Anti-galactose-alpha-1,3-galactose (Anti-Gal) antibody is naturally expressed at a high level in humans. It constitutes about 1% of immunoglobulins found in human blood. Here, the HKU team designed a live-attenuated influenza vaccine that can generate Gal epitopes in infected cells in order to facilitate opsonization of infected cells, thereby enhancing vaccine-induced immune responses. This approach provides a novel strategy for developing next generation influenza vaccines.
Seasonal influenza viruses change constantly so continuous modifications in influenza vaccines are needed to combat season-specific viral strains. Furthermore, Influenza A viruses have multiple HA subtypes that are antigenically diverse and they cannot induce satisfactory heterosubtypic immunity against multiple influenza virus subtypes. Therefore, develop an universal and robust vaccine that can provide protection against flu variants is needed.
Founded in 1911, The University of Hong Kong (HKU) is the first and oldest institution of higher education in Hong Kong. For over a century, the University has dedicated itself to creating knowledge, providing education, and serving society. Today, HKU has an established worldwide reputation for being a research-led comprehensive University with ten Faculties and a strong commitment to intellectual freedom, liberty and diversity. HKU has a proud record of academic recognition in researches through honours and awards received from both local and international bodies.
