    • Embodiments of this invention include methods for increasing the amount of the enzyme tyrosine hydroxylase (TH) in the central nervous system (CNS) of mammals in need of an increase in TH. Methods include the use of the tripeptide, gly-pro-glu (GPE) to increase TH in the CNS. GPE can increase the amount of TH and/or decrease the loss of TH in conditions characterized by a loss of dopamine, such as Parkinson's disease and CNS injury. GPE may act to increase the expression of TH or by inhibiting a decrease in TH expression within the CNS or by inhibiting the loss of TH-containing neurons within the CNS. By increasing the amounts of TH in the CNS, GPE can increase the amount of the neurotransmitter, dopamine, in areas of the CNS responsible for adverse symptoms of neural injury or disease.
    • 本发明的实施方案包括增加需要增加TH的哺乳动物的中枢神经系统(CNS)中酪氨酸羟化酶(TH)的量的方法。 方法包括使用三肽,gly-pro-glu(GPE)来增加CNS中的TH。 GPE可以增加TH的量和/或减少特征为多巴胺损失的疾病如帕金森病和CNS损伤的TH损失。 GPE可以起作用以增加TH的表达或通过抑制CNS内TH表达的降低或抑制CNS内TH含神经元的损失。 通过增加中枢神经系统中的TH量,GPE可以增加CNS负责神经损伤或疾病的不良症状的区域的神经递质,多巴胺的量。

    • The tripeptide glycine-proline-glutamine (GPE) may be administered before, or usually after, injury to reduce damage to the central nervous system. GPE appears useful for neuronal rescue particularly but not exclusively within the hippocampus. Advantages of GPE include: (a) that it crosses the blood-brain barrier, so is effective by injected peripheral administration, (b) it is unlikely to challenge the immune system, (c) it is cheap, and (d) its therapeutic ratio is high. GPE may also be infused into the CSF. It may be administered prior to parturition or elective brain or cardiac surgery. Transdermal routes may be useful for chronic neural disorders. The CNS of mammals (including foetal mammals) after trauma including hypoxic/ischaemic experimental insults showed reduced damage under GPE protection as measured by histological assessment of cell damage or death and regional shrinkage.
    • 三肽甘氨酸 - 脯氨酸 - 谷氨酰胺(GPE)可以在损伤之前或通常在损伤后施用以减少对中枢神经系统的损伤。 GPE似乎对神经元的拯救有用,特别是但不限于海马内。 GPE的优点包括:(a)它穿过血脑屏障,因此通过注射的外周给药是有效的,(b)不可能挑战免疫系统,(c)它是便宜的,和(d)其治疗 比例高。 GPE也可以输入CSF。 它可以在分娩或选择性脑或心脏手术之前进行。 透皮途径可用于慢性神经障碍。 包括缺氧/缺血性实验性损伤在内的哺乳动物(包括胎儿哺乳动物)的CNS显示,在通过细胞损伤或死亡和区域收缩的组织学评估测量的GPE保护下减少的损伤。
