- Develop effective and safe vaccines and therapeutic antibodies to prevent and treat emerging infectious diseases caused by coronaviruses, including Middle East respiratory syndrome coronavirus (MERS-CoV), severe acute respiratory syndrome coronavirus (SARS-CoV), SARS-CoV-2, and other coronaviruses with pandemic potential, influenza viruses, as well as transfusion-transmitted flaviviruses.
- Study pathogenic mechanisms of these viruses, based on which to design novel vaccines and therapeutic antibodies.
- MERS-CoV vaccines and pathogenic mechanisms. We have identified MERS-CoV spike protein receptor-binding domain (RBD) as an important vaccine target, and demonstrated that MERS-CoV RBD contains a critical neutralizing domain capable of inducing cross-neutralizing antibodies against infection of divergent MERS-CoV strains. Current research focus is to design and develop safe, efficacious, and novel MERS vaccines with low-cost, manufacturing capacity, broad-spectrum efficacy, and enhanced potency, identify their protective mechanisms, and study pathogenic mechanisms of MERS-CoV.
- Other coronavirus vaccines and pathogenic mechanisms. We have shown that SARS-CoV-2 and SARS-CoV spike proteins and RBDs are important vaccine targets. We are working on the development of novel spike protein and/or RBD-based vaccines against SARS-CoV-2 (COVID-19), SARS-CoV and other coronaviruses with pandemic potential, study of their protective mechanisms, as well as identification of pathogenic mechanisms of these coronaviruses.
- Therapeutic antibodies against pathogenic coronaviruses. We have demonstrated that coronavirus spike proteins and RBDs are important therapeutic targets. Current research focus is to design and develop spike protein and/or RBD-targeting novel therapeutic antibodies against emerging coronaviruses with pandemic potential.
We have identified that ZIKV envelope protein domain III is an important vaccine target in inducing specific antibody responses, cross-neutralizing antibodies, and protection against infection of divergent ZIKV strains. We have established mouse models susceptible to ZIKV infection, and utilized them to evaluate efficacy of ZIKV vaccines and therapeutic agents. Current research focus is to design and develop novel, safe, and effective ZIKV vaccines and therapeutics with improved efficacy, study ZIKV transmission and blood safety, and understand pathogenic mechanisms of ZIKV.
