To examine inflammasome activation in response to IAV infection in lung epithelial cells, we measured IL-1β production in normal, human primary bronchial epithelial cells (NHBE) derived from five donors (Table S1) following infection with the H1N1 viruses A/Puerto Rico/8/34 (PR8) and seasonal A/USSR/90/77 (USSR). Here, IL1B is linked to infection.
