Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Airway dendritic cells (DCs) play a key role in smoke-related lung diseases. In this study, the researchers investigate the effects of fluticasone and salmeterol on human airway DCs in smokers. The researchers hypothesize that fluticasone and salmeterol impact on the number and the characteristics of airway DCs in smokers.
