Representative images are shown for the experimental conditions evaluated. mRFP-expressing cells transduced with either AVV- or LVV-CMV-mRFP are shown in the left hand panels; IR for NeuN or GFAP in the same sections is shown in green on the right. The central column represents the merged images of left and right columns. Yellow colour indicates colocalization which is particularly prominent in A and D. LVV shows preferential transduction for neurones versus glia compared with AVV.
