MicroRNA是一类重要的非编码RNA,其作为细胞内蛋白质水平的转录后调节因子发挥作用。新的研究表明,癫痫持续状态会对大脑内的microRNA水平产生选择性变化,这可能会影响参与神经元结构和兴奋性、神经胶质增生、炎症和凋亡的蛋白质水平。动物研究表明,使用锁核酸修饰的寡核苷酸(“寡核苷酸”)靶向微小RNA可以对癫痫持续状态、癫痫诱导的神经元死亡和随后出现的复发性自发性癫痫发作具有有效作用。因此,基于microRNA的疗法可能具有作为癫痫持续状态的未来治疗的潜力。
MicroRNAs are an important class of non-coding RNA which function as post-transcriptional regulators of protein levels within cells. Emerging work has revealed that status epilepticus produces select changes to microRNA levels within the brain which may impact levels of proteins involved in neuronal structure and excitability, gliosis, inflammation and apoptosis. Animal studies show that targeting microRNAs using locked nucleic acid-modified oligonucleotides (“antagomirs”) can have potent effects on status epilepticus, seizure-induced neuronal death and the later emergence of recurrent spontaneous seizures. Accordingly, microRNA-based therapeutics may have potential as a future treatment of status epilepticus.
