| Abstract: The ability of adenovirus (Ad) to transfect most cell types efficiently(1-3) has already resulted in human gene therapy trials involving the systemic administration of adenoviral constructs(4). 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 rat(6)), 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. |
