The present invention provides a method of providing acute neuroprotection by inducing the erythropoietin (EPO) signaling pathway in neuronal cells close to or subsequent to the time of excitatory insult; and inducing an insulin-like growth factor (IGF) signaling pathway in the neuronal cells close to or subsequent to the time of excitatory insult, thereby producing a synergistic acute neuroprotective effect in the neuronal cells. The invention also provides a method of preventing or reducing the severity of a neurologic condition in a subject by administering to the subject EPO or an active fragment or analog thereof at a dose of at most 2000 U/kg; and administering to the subject an IGF or an active fragment or analog thereof, thereby providing neuroprotection and preventing or reducing the severity of the neurologic condition. Such a method can be used to prevent or reduce the severity of, for example, Alzheimer's disease, Parkinson's disease, Huntington's disease, epilepsy, amyotrophic lateral sclerosis, multiple sclerosis, a movement disorder, HIV-associated dementia, HIV-associated neuropathy, neuropathic pain, migraine, glaucoma, drug addiction, drug withdrawal, drug dependency, depression or anxiety.
本发明提供了一种提供急性神经保护的方法,该方法通过在接近兴奋性损伤时或之后在神经元细胞中诱导促红细胞生成素(EPO)信号通路;以及在接近兴奋性损伤时或之后在神经元细胞中诱导胰岛素样生长因子(IGF)信号通路,从而在神经元细胞中产生协同的急性神经保护效应。本发明还提供了一种预防或减轻受试者神经系统疾病严重程度的方法,即给受试者注射 EPO 或其活性片段或类似物,剂量不超过 2000 U/kg;同时给受试者注射 IGF 或其活性片段或类似物,从而提供神经保护并预防或减轻神经系统疾病的严重程度。这种方法可用于预防或减轻阿尔茨海默病、帕金森病、亨廷顿病、癫痫、肌萎缩侧索硬化症、多发性硬化症、运动障碍、HIV相关性痴呆、HIV相关性神经病、神经性疼痛、偏头痛、青光眼、药物成瘾、药物戒断、药物依赖、抑郁或焦虑等疾病的严重程度。
