细胞外谷氨酸增加可能导致左旋多巴诱导的运动障碍,这是帕金森病患者在左旋多巴治疗5-10年后面临的一种衰弱的副作用。针对突触后谷氨酸受体缓解运动障碍的治疗策略可能由于显着的副作用而成功有限。增加谷氨酸摄取可能是另一种减轻过量谷氨酸能神经传递以减轻运动障碍严重程度或延长发病前时间的方法。在大鼠6-羟多巴胺模型中,在黑质纹状体损伤时开始头孢曲松治疗可以减轻酪氨酸羟化酶丧失,同时增加谷氨酸摄取和谷氨酸转运体GLT-1表达。在此,我们在一个已建立的运动障碍模型中,研究了在黑质纹状体损伤后1周,但在左旋多巴之前开始头孢曲松治疗是否可以减少左旋多巴诱导的运动障碍。头孢曲松(200mg /kg,每日1次,连续7天)在6羟多巴胺损伤后第7天(第7 - 13天)开始使用,并每隔一周(第21 - 27,35 - 39天)继续使用,直到研究结束(损伤后第39天,左旋多巴治疗20天)。在慢性左旋多巴治疗期间,头孢曲松显著减少了5个时间点的异常不自主运动。左旋多巴对黑质纹状体损伤后运动障碍的部分恢复不影响头孢曲松。头孢曲松处理的左旋多巴组纹状体GLT-1表达和谷氨酸摄取显著增加。与单独使用左旋多巴组相比,该组纹状体酪氨酸羟化酶损失无显著差异。在黑质纹状体损伤后,但在左旋多巴之前和期间开始使用头孢曲松,可能会减轻运动障碍的严重程度,而不会影响左旋多巴的疗效或减少纹状体酪氨酸羟化酶的损失。
Increased extracellular glutamate may contribute to L-DOPA induced dyskinesia, a debilitating side effect faced by Parkinson’s disease patients 5–10 years after L-DOPA treatment. Therapeutic strategies targeting post-synaptic glutamate receptors to mitigate dyskinesia may have limited success due to significant side effects. Increasing glutamate uptake may be another approach to attenuate excess glutamatergic neurotransmission to mitigate dyskinesia severity or prolong the time prior to onset. Initiation of a ceftriaxone regimen at time of nigrostriatal lesion, can attenuate tyrosine hydroxylase loss in conjunction with increased glutamate uptake and glutamate transporter GLT-1 expression in a rat 6-hydroxydopamine model. Here, we examined if a ceftriaxone regimen initiated 1 week after nigrostriatal lesion, but prior to L-DOPA, could reduce L-DOPA-induced dyskinesia in an established dyskinesia model. Ceftriaxone (200 mg/kg, i.p., once daily, 7 consecutive days) was initiated 7 days post-6-hydroxydopamine lesion (days 7–13) and continued every other week (days 21–27, 35–39) until the end of the study (day 39 post-lesion, 20 days of L-DOPA). Ceftriaxone significantly reduced abnormal involuntary movements at 5 time points examined during chronic L-DOPA treatment. Partial recovery of motor impairment from nigrostriatal lesion by L-DOPA was unaffected by ceftriaxone. The ceftriaxone-treated L-DOPA group had significantly increased striatal GLT-1 expression and glutamate uptake. Striatal tyrosine hydroxylase loss in this group was not significantly different compared to the L-DOPA alone group. Initiation of ceftriaxone after nigrostriatal lesion, but prior to and during L-DOPA, may reduce dyskinesia severity without affecting L-DOPA efficacy or reduction of striatal tyrosine hydroxylase loss.
