Airway epithelial cells initiate an immune response to inhaled bacteria by

signaling for white blood cells to move from the bloodstream into the lungs and

airway to fight potential infection. Researchers have demonstrated that this

signaling cascade includes the activation of epithelial proteases, a type of

enzyme capable of opening the junctions between the cells in the airway mucosa,

to enable the white blood cells to get through to the site of the infection.
