New research from Harvard Chan School shows that, during asthma flare-ups, the mechanical “squeezing” of the airway known as bronchoconstriction can trigger responses in the epithelial cells—those that line the airway—that make bronchoconstriction worsen and persist, creating a self-reinforcing cycle that may contribute to asthma progression.
