Chronic obstructive pulmonary disease (COPD) is significantly influenced by oxidative stress. Recent studies have elucidated the anti-oxidative stress properties of peroxisome proliferator-activated receptors γ (PPARγ), augmenting its known anti-inflammatory effects. The exact influence of PPARγ on oxidative stress in COPD remains elusive. This study aimed to investigate the potential mechanism by which PPARγ counteracts the oxidative stress instigated by cigarette smoke in macrophages.
