摘要:

尽管肌萎缩性脊髓侧索硬化症(ALS)的病理学知识已得到显著进步,但此刻唯一可用的治疗方法仍是利鲁唑,其能延长患者三个月的存活时间,并且对生活质量没有任何改善。因此,当务之急是寻找新的替代品来治疗ALS,细胞疗法似乎是一种有希望的治疗策略。文章首次证明了使用脊髓内骨髓细胞(BMMC)治疗ALS小鼠的不同结果。虽然使用这种方法并没有观察到动物模型的生存时间有所增加,但在症状前阶段治疗动物模型显示出了疾病进展延迟。需要重点指出的是,只有在症状期的BMMC处理动物中,可以观察到超过160天的长期生存现象。因此,有必要验证细胞数量是否有增加。这些结果对临床前研究具有重要作用。骨髓细胞治疗ALS正处于起步阶段,在能确定这种方法的真正潜力之前还有许多工作要做。许多研究团队都在紧锣密鼓地研究可以将其转换为临床的最佳方案。然而,直到现在,最好的结果仍是动物寿命仅能延长几周。重要的是继续研究该疾病发生和发展的退行性过程机制,以便进一步延缓该疾病进展。多次注射,特别是静脉内注射,可以维持的效果较长,但关键时仍要在更广阔的给药途径考虑治疗ALS的策略。细胞治疗与基因治疗的组合或许可以得到想要的结果,而药理学方法也应该被添加到治疗的具体目标当中。最后,炎症似乎是ALS的一个潜在问题,也应被视为ALS疾病治疗研究中的潜在目标。

Abstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that causes progressive muscular atrophy and death within 3–5 years after its onset. Despite the signifcant advances in knowledge of ALS pathology, no effective treatment is available. Therefore, it is imperative to search for new alternatives to treat ALS. Cell therapy, especially using bone-marrow cells, has showed to be very useful to protect the neural tissue in different brain disease or traumatic lesions. In ALS, most published results show benefcial effects of the use bone marrow cells, especially mesenchymal stromal cells. However, until now, the best outcome extends animal’s lifespan by only a few weeks. It is essential to continue the search for a really effective therapy, testing different cells, routes and time-windows of administration. Studying the mechanisms that initiate and spread the degenerative process is also important to fnd out an effective therapy. Therefore, we discussed here some progresses that have been made using bone-marrow cell therapy as a therapeutic tool for ALS.
