Research interest
Baculovirus expression vector system is a commonly used eukaryotic protein expression system. It accommodates extensive eukaryotic post-translational modifications and enables appropriate oligomerization of complex proteins. Currently, the system has been used to produce subunit vaccines for influenza and COVID-19. Our laboratory intends to apply the baculovirus expression system to the following research:
1. Development of serology analysis systems and vaccine antigens for emerging infectious diseases. Recombinant baculoviruses and their insect host cells can be engineered into protein surface-display platforms for use as vaccines and serological analysis systems for infectious diseases.
2. Engineering of antigenic proteins or enzymes. We will focus on improving protein expression, immunogenicity, or enzymatic activity of antigens in serum detection systems or vaccines, as well as specialty enzymes for medical and food safety inspections.
3. Viral vector engineering. Baculoviruses allow the insertion of a sizeable foreign gene fragment and can easily enter various cells. We will take advantage of these properties and modify viruses into efficient vectors for gene expression and gene therapy.
