Salt and fluid secretion is normally associated with improved
mucociliary clearance — keeping the airways free of allergens.
«However, prolonged exposure [to Alternaria] leads to disruption of epithelial barrier function that would ultimately reduce
mucociliary clearance,» the researchers wrote.
This spike weakens the airways» barrier defense system that, when functioning normally, removes infection - and allergy - causing organisms (
mucociliary clearance).
