Ferritin as a Nanoparticle Scaffold for Plant‐Produced Next‐Generation Subunit Vaccines

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Protein nanoparticles offer an innovative approach to next‐generation subunit vaccine development by displaying antigenic sequences on the nanoparticle surface. Compared to traditional subunit vaccines, protein nanoparticle vaccines often show improved interaction with the immune system due to their particulate size and repetitive epitope ...
