CD46 and infection: To determine whether human CD46 expression enables infection of murine cells by group B adenovirus, we incubated NMuMG-CD46, CT26-CD46 and their corresponding parental cell lines with EnAd expressing GFP under the control of the CMV immediate-early promoter (EnAd-CMV-GFP) or under a splice acceptor (SA) site of the adenovirus MLP (EnAd-SA-GFP).
