Apoptosis of Alveolar Wall Cells in Chronic Obstructive Pulmonary Disease Patients with Pulmonary Emphysema Is Involved in Emphysematous Changes / 华中科技大学学报（医学）（英德文版）

s of alveolar wall cells, espe-cially apoptosis of type-Ⅱ cells, may take part in the pathogenesis of emphysema. Up-regulation of Bax expression may be responsible for the apoptosis of alveolar wall cells in the COPD patients with pulmonary emphysema.
