Research Article: Glucocorticoid Alleviates Mechanical Stress-Induced Airway Inflammation and Remodeling in COPD via Transient Receptor Potential Canonical Channel
Abstract:
Chronic obstructive pulmonary disease (COPD) is a complex disease of the lung that is characterized by progressive airflow limitation caused by chronic inflammation and airway narrowing. Evidence has suggested that chronic airway inflammation was characterized by infiltration of the various inflammatory cells including neutrophils, macrophages, and lymphocytes into the airway and lung tissue, which was involved in the pathogenesis and progression of COPD.– Airway remodeling is another critical feature of COPD, characterized by epithelial injury, thickening of the basement membrane or subepithelial fibrosis, mucous gland and goblet cells hyperplasia, increased smooth muscle mass and angiogenesis. Many cytokines such as transforming growth factor ? (TGF-?) and matrix metalloproteinase- (MMP-) play a major role in airway remodeling by induce the epithelial mesenchymal transition (EMT) and extracellular matrix deposition.
