| Outline of Final Research Achievements |
In this research, a novel platform for enzyme application, which allows for expansion of its scope and durability of enzyme activity in in vivo conditions, was pioneered, particularly using polymeric hollow capsule PICsomes with a size of ~100 nm. In this project, the following three topics were mainly investigated: (1) Enzyme-based biodetoxification nanosystem, (2) Nano-delivery system for enzyme replacement therapy, (3) Nano-delivery system of light source in in vivo conditions. In the topic of (1), PICsome containing histamine degradation enzyme was developed, and successful performance was confirmed in in vivo experiments using model mice. In the topic of (2), milder methods for enzyme encapsulation was developed, and effective factor for cellular internalization of the PICsome system was revealed. In the topic (3), bioluminescent enzyme, Nano-Luc, was successfully encapsulated into PICsomes, and its activity was confirmed for future development of light-driven nanosystem.
