帕金森病是目前中老年人最常见的神经系统变性疾病之一。路易小体中α-突触核蛋白(α-Synuclein, α-Syn)异常聚集与帕金森病密切相关 [ 1] ,而细胞自噬功能障碍是导致α-Syn清除障碍和异常聚集的重要因素 [ 2- 3] 。姜黄素是从姜黄根茎中提取的一种多酚类物质,具有诱导自噬激活的作用,近年来研究发现其对帕金森病具有保护作用 [ 4- 5] ,但具体机制尚未明确。本研究诱导SH-SY5Y细胞建立帕金森病细胞模型,评价姜黄素对多巴胺能神经元、α-Syn、转录因子EB(transcription factor EB,TFEB)及自噬相关蛋白的影响,探讨姜黄素保护多巴胺能神经元的作用机制。

帕金森病是一种以黑质多巴胺能神经元变性坏死为主要病理特征的常见神经系统退行性疾病,其发病率和致残率高。目前,帕金森病治疗以药物为主,中药在帕金森病治疗中具有独特作用。姜黄素具有抗肿瘤、抗氧化、抗炎症及器官保护等多种药理作用 [ 6] ,近年来逐渐用于帕金森病治疗。研究表明,姜黄素在多种帕金森病小鼠模型中表现出抗炎、抗氧化等作用,可减少氧化应激和线粒体损伤,改善小鼠运动障碍,发挥神经保护作用 [ 7- 13] 。在帕金森病细胞模型中姜黄素也表现出抗氧化应激、减少线粒体损伤、调节细胞内钙离子释放等作用,从而保护多巴胺能神经元、减少细胞死亡 [ 14- 17] 。本研究采用MPTP诱导建立帕金森病细胞模型,TH免疫荧光结果显示姜黄素可增加多巴胺能神经元存活数,减少MPTP所致的神经毒性作用。

帕金森病的发病与多种机制相关,其中细胞自噬功能障碍致α-Syn清除受损在其中发挥重要作用,因此能够激活自噬的药物可通过促进α-Syn自噬性清除来治疗帕金森病 [ 18] 。经典的自噬激活剂雷帕霉素在帕金森病细胞和动物模型中对多巴胺能神经元具有保护作用 [ 19] ,证实了上述观点。研究表明,姜黄素具有诱导自噬的功能,在肺癌、肝癌、恶性胶质细胞瘤等多种肿瘤细胞模型中可诱导自噬从而抑制肿瘤细胞生长 [ 20- 22] ; 阿尔茨海默病动物模型证实,姜黄素可通过下调PI3K/Akt/mTOR信号途径诱导自噬、抑制β淀粉样蛋白形成,发挥神经保护作用 [ 23] 。因此我们推测姜黄素在帕金森病中同样具有诱导自噬的功能,并可能通过此功能发挥神经保护作用。

LC3-Ⅱ作为哺乳动物细胞中自噬体的标志物之一,可反映自噬活性的高低。但也有观点认为,LC3-Ⅱ蛋白表达增加也可能是由于溶酶体功能缺失而并非自噬活性增加。当溶酶体功能缺陷导致自噬途径阻断时,自噬标志物蛋白会因为降解减少而积聚,但这种因积聚而增多的自噬蛋白并不能提高细胞内自噬活性 [ 24] 。因此本实验还测定了LAMP2A蛋白的表达。LAMP2A是一种重要的溶酶体膜蛋白,主要定位于溶酶体膜上,可作为溶酶体的标志物。研究结果显示,姜黄素可以增加帕金森病细胞中LC3-Ⅱ和LAMP2A的表达,提示姜黄素具有激活细胞自噬的作用。姜黄素还可以减少细胞α-Syn的蛋白及mRNA表达,说明其激活的自噬可促进细胞中α-Syn清除,可见细胞自噬激活促进α-Syn自噬性清除是姜黄素对帕金森病发挥神经保护作用的机制之一。自噬抑制剂3-MA和姜黄素同时干预则部分消除了姜黄素对LC3-Ⅱ和LAMP2A的影响,且多巴胺能神经元存活数也相应减少,进一步验证了上述结论。但两者同时干预仍使得多巴胺能神经元存活数较模型对照组增加,α-Syn蛋白及mRNA表达减少,提示激活细胞自噬并不是姜黄素促进α-Syn清除的唯一机制,姜黄素还可能通过其他途径清除α-Syn发挥多巴胺能神经元保护作用。本研究还观察到模型对照组较空白对照组LAMP2A和LC3-Ⅱ表达增加,提示自噬激活;但与此同时α-Syn蛋白表达增加,TH阳性细胞减少,提示MPTP激活的自噬并没有促进α-Syn的降解,这可能是一种自噬应激现象,蛋白积聚加重导致自噬性细胞死亡,需要今后更深入的研究。

TFEB是细胞自噬的重要调控蛋白。在过表达α-Syn的帕金森病动物模型中,TFEB功能受损可增加多巴胺能神经元对α-Syn毒性的易感性,TFEB过表达则可增强细胞自噬功能,促进α-Syn清除,还有研究发现在帕金森病患者中脑的多巴胺能神经元细胞核内TFEB表达减少 [ 25- 26] 。Song等 [ 27] 发现一种合成的姜黄素衍生物可与TFEB特异性结合,促进TFEB核转运,从而增强自噬和溶酶体功能,但并未抑制雷帕霉素靶蛋白活性。Zhang等 [ 28] 研究发现,姜黄素在激活细胞自噬的同时增加了TFEB蛋白表达,进一步证实TFEB表达增加可能是姜黄素激活自噬的重要途径。3-MA是磷脂酰肌醇3激酶的抑制剂,可特异性阻断自噬体的形成,广泛用作自噬抑制剂。3-MA与姜黄素同时干预并未消除姜黄素对TFEB的影响,可能与两者对自噬的作用途径不同、药物存在相互作用等相关。

综上所述,姜黄素可保护MPTP所致的多巴胺能神经元损伤,激活细胞自噬功能、促进α-Syn自噬性清除可能是作用机制之一;同时,TFEB在细胞自噬过程中发挥重要作用,可能是姜黄素激活自噬的重要途径。此外,姜黄素还可能通过激活AMPK信号通路、抑制PI3K/Akt/mTOR信号通路、增加转铁蛋白受体1和铁调节蛋白1的表达、磷酸化细胞外信号调节激酶1/2信号通路等多种途径激活自噬功能 [ 29- 32] 。因此,姜黄素是帕金森病治疗的一个非常有潜力的中药,但也有学者认为姜黄素药物峰浓度低、口服吸收差、生物利用度低、体内的化学性质不稳定、生物学活性较弱,可能导致临床应用无效 [ 33- 35] 。因此,姜黄素在帕金森病治疗中的作用、机制及其在临床应用的可行性、有效性和安全性等问题需要更多、更深入的研究加以探讨。
