腺病毒(Ad)有效地抑制大多数细胞类型的能力1 -3已经导致了涉及腺病毒构建体的全身施用的人类基因治疗试验4。然而,由于脑功能的复杂性和非侵入性监测神经元基因表达的改变的困难,Ad基因治疗策略用于治疗CNS疾病的潜力一直难以评估。在本研究中,我们已经使用了一个广告编码精氨酸加压素cDNA(AdAVP)5在AVP缺陷型尿崩症的动物模型(Brattleboro大鼠6),这使我们能够长期监测成功的基因治疗治疗的非侵入性测定。将AdAVP注入下丘脑视上核(SON),可引起大细胞神经元表达AVP。这伴随着每日饮水量和尿量减少,以及持续4个月的尿渗透压升高。这些数据表明,导致神经系统疾病的单个基因缺陷可以用基于腺病毒的策略来纠正。这项研究强调了使用Ad基因治疗长期治疗CNS疾病的潜力。
The ability of adenovirus (Ad) to transfect most cell types efficiently1–3 has already resulted in human gene therapy trials involving the systemic administration of adenoviral constructs4. However, because of the complexity of brain function and the difficulty in noninvasively monitoring alterations in neuronal gene expression, the potential of Ad gene therapy strategies for treating disorders of the CNS has been difficult to assess. In the present study, we have used an Ad encoding the arginine vasopressin cDNA (AdAVP)5 in an AVP-deficient animal model of diabetes insipidus (the Brattleboro rat6), which allowed us to monitor chronically the success of the gene therapy treatment by noninvasive assays. Injection of AdAVP into the supraoptic nuclei (SON) of the hypothalamus resulted in expression of AVP in magnocellular neurons. This was accompanied by reduced daily water intake and urine volume, as well as increased urine osmolality lasting 4 months. These data show that a single gene defect leading to a neurological disorder can be corrected with an adenovirus-based strategy. This study highlights the potential of using Ad gene therapy for the long-term treatment of disorders of the CNS.
