Neuronal Marker (神经细胞标志物)
酪氨酸羟化酶（TH）是儿茶酚胺类神经递质即多巴胺、去甲肾上腺素、肾上腺素生物合成过程所需的限速酶，它以四氢生物喋呤啶(BH4)为辅酶，催化酪氨酸的羟化而生成多巴(DOPA)。
已知在患帕金森病(Parkinson disease,PD)时，脑内多巴胺(dopamine,DA)的减少与此酶活性低下有关。因此对PD模型动物来说，若将TH基因植入脑内，便可以提高脑内DA水平而达到基因治疗目的.
Tyrosine hydroxylase is involved in the conversion of tyrosine to dopamine. As the rate-limiting enzyme in the synthesis of catecholamines, tyrosine hydroxylase has a key role in the physiology of adrenergic neurons. Tyrosine hydroxylase is regularly used as a marker for dopaminergic neurons, which is particularly relevant for research into Parkinson's disease.
