摘要: Asthma is characterized by the association of airway hyperresponsiveness (AHR), inflammation, and remodelling. The aim present article to review pivotal role smooth muscle (ASM) in pathophysiology asthma. ASM main effector AHR. mechanisms AHR asthma may involve a larger release contractile mediators and/or lower relaxant mediators, an improved cell excitation/contraction coupling, alteration contraction/load coupling. Beyond its function, also involved bronchial inflammation Whereas target inflammatory process, it can display proinflammatory immunomodulatory functions, through synthetic properties expression wide range surface molecules. remodelling represents key feature asthmatic plays promoting complementary structural alterations, particular function.
