Brief Summary:
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.

Arm Intervention/treatment
Active Comparator: A
Inhalation of Fluticasone (via discus) twice daily for 28 days
Drug: fluticasone
Participants inhale fluticasone (250 µg) via discus. Before and after this therapy, a bronchoalveolar lavage is performed.
Active Comparator: B
Inhalation of Fluticasone and Salmeterol (via discus) twice daily for 28 days
Drug: fluticasone/salmeterol
Participants inhale fluticasone/salmeterol (250/50µg) via discus. Before and after this therapy, a bronchoalveolar lavage is performed.
Placebo Comparator: C
Inhalation of Placebo (via discus) twice daily for 28 days.
Drug: placebo
Participants inhale placebo twice daily via discus. Before and after this therapy, a bronchoalveolar lavage is performed.



Primary Outcome Measures :
  1. The number and the CCR7 expression of DCs in bronchoalveolar lavage fluid before and after therapy with fluticasone or fluticasone/salmeterol, as compared to placebo. [ Time Frame: 2 time points (A and B). Time point A: day 0 (directly before the inhalation therapy). Time point B: day 29 (directly after the inhalation therapy). ]

Secondary Outcome Measures :
  1. The expression of other surface molecules on DCs in bronchoalveolar lavage fluid before and after therapy with fluticasone or fluticasone/salmeterol, as compared to placebo. [ Time Frame: 2 time points (A and B). Time point A: day 0 (directly before the inhalation therapy). Time point B: day 29 (directly after the inhalation therapy). ]
