly reduced in TRPC1/4 DKO mice. Further studies are needed to reveal the underlying mechanisms of our unexpected results.
