Transduction of the choroid plexus and ependyma in neonatal mouse brain by vesicular stomatitis virus glycoprotein-pseudotyped lentivirus and adeno-associated virus type 5 vectors

Hum Gene Ther. 2005 Jan;16(1):49-56. doi: 10.1089/hum.2005.16.49.


Evaluation of gene transfer into the developing mouse brain has shown that when adeno-associated virus serotype 1 (AAV1) or AAV2 vectors are injected into the cerebral lateral ventricles at birth, widespread parenchymal transduction occurs. Lentiviral vectors have not been tested by this route. In this study, we found that injection of lentiviral vectors pseudotyped with vesicular stomatitis virus glycoprotein (VSV-G) resulted in targeted transduction of the ependymal cells lining the ventricular system and the choroid plexus along the entire rostrocaudal axis of the brain, whereas a Mokola pseudotype transduced only a few cells after injection into the neonatal ventricle. In contrast, when lentiviral vectors pseudotyped with either VSV-G or Mokola glycoprotein are injected into the adult mouse brain, they transduce similar patterns of cells. An Ebola-Zaire-pseudotyped vector did not transduce any neonatal CNS cells, as was also the case for adult parenchymal injections. Long-term gene expression (12 months) occurred with a constitutively active mammalian promoter and a self-inactivating long terminal repeat (LTR), whereas the cytomegalovirus promoter in a vector with an intact LTR was expressed only in short-term experiments. We found that an AAV5 vector also targeted the ependymal and choroid plexus cells throughout the ventricular system. This vector exhibited limited penetration from the ventricle to other structures, which was significantly different from the previously reported patterns of transduction after intraventricular injection of AAV1 and AAV2 vectors.
