Popis: | Adeno-associated viral (AAV) vectors are one of the most promising gene delivery systems to the central nervous system. We now report, that AAV1 can be used to express transgenes trans-neuronally in neurons distant from the injection site. Specifically, intracortical injection of a bicistronic AAV1 vector trans-neuronally transduced spinal neurons as shown by fluorescence microscopy, the presence of AAV genome and AAV transcript in the contralateral spinal cord. Prior pyramidotomy abolished spinal transduction, confirming anterograde axonal transport of AAV1 in the corticospinal tract. These observations demonstrate the potential of bicistronic AAV1 for trans-neuronal expression of therapeutic transgenes in neurological disorders or reporter genes in connectivity studies. |
