鼻内给予抗炎药治疗有望缓解多发性硬化症的进展

2020-10-21 MedSci原创 MedSci原创

鼻内给药不会进入循环系统,需要的药量更少,可以直接递送至大脑,并且药物分解速度也不会很快。

阿尔伯塔大学的临床前研究表明,鼻内给予抗炎药有助于缓解多发性硬化症的疾病进展。

研究结果显示,通过鼻内给药向小鼠提供抗炎药可以避免脑细胞受损,从而有效缓解疾病进展。MS是一种破坏性疾病,发病机制不清晰且无法治愈。阿尔伯塔大学Power教授的实验室寻求更好地了解这种疾病,从而开发出有效的治疗方法。

炎症小体是细胞内的多蛋白复合体,过度激活后会引起强烈的炎症反应,进而促进多种炎症性疾病的进展,例如MS。Power实验室探究了炎性小体效应蛋白caspase-1的抑制剂VX-765,是否可以成为MS患者的强效候选疗法。

在小鼠模型中,Power将VX-765溶解在液体中,然后将混合物注入鼻子。研究表明,鼻内给药可有效抑制脱髓鞘、轴突损伤和丢失。MS中髓磷脂和神经的丢失是不可逆的过程,因此任何有助于减缓或阻止这种情况发生的疗法都是MS研究的重要进步。

鼻内给药不会进入循环系统,需要的药量更少,可以直接递送至大脑,而且分解速度也不会很快。
