摘要:

帕金森病(Parkinson's disease,PD)的特征是黑质致密部多巴胺能神经元的丢失,虽然恢复纹状体多巴胺水平可以改善症状,但没有任何治疗方法可以治愈或逆转疾病本身。干细胞疗法具有再生作用,目前正被积极研究作为治疗帕金森病的候选疗法。间充质干细胞(MSCs)因较少涉及伦理问题、较低的免疫排斥风险和较低的致畸风险而被认为是一种有前景的选择。此文以评估间充质干细胞及其衍生物对运动功能、记忆力和多巴胺能神经元在帕金森病动物模型中的干预效果。检索了文献数据库(PubMed/MEDLINE、Embase、CENTAL、Scopus 和 Web of Science)以确定文章,仅纳入了 2023 年 6 月 28 日之前以任何语言发表的经同行评审的体内干预性动物研究。研究采用随机效应模型来估计治疗组和对照组之间标准平均差 (SMD) 的 95% 置信区间 (CI)。使用实验动物实验系统综述中心的偏倚风险工具和动物研究荟萃分析和综述协作方法清单进行研究质量评估。共有33项研究的840只帕金森病模型动物的数据被纳入分析。通过苯丙胺诱导的旋转测试评估,间充质干细胞治疗可明显改善运动功能。在干细胞类型中,含有神经营养因子的骨髓间充质干细胞组显示出最大效应(SMD [95% CI] = -6.21 [-9.50 to -2.93],P = 0.0001,I2 = 0.0 %)。干细胞治疗组纹状体([95% CI] = 1.04 [0.59 to 1.49],P = 0.0001,I2 = 65.1 %)和黑质(SMD [95% CI] = 1.38 [0.89 to 1.87],P = 0.0001,I2 = 75.3 %)中酪氨酸羟化酶阳性多巴胺能神经元明显增多,表明对多巴胺能神经元有保护作用。对苯丙胺诱导的旋转测试进行的分组分析显示,只有颅内-脑干途径的测试结果显著降低(SMD [95% CI] = -2.59 [-3.25 to -1.94], P = 0.0001, I2 = 74.4 %)。只有静脉途径的记忆测试显示出明显改善(SMD [95% CI] = 4.80 [1.84 to 7.76],P = 0.027,I2 = 79.6 %)。研究表明,间充质干细胞对运动功能、记忆功能有积极影响,并能在帕金森病临床前模型中保护多巴胺能神经元。要确定这些方案的最佳干细胞类型、修饰、移植细胞数量和输送方法,还需要进一步研究。

Abstract: Parkinson’s disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta, and although restoring striatal dopamine levels may improve symptoms, no treatment can cure or reverse the disease itself. Stem cell therapy has a regenerative effect and is being actively studied as a candidate for the treatment of Parkinson’s disease. Mesenchymal stem cells are considered a promising option due to fewer ethical concerns, a lower risk of immune rejection, and a lower risk of teratogenicity. We performed a meta-analysis to evaluate the therapeutic effects of mesenchymal stem cells and their derivatives on motor function, memory, and preservation of dopaminergic neurons in a Parkinson’s disease animal model. We searched bibliographic databases (PubMed/MEDLINE, Embase, CENTRAL, Scopus, and Web of Science) to identify articles and included only peer-reviewed in vivo interventional animal studies published in any language through June 28, 2023. The study utilized the random-effect model to estimate the 95% confidence intervals (CI) of the standard mean differences (SMD) between the treatment and control groups. We use the systematic review center for laboratory animal experimentation’s risk of bias tool and the collaborative approach to meta-analysis and review of animal studies checklist for study quality assessment. A total of 33 studies with data from 840 Parkinson’s disease model animals were included in the meta-analysis. Treatment with mesenchymal stem cells significantly improved motor function as assessed by the amphetamine-induced rotational test. Among the stem cell types, the bone marrow MSCs with neurotrophic factor group showed largest effect size (SMD [95% CI] = –6.21 [–9.50 to –2.93], P = 0.0001, I2 = 0.0 %). The stem cell treatment group had significantly more tyrosine hydroxylase positive dopaminergic neurons in the striatum ([95% CI] = 1.04 [0.59 to 1.49], P = 0.0001, I2 = 65.1 %) and substantia nigra (SMD [95% CI] = 1.38 [0.89 to 1.87], P = 0.0001, I2 = 75.3 %), indicating a protective effect on dopaminergic neurons. Subgroup analysis of the amphetamine-induced rotation test showed a significant reduction only in the intracranial-striatum route (SMD [95% CI] = –2.59 [–3.25 to –1.94], P = 0.0001, I2 = 74.4 %). The memory test showed significant improvement only in the intravenous route (SMD [95% CI] = 4.80 [1.84 to 7.76], P = 0.027, I2 = 79.6 %). Mesenchymal stem cells have been shown to positively impact motor function and memory function and protect dopaminergic neurons in preclinical models of Parkinson’s disease. Further research is required to determine the optimal stem cell types, modifications, transplanted cell numbers, and delivery methods for these protocols.
