内容記述 |
Modification with antibodies is a useful strategy for the delivery of nanoparticles to target cells. However, the complexity of the required chemical modifications makes them time-consuming and low efficiency, and the orientation of the antibody is challenging to control. To develop a simple, fast, effective, and orientation-controllable technology, we employed staphylococcal protein A, which can bind to the Fc region of antibodies, as a tool for conjugating antibodies to nanoparticles. Specifically, we modified the C-domain dimer of protein A to contain a lysine cluster to create a molecule, DPACK, that would electrostatically bind to anionic liposomes. Using this protein, antibody-modified liposomes can be prepared in 35 minutes with two steps: (1) interaction of DPACK with liposomes and (2) interaction of an antibody with DPACK-modified liposomes. Binding efficiencies of DPACK with liposomes and IgG with DPACK-modified liposomes were 75% and 72-84%, respectively. Uptake of liposomes modified with anti-epidermal growth factor receptor (EGFR) antibodies via DPACK by EGFR-expressing cancer cells was significantly higher than that of unmodified liposomes, and the liposomes accumulated in tumors and colocalized with EGFR. This simple, fast, effective and orientation-controllable technology for preparing antibody-modified liposomes will be useful for active targeting drug delivery. |
