Conjugation of Multiple Proteins Onto the Surface of PLGA /Lipid Hybrid Nanoparticles

Year: 2024

Type: article

Abstract: ABSTRACT Nanoparticles are increasingly being used in the development of vaccines for disease prevention or treatment. Recent research has demonstrated that conjugating a protein onto the surface of nanoparticles can significantly increase its immunogenicity. Considering various pathogens that threaten human health, multivalent vaccines are often desirable. Up to now, nanoparticle‐based vaccines are mostly limited to one protein per nanoparticle. No research has been conducted to explore the possibility of conjugating more than one protein onto the surface of a nanoparticle. Here we developed a specific conjugation strategy to conjugate multiple proteins to the PLGA/lipid hybrid nanoparticle surface. The maleimide‐thiol Michael addition, Aizde‐DBCO (Dibenzocyclooctyne), and TCO (trans‐cycloctene)‐Tetrazine click chemistry were employed to conjugate three different proteins, subunit keyhole limpet hemocyanin (sKLH), Ovalbumin (OVA), and cross‐reactive material 197 (CRM 197 ), to the surface of PLGA/lipid hybrid nanoparticles (hNPs). The successful results of this study pave the way for developing multivalent vaccines against different pathogens.
