Th1/Th2/Th17‑related cytokines in the bronchoalveolar lavage fluid of patients with sarcoidosis: association with smoking

Abstract

We confirmed a significant role of IL‑6, IFN‑γ, and IL-17A in the local inflammatory response in sarcoidosis. However, the interpretation of the limited number of cytokine measurements should be made with caution. Further studies are needed to explain the effect of smoking on the pathomechanism of inflammation in sarcoidosis.
