Linkage of a monoclonal antibody against E-selectin demonstrated E-selectin-specific transduction of tumour necrosis factor-α (TNF-α)-activated endothelial cells. A two-component targeting system using protein G was developed. We report an enhancement in transduction of TNF-α-activated endothelium in vitro and ex vivo in a human umbilical vein cord model using the E-selectin antibody. Virus retargeted using a chimeric P-selectin Glycoprotein Ligand-1-Fc fusion (PSGL-1) protein showed better circulation kinetics and uptake into HepG2 xenografts following systemic administration in mice, with 36-fold higher genome copies, compared with non-modified virus. Immunohistochemistry of tumour sections from mice treated with PSGL-1-retargeted virus showed a co-localisation of luciferase with CD31 suggesting selective endothelial targeting.
