肌萎缩性脊髓侧索硬化症(ALS)是最常见的运动神经元疾病,目前尚无足够有效的治疗方法。我们在早期研究中报道,脑室内(i.c.v.)注射活动依赖性神经营养因子(ADNF)可改善 G93A-SOD1 转基因小鼠的运动表现,而不会显着延长生存期。在这里,我们发现 i.c.v.注射名为 Colivelin 的合成混合肽,由 ADNF 和 AGA-(C8R)HNG17 组成,AGA-(C8R)HNG17 是 Humanin 的有效衍生物,是一种具有抗阿尔茨海默病活性的生物活性肽,可剂量依赖性地改善 ALS 小鼠的运动性能并延长其生存期。 120 天龄时进行的组织学分析表明,与生理盐水或 ADNF 处理的小鼠相比,Colivelin 处理的小鼠脊髓中运动神经元存活率增加,表明 Colivelin 是一种有前景的用于治疗 ALS 的神经营养肽。 (c) 2006 Elsevier Inc. 保留所有权利。
Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease for which there is no sufficiently effective therapy, We have reported in our earlier Study that intracerebroventricular (i.c.v.) injection of activity-dependent neurotrophic factor (ADNF) improves motor performance of G93A-SOD1 transgenic mice without significant prolongation in Survival. Here, we found that i.c.v. injection of a synthetic hybrid peptide named Colivelin composed of ADNF and AGA-(C8R)HNG17, a potent derivative of Humanin that is a bioactive peptide with anti-Alzheimer's disease activity, dose-dependently improved motor performance and prolonged survival of ALS mice. Histological analysis, performed at the age of 120 days, demonstrated increased motoneuronal Survival in spinal cords of Colivelin-treated mice as compared with saline- or ADNF-treated mice, indicating that Colivelin is a promising neurotrophic peptide for treatment of ALS.
