Within-host antigenic selection of influenza A virus dominates over stochasticity but is limited by fitness tradeoffs and timing of the immune response

Vedhika Raghunathan, Christina Marcelo Leyson, Matthew A. Gaddy…·Anice C. Lowen

This study shows that antigenic selection of influenza virus within hosts is driven by immune pressure timing and fitness tradeoffs, with moderate stochastic effects observed.

Viral lineage and mode of exposure modulate within host spatial dynamics of influenza A viruses

Christina M. Leyson, Nahara Vargas-Maldonado, Matthew A. Gaddy…·Anice C. Lowen

This study shows that influenza A virus lineage and exposure route affect its spatial distribution and genetic diversity within the respiratory tract of guinea pigs.
