睫状神经营养生长因子被认为是中枢神经系统疾病的潜在治疗药物。我们首次报道了睫状神经营养生长因子肽模拟物Cintrofin在大鼠癫痫持续状态模型中的体内数据。Cintrofin阻止了doublecortin阳性神经元祖细胞数量的长期变化,并减弱了基底树突的持久性。相比之下,Cintrofin既不影响海马细胞增殖和神经发生的急性癫痫持续状态相关的变化,也没有发现任何相关的癫痫发作活动的影响。而癫痫持续状态造成了显着的障碍,在空间学习的逆转肽治疗的大鼠,Cintrofin治疗的大鼠的性能没有显着差异,从控制。该研究证实,Cintrofin包含模拟其母体分子作用的活性序列。虽然数据反对抗癫痫作用,但它们表明Cintrofin具有推定的疾病改善作用。
Ciliary neurotrophic growth factor is considered a potential therapeutic agent for central nervous system diseases. We report firstin vivodata of the ciliary neurotrophic growth factor peptide mimetic Cintrofin in a rat post-status epilepticus model. Cintrofin prevented long-term alterations in the number of doublecortin-positive neuronal progenitor cells and attenuated the persistence of basal dendrites. In contrast, Cintrofin did neither affect acute status epilepticus-associated alterations in hippocampal cell proliferation and neurogenesis nor reveal any relevant effect on seizure activity. Whereas status epilepticus caused a significant disturbance in spatial learning in reversed peptide-treated rats, the performance of Cintrofin-treated rats did not differ from controls. The study confirms that Cintrofin comprises an active sequence mimicking effects of its parent molecule. While the data argue against an antiepileptogenic effect, they indicate a putative disease-modifying impact of Cintrofin.
