    • Recombinant adeno-associated virus (rAAV) vectors are provided for delivery of regulatable transgenes to the central nervous system (CNS) of a mammal. Also provided are methods of treatment of subjects with neurodegenerative disorders using the vectors, and kits for constructing or using the vectors or performing the methods of the invention. Transgene sequences are expressed from a promoter/enhancer region comprising one or more binding sites for a transcription factor that is responsive to a small molecule inducer. Both the transgene construct and a construct comprising the transcription factor are delivered to the target cells. The regulatable transgene may be delivered on the same rAAV vector as the transcription factor, or on a separate vector. The transcription factor may comprise two polypeptide chains, e.g. a DNA binding domain and a transcription activation domain, that form an active dimer in the presence of a dimerizer such as rapamycin or a non-immunogenic analog thereof. Vectors, methods and kits of the invention may be used to deliver genes such as AADC or GDNF to the brain of a subject with a neurodegenerative disorder, such as Parkinson's disease, where the expression of AADC or GDNF in the brain can subsequently be regulated by treatment of the subject with rapamycin or a rapamycin analog.
    • 提供重组腺相关病毒(rAAV)载体用于将可调节转基因递送至哺乳动物的中枢神经系统(CNS)。 还提供了使用载体治疗患有神经变性疾病的受试者的方法,以及用于构建或使用载体或执行本发明的方法的试剂盒。 转基因序列由启动子/增强子区表达,所述启动子/增强子区包含对小分子诱导物有反应的转录因子的一个或多个结合位点。 转基因构建体和包含转录因子的构建体均被递送至靶细胞。 可调节的转基因可以在与转录因子相同的rAAV载体上递送,或者在单独的载体上递送。 转录因子可以包含两条多肽链,例如 DNA结合结构域和转录激活结构域,其在二聚体如雷帕霉素或其非免疫原性类似物的存在下形成活性二聚体。 可以使用本发明的载体,方法和试剂盒将诸如AADC或GDNF的基因递送至具有神经退行性疾病如帕金森病的受试者的脑中,其中脑中AADC或GDNF的表达随后可由 用雷帕霉素或雷帕霉素类似物治疗受试者。
