最近一项研究表明,免疫系统中的一类特殊的细胞对于脑损伤修复具有重要的作用,这一发现对于治疗多发性硬化等神经性损伤具有积极的意义。

这项研究是由来自贝尔法斯特女王大学的研究者们做出的,它被认为是揭示脑损伤修复机制方面的里程碑式的研究。全球范围内有230万人受到了多发性硬化的影响,这项研究也许能够帮助患者走出疾病的困扰。

多发性硬化(MS)是一种常见于年轻人的神经性疾病,主要是由于神经元髓鞘磷脂的损伤导致的。在多发性硬化中,免疫系统错误地将髓鞘作为异源物质进行攻击,从而冬至神经系统的损伤,并产生例如失明、痛苦、疲劳以及麻痹等症状。

到如今为止,临床上对多发性硬化的治疗措施也仅仅限于限制疾病的恶化,但无法做到修复损伤的神经元。而最近的这项研究的一大突破点在于其找到了免疫细胞在修复髓鞘损伤方面的作用。

该研究结果发表在最近一期的《nature neuroscience》杂志上,结果显示免疫系统中一类细胞分泌的蛋白质能够靶向大脑干细胞并且诱导其分化成熟形成少突细胞由于修复髓鞘。这项研究意味着研究者们能够利用这一技术开发出一种新型的疗法用于治疗多发性硬化。

该研究的高级作者,Denise Fitzgerald博士也曾遭受过一种类似于多发性硬化疾病的困扰,因此在她21岁的时候不得不重新走路。“这项研究对于我们对神经元损伤自然修复的理解具有重要的意义。这不仅扩展了我们对神经学领域的理解,而且有可能能够改善多发性硬化患者的生活水平”。
