尽管帕金森病(PD)相关的mRNA和蛋白质富含亮氨酸重复激酶2(LRRK 2)在哺乳动物大脑中的全面映射,其在健康个体中的生理功能仍然是个谜。基于其结构特征和激酶特性,LRRK 2可能与参与信号通路的其他蛋白质相互作用。在这里,我们显示了广泛的LRRK 2的mRNA和/或蛋白质的表达在扩大或分化的人中脑神经祖细胞(hmNPC)和死后黑质PD患者。在hmNPC分化为神经胶质细胞和神经元后,使用靶向LRRK 2的小干扰RNA双链体,我们观察到由于LRRK 2敲低样品中的细胞凋亡,多巴胺能神经元的数量减少。LRRK 2缺陷型hmNPC表现出升高的细胞周期和细胞死亡相关标志物。总之,hmNPC中LRRK 2表达的减少严重损害多巴胺能神经元的多巴胺能分化和/或存活,最有可能是通过保留或重新激活细胞周期。
Despite a comprehensive mapping of the Parkinson's disease (PD)-related mRNA and protein leucine-rich repeat kinase 2 (LRRK2) in the mammalian brain, its physiological function in healthy individuals remains enigmatic. Based on its structural features and kinase properties, LRRK2 may interact with other proteins involved in signalling pathways. Here, we show a widespread LRRK2 mRNA and/or protein expression in expanded or differentiated human mesencephalic neural progenitor cells (hmNPCs) and in post-mortem substantia nigra PD patients. Using small interfering RNA duplexes targeting LRRK2 in hmNPCs following their differentiation into glia and neurons, we observed a reduced number of dopaminergic neurons due to apoptosis in LRRK2 knockdown samples. LRRK2-deficient hmNPCs exhibited elevated cell cycle- and cell death-related markers. In conclusion, a reduction of LRRK2 expression in hmNPCs severely impaired dopaminergic differentiation and/or survival of dopaminergic neurons most likely via preserving or reactivating the cell cycle.
