The former, intracranially complements patients some factors, most frequently with TH gene to compensate scanty of intrastriatal DA and improve the symptoms of the patients, while have little resistance to the progressive degeneration of dopaminergic neurons; The latter provide variety of neurotrophic factors, most specific being the glial cell-line derived neurotrophic factor , to protect the residual DA neurons in the nigrostriatal system from further pathogenic injuries, while have little benefit to those DA neurons with irreversible damage, and them cannot offset the already-existing symptoms.

前者是给宿主脑内补充某些因子，主要是DA合成过程中的限速酶TH基因，以补充纹状体内DA含量的不足，减轻患者的症状，但对DA能神经元的进行性退变没有治疗效果；后者则是提供各种神经营养因子其中最具特异性的为GDNF，以保护黑质一纹状体系统内剩余的DA能经元免受病因的继续损害但对已发生不可逆性损害的DA能神经元并无拯救作用，无法消除已出现的症状。
