Abstract
|
|
|
|
A key mechanism in the pathogenesis of chronic obstructive pulmonary disease is thought to be an abnormal inflammatory response in the lungs to the inhalation of toxic particles and gases, derived from tobacco smoke, air pollution, and/or occupational exposures. This review highlights the potential participation of several alternative pathogenetic processes, particularly involving the potential participation of biological and pathobiological processes related to aging, including oxidative stress and enhanced expression of markers of senescence/aging in emphysematous lungs, and the potential for enhanced tissue destruction involving alveolar cell apoptosis.
