제목 Retargeting of Adenoviral Gene Delivery via Herceptin-PEG-Adenovirus Conjugates to Breast Cancer Cells
초록 Gene therapy using viral vectors have evolved to become highly efficient for gene delivery to specific cell types while avoiding immunosurveillance by an infected host. Human epidermal growth factor receptor 2 (HER2/neu) overexpressing breast cancer- targeted adenoviral gene delivery is one of the promising strategies for enhancing the transduction efficacy of PEGylated adenovirus (PEG-ADV). The viral capsid of adenovirus carrying the green fluorescent protein (GFP) was conjugated with bifunctional polyethylene glycol (PEG).Then, the surface of PEG-ADV was conjugated with therapeutic monoclonal antibody (MAb), Herceptin (Trastuzumab; HER)to grant cell specific targeting. The PEG-ADV and Herceptin immobilized PEG-ADV (HER-PEG-ADV) were evaluatedtheir extents of retargeting, as compared to those of naked ADV.
