Cigarette smoke exposure as a model of inflammation associated with COPD.

Abstract

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation resulting from inflammation-driven pathologies in the lungs that are a consequence of smoking over many years. Given that the disease is increasing globally, understanding the mechanism by which cigarette smoke (CS) causes lung inflammation and exploiting that knowledge to develop effective treatments is urgently required. Animal models of CS exposure are commonly used to examine the inflammatory processes that may be involved in the development of COPD. The protocols described in this unit detail the development of preclinical models of CS-driven lung inflammation. These systems can be utilized to investigate the role of various biological pathways in CS-mediated inflammation and to assess the efficacy of new therapeutic strategies for treating COPD.
