Grand Challenges Grants Program

Summary:

Wild water birds are the main carriers of “bird flu,” which has jumped species into poultry, claiming the lives of more than 58 million birds in the USA in 2022-23, and people, where it presents a risk of becoming another pandemic. Although we think of the flu as being a respiratory infection, in birds the virus can infect both the respiratory tract and the gut, and these organs represent key sites where new flu strains evolve and emerge. However, our understanding of how flu evolves in the avian respiratory tract and gut is lacking. In this project, the team will grow miniature airways and intestines from chickens and ducks in the laboratory (so called primary culture models and “organoids”) and study how bird flu replicates and evolves in them, to mimic what happens in the birds. This will allow the team to answer important questions about how new flu strains emerge, and the barriers to species jumping, in a controlled laboratory setting, without the need for infecting animals.
