Retargeting of adenovirus via E-selectin as a viable pathway of infection in tumor necrosis factor-α (TNF-α)-activated human umbilical vein endothelial cells (HUVECs) was investigated. E1, E3-deleted Ad5 expressing cytomegalovirus immediate-early promoter-driven luciferase (Adluc) was coated with a reactive multivalent copolymer based on poly [N-(2-hydroxypropyl) methacrylamide] to generate pHPMA-adenovirus (pcAdluc). This was then retargeted by covalent attachment of a mouse antihuman E-selectin monoclonal antibody (MHES mAb). MHESpcAdluc was efficiently taken up into HUVECs, generating a high level of transduction in TNF-α-treated E-selectin positive cells but not in untreated receptor-negative cells. Our results suggest that E-selectin could be a valuable target for gene transfer strategies internalizing polymer-coated adenovirus particles through a viable receptor-mediated endocytosis pathway, generating adequate levels of transgene expression per virus genome copy.
