    • The present invention relates generally to efficient delivery of viral vectors to cells of the CNS, particularly useful in the treatment of neurodegenerative disorders and motor neuron diseases. The invention involves selecting a first population and a second population of synaptically connected neurons, wherein a therapeutic polypeptide is to be expressed in said second population of neurons; and administering rAAV virions comprising a therapeutic gene to said first subpopulation of neurons of said subject such that the rAAV virions are transported across a synapse between synaptically connected neurons. In another aspect the present invention also comprises the use of rAAV virions carrying a transgene in the preparation of a medicament for the treatment of a disease in a subject, wherein a first population and a second population of synaptically connected neurons are selected and a therapeutic polypeptide is to be expressed in said second population of neurons; and a medicament comprising recombinant adeno-associated virus (rAAV) virions is delivered to said first population of neurons of the subject, wherein said virions comprise a nucleic acid sequence that is expressible in transduced cells to provide a therapeutic effect in the subject, and wherein said rAAV virions are capable of transducing a synaptically connected neurons.
    • 本发明一般涉及向CNS细胞有效递送病毒载体,特别可用于治疗神经变性疾病和运动神经元疾病。 本发明涉及选择第一群体和第二群突触连接的神经元,其中治疗性多肽将在所述第二群神经元中表达; 以及将包含治疗基因的rAAV病毒粒子施用于所述受试者的神经元的所述第一亚群,使得rAAV病毒粒子被跨越突触连接的神经元之间的突触传输。 在另一方面,本发明还包括使用携带转基因的rAAV病毒颗粒在制备用于治疗受试者中的疾病的药物中的用途,其中选择第一群体和第二群突触连接的神经元,并且治疗性多肽 将在所述第二群神经元中表达; 并且将包含重组腺相关病毒(rAAV)病毒粒子的药物递送至受试者的神经元的所述第一群体,其中所述病毒粒子包含在转导的细胞中可表达以在受试者中提供治疗效果的核酸序列,其中 所述rAAV病毒粒子能够转导突触连接的神经元。
