| Outline of Final Research Achievements |
Self-assembled nanoparticles (NPs) composed of poly(γ-glutamic acid) (γ-PGA) as a hydrophilic backbone and enantiomeric poly(lactide) (PLA) as a hydrophobic side chain were prepared using stereocomplex (SC) formation of PLA. The γ-PGA-PLA SC NPs exhibit a lower critical aggregation concentration (CAC) as well as stronger kinetic stability compared with the corresponding isomer NPs. Moreover, mouse immunization with ovalbumin (OVA)-encapsulated SC NPs predominantly induced OVA-specific cellular immunity. The findings suggest that the γ-PGA-PLA SC NPs are suitable for protein-based vaccines that are used to induce cellular immunity, such as for infectious diseases, cancer, allergies and autoimmune diseases.
