Correlation between airway responsiveness and proteoglycan production by bronchial fibroblasts from normal and asthmatic subjects.
Asthma is characterized by an airway remodeling process involving altered extracellular matrix deposition such as collagen, fibronectin and proteoglycans. Proteoglycans determine tissue mechanical properties and are involved in many important biological aspects. Not surprisingly, it has been suggested that proteoglycan deposition may alter airway properties in asthma including airway hyperresponsi
