Outline of Final Research Achievements

In this project, we aimed to develop a nano-device using a virus capsid subunit for medical application. For this purpose, we applied the virus capsid subunit for a coating material of various artificial beads. We found that the virus capsid subunit derived from VP1 pentamer of simian virus 40 could coat artificial beads without limitation of particle diameter of the beads. By VP1-pentamer coating, dispersity of the naked beads was greatly improved and the coated beads were retained dispersed in the physiological buffer or in the serum. It was also confirmed that the VP1-coated artificial beads where epidermal growth factor (EGF) was immobilized on the surface of the coated beds were selectively accumulated in the EGF receptor overexpressing cells with EGF dependent manner in vitro and in vivo. These findings should be useful in improvement of dispsersity of artificial beds or retention period in the body of the beds in the use of the artificial beds for drug delivery system.
