SAM-pointed domain ETS factor mediates epithelial cell-intrinsic innate immune signaling during airway mucous metaplasia.

Airway mucus plays a critical role in clearing inhaled toxins, particles, and pathogens. Diverse toxic, inflammatory, and infectious insults induce airway mucus secretion and goblet cell metaplasia to preserve airway sterility and homeostasis. However, goblet cell metaplasia, mucus hypersecretion, and airway obstruction are integral features of inflammatory… CONTINUE READING
