[Advances in the role of autoimmune mechanisms in chronic obstructive pulmonary disease].

Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease whose pathogenesis mainly involves airway remodelling and alveolar destruction caused by inflammation, protease-antiprotease imbalance, oxidative stress, and imbalance between apoptosis and compensatory repair of lung tissue structure cells. In recent years, the role of the autoimmune response in COPD has attracted widespread attention, but there is still some controversy. This article reviewed the role of autoimmunity in COPD from different perspectives, starting with the relationship between autoimmunity and the pathogenesis of COPD.
