Halting SARS‐CoV‐2: lung organoids step up to the plate

Defining the pulmonary cell types infected by SARS-CoV-2 and finding ways to prevent subsequent tissue damage are key goals for controlling COVID-19. Recent work establishing a human lung organoid-derived air-liquid interface model permissive to SARS-CoV-2 infection identifies alveolar type II cells as the primary cell type infected, reports an infection-induced interferon response and demonstrates the effectiveness of interferon lambda 1 treatment in dampening lung infection
