In one study fritillaria reduced airway inflammation by suppressing cytokines, histamines, and other compounds of inflammatory response.

Dust mite-induced signals are then propagated through epithelium, which enhance allergic airway inflammation.

Loss of this enzyme leads to enhanced allergic eosinophilic airway inflammation.

These microbial infections result in chronic lower airway inflammation, impaired mucociliary clearance, an increase in mucous production and eventually asthma.

Other treatment options may target airway inflammation or may promote mucus expectoration.
