帕金森病 (PD) 是一种使人衰弱的神经系统疾病,约 2% 的 50 岁以上人群患有帕金森病。目前的假设认为,帕金森病的病因是多因素的,涉及环境因素和遗传倾向。 1-甲基-4-苯基-1,2,3,6-四氢吡啶 (MPTP) 可在包括人类在内的许多物种中诱导帕金森病,并在小鼠中表现出品系特异性。然而,菌株特异性的机制仍然未知。使用新型嵌合鼠黑质培养物,我们证明对 MPTP 的敏感性是由神经胶质细胞赋予的,并且它不涉及 MPTP 到 MPP+ 的 MAO-B 转化。暴露于 MPP+ 的 C57Bl/6J 多巴胺能神经元在 C57Bl/6J 神经胶质细胞上培养时表现出 39% 的损失,而在抗性 SWR/J 神经胶质细胞上培养时神经元损失 17%。同样,暴露于 MPP+ 的 SWR/J 神经元在 SWR/J 神经胶质细胞上培养时表现出 4% 的损失,但在敏感的 C57Bl/6J 神经胶质细胞上培养时表现出 14% 的损失。神经胶质细胞被鉴定为实验性帕金森病发生的关键细胞类型,为开发新的抗帕金森病疗法提供了目标。 GLIA 34:73–80, 2001。© 2001 Wiley-Liss, Inc.
Parkinson's disease (PD) is a debilitating neurological disorder that strikes approximately 2% of people over age 50. Current hypotheses propose that the cause of PD is multifactorial, involving environmental agents and genetic predisposition. 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (MPTP) induces parkinsonism in many species, including humans and shows strain specificity in mice. The mechanism of strain specificity, however, remains unknown. Using novel chimeric murine substantia nigra cultures, we demonstrate that sensitivity to MPTP is conferred by glia and that it does not involve the MAO‐B conversion of MPTP to MPP+. C57Bl/6J dopaminergic neurons exposed to MPP+ demonstrated a 39% loss when cultured on C57Bl/6J glia compared with 17% neuron loss when cultured on resistant SWR/J glia. Similarly, SWR/J neurons exposed to MPP+ demonstrated a 4% loss when cultured on SWR/J glia, but a 14% loss when cultured on sensitive C57Bl/6J glia. The identification of glia as the critical cell type in the genesis of experimental Parkinsonism provides a target for the development of new anti‐parkinsonian therapies.
