Emphysema is caused by chemical irritants in cigarette smoke damaging lung tissue, leading to phagocyte recruitment that produces elastase. High elastase concentrations then override inhibitors, breaking down elastic fibers in the alveolar wall.
Les irritants chimiques de la fumée de cigarette endommagent le tissu pulmonaire, le recrutement de phagocytes produisant de l'élastase, la dégradation des fibres élastiques de la paroi alvéolaire, des concentrations élevées d'élastase surpassent l'inhibiteur d'élastase.
