Objective and Significance:
Influenza A viruses cause annual human seasonal epidemics and pandemics at unpredictable intervals. While the 2009 H1N1 pandemic was relatively mild, previous pandemics in 1957 and 1968 caused substantial morbidity and mortality and the pandemic of 1918 was associated with 40-50 million deaths worldwide. Influenza pandemics arise from influenza viruses of animals and spread globally within weeks or months. In addition, the recent COVID-19 pandemic, alarm the importance of novel coronavirus that may cause global public health risk. Vaccine development for novel emerging infectious viruses, in particularly for the recent COVID-19pandemic, initiated after pandemic emergence will not be in time to prevent or mitigate the first pandemic wave. Thus there is an urgent need to be able to better risk-assess animal viruses of both influenza and coronavirus for pandemic threat so that candidate vaccine strains can be developed in advance.
This project aims at investigating the tropism and viral replication competence of influenza A virus and coronavirus isolated from surveillance program in Hong Kong from avian and swine species. In addition, the innate immune responses and pathogenesis of influenza A virus and coronavirus will be monitored using physiological-relevant in vitro models of human respiratory epithelial cells in the laboratory.
Research Plan and Methodology:
Various subtypes of influenza A virus isolated from surveillance program in Hong Kong will be propagated to generate the virus stocks for the project. Coronavirus virus of various disease severity, e.g., OC43, 229E, SARs-CoV-1 and SARS-CoV-2 will be included. The tropism and viral replication competence of influenza A virus and coronavirus will be assessed using human airway organoids and human respiratory explants. The innate immune responses and pathogenesis of influenza A virus and coronavirus will be monitored using in vitro cultures of human alveolar epithelial and human macrophagees. This project involves a variety of virology protein chemistry and molecular techniques from culturing virus, infection of various models to measurement of viral replication competence and innate immune responses.
