To identify the roles of pyridoxal kinase (PLK) in epileptogenesis and the recovery mechanisms in spontaneous seizure, a chronological and comparative analysis of PLK expression in the gerbil hippocampus was conducted. PLK immunoreactivity in a pre-seizure group of seizure sensitive (SS) gerbils was more strongly detected than that in a seizure resistant (SR) group. The density of PLK immunoreactivity in a 30-min postictal group was significantly lower than that of a pre-seizure group. In a 12 h postictal group, PLK immunodensity recovered to pre-seizure level. The over-expression of PLK in the hippocampus of pre-seizure SS gerbils suggests that PLP play an important role in the modulation of GAD activity and GABA reuptake as mediated by membrane transporter via neurons.
为了确定吡哆醛激酶(PLK)在癫痫发生中的作用以及自发性癫痫发作后的恢复机制,对沙鼠海马中PLK的表达进行了时间顺序和比较分析。癫痫敏感(SS)沙鼠癫痫发作前组中的PLK免疫反应性比癫痫抗性(SR)组中检测到的更强。发作后30分钟组中PLK免疫反应性的密度显著低于发作前组。在发作后12小时组中,PLK免疫密度恢复到发作前水平。癫痫发作前SS沙鼠海马中PLK的过表达表明,磷酸吡哆醛通过神经元经由膜转运体介导在调节GAD活性和GABA再摄取中起重要作用。
