Airway remodeling and airway smooth muscle in asthma. Abstract Text:

Airway remodeling in asthma has been recognized as structural changes of airways such as smooth muscle hypertrophy (an increase in size of airway smooth muscle cells) and hyperplasia (an increase in the number of airway smooth muscle cells), thickening and fibrosis of sub-epithelial basement membrane, hypertrophy of bronchial glands, goblet cell hyperplasia, and thickening of airway epithelium. In these pathological changes, airway smooth muscle remodeling has been recognized as one of the most important factors related to in vitro and in vitro airway responsiveness and the severity of asthma. Both hypertrophy and hyperplasia have been shown in asthmatic airways by morphometrical analyses, although there is a wide variation in the contribution of each mechanism in each patient. Such changes could also be recognized as a phenotypic modulation of airway smooth muscle. On the background of airway smooth muscle remodeling, the existence of several contributing factors, such as inflammatory mediators, growth factors, cytokines, extra-cellular matrix proteins, and genetic factors have been suggested. On the other hand, recent studies revealed that airway smooth muscle could also be a source of inflammatory mediators promoting airway inflammation. In this article, the recent understanding in the mechanisms of airway smooth muscle remodeling in asthma, its relations to airway inflammation and airway physiology, and possible usefulness of early intervention with inhaled glucocorticoids have been discussed.
