New anti-inflammatory targets for chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is associated with chronic inflammation of the peripheral airways and lung parenchyma, which leads to progressive obstruction of the airways. Current management with long-acting bronchodilators does not reduce disease progression, and there are no treatments that effectively suppress chronic inflammation in COPD. An increased understanding of the inflammatory processes that are involved in the pathophysiology of COPD has identified several new therapeutic targets. This Review discusses some of the most promising of these targets, including new antioxidants, kinase inhibitors and drugs that target cellular senescence, microbial colonization, epigenetic regulation of inflammatory gene expression and corticosteroid resistance.
