Rapid, reproducible transduction of select forebrain regions by targeted recombinant virus injection into the neonatal mouse brain

Viral vectors can mediate long-term gene expression in different regions of the brain. Recombinant adeno-associated virus (rAAV) and Lenti virus (LV) have both gained prominence due to their ability to achieve specific transduction of various neuronal populations. Whilst widespread gene delivery has been obtained by targeted injection of rAAV in various brain structures, LV has also been utilized for infection of stem cell populations for cell lineage tracing. Both viral vector systems are most commonly used for gene delivery in mature brains, but the great potential of somatic gene delivery into the neonate brain has not been systematically exploited. Here we provide a systematic guideline…
